        <taPart2Item1aUnitNamesEnterInterest>Virtu Americas LLC ("VAL" or the "Firm") operates MatchIt ATS ("MatchIt" or the "ATS"), which consists of a Main Session (the "Main Session"), a Conditional Session (the 
"Conditional Session"),and one or more Hosted Sessions (see Part III, Item 14 for more detail on Hosted Sessions).  VAL also operates several other business units, which are described below.  Any 
of the Firm's other business units may enter or direct orders to any session.  The Firm's business 
units each use one or more technology platforms that have MPIDs associated with the platform.  A 
single business unit can enter or direct orders to the ATS through more than one technology 
platform and consequently under more than one MPID.  

Virtu Electronic Trading ("VET").  VET provides algorithms that are used by clients and the Firm's 
business units.  VET algorithms enter or direct the entry of orders to MatchIt as agent when those 
orders are entered by clients into the algorithms or as principal or riskless principal when one of 
the other business units enters orders into the algorithms using the MPIDs: VALR 
and VALX.   

Virtu Client Market Making ("VCMM").  VCMM handles held and not held orders transmitted by 
other broker-dealers and held orders transmitted by institutions.  The majority of these orders are 
SEC Rule 605 eligible orders and are handled and executed on a fully automated basis.  VCMM 
sales and trading personnel handle larger and less liquid orders manually and can use VET 
algorithms in connection with their market making activities.  VCMM enters or directs the entry of 
orders to MatchIt as principal, riskless principal and agent to acquire inventory to fill orders or to 
acquire positions for its own account using the following MPIDs: VALR and 
VALX.   

Virtu Institutional Trading ("Institutional Trading").  Institutional Trading handles not held orders 
transmitted by institutional clients and facilitates block transactions in single stocks.  Institutional 
Trading uses VET algorithms to enter or direct the entry of orders as principal or riskless principal 
in connection with its client facilitation activities under the MPID VALX.

Virtu Hi-Touch Portfolio Trading: Traders on this desk handle not held orders in baskets of stocks 
and ETFs. Traders can enter or direct the entry of orders through VAL Electronic Systems into the 
ATS as agent under the MPID VALR. 

Virtu ETF Trading ("ETF Trading").  ETF Trading makes markets on exchanges and facilitates 
block transactions in exchange traded products for broker-dealer and institutional clients.  ETF 
Trading uses VET algorithms to enter or direct the entry of orders as principal or riskless principal 
in ETFs and singles stocks using the MPID VALX. 

Virtu Principal Market Making ("VPMM"). VPMM is a market maker in NMS equity securities. 
VPMM enters or directs the entry of orders as principal to both MatchIt crossing sessions utilizing 
the MPID VIRT.</taPart2Item1aUnitNamesEnterInterest>

        <taPart2Item3aExplianOptOut>The Firm and its Affiliates provide algorithms to clients which enter or direct the entry of orders to MatchIt and other trading centers. These clients are Indirect Subscribers of the ATS. The Firm makes the Virtu Principal Opt Out available only to these Indirect Subscribers. This opt out will prevent interaction with VAL orders submitted by VPMM, as described in Part II, Item 1(a). See, Part III, Item 7 addressing order types and instructions; and Part III, Item 14 addressing counterparty selection. 
Indirect Subscribers may not opt out of interaction with principal orders related to the facilitation of client orders. Direct Subscribers are broker-dealers, including VAL, VAL affiliates, and clients that have been approved to send orders directly to MatchIt. Clients acting as a Direct Subscribers do not have the option to opt out of interacting with the orders and trading interest of the Broker-Dealer Operator. 
For Indirect Subscribers opting out of interacting with eligible orders, the Firm sets a configuration in the Indirect Subscriber's algorithmic profile settings. When the algorithms enter or direct an order to MatchIt, the configuration is checked and an opt-out instruction is placed on the FIX Protocol message. The ATS's matching logic reads these messages to determine which orders are eligible for matching.</taPart2Item3aExplianOptOut>

VAL permits Indirect Subscribers to be either broker-dealers or institutional type customers. VAL does not permit Indirect Subscribers to directly choose the available ATS order types and instructions or to directly enter or direct the entry of orders through the API VAL makes available to Direct Subscribers. VAL algorithms make all decisions about when and how to enter or direct the entry of orders and conditional interest into the ATS. See, Part II, Items 1; and Part III, Item 5(c).

        <taPart2Item6aUnitAfflEmployeeServices>VAL does not have any personnel whose sole responsibility is for MatchIt.  The Firm considers 
information relating to Subscriber's live orders, trading interests and recent executions in MatchIt 
that the Firm reasonably believes may suggest a Subscriber continues at that moment in time to 
have the same or additional live orders and trading interests in MatchIt to be ATS confidential 
information ("Confidential Information").  As is more fully discussed in Part III, Item 7(a), the 
Firm does not consider all post trade data to be Confidential Information, particularly when the 
information is anonymized, aggregated or both.           

Below is a summary of the shared personnel that provide services to both MatchIt, the Firm, and 
its Affiliates and have access to Confidential Information.  
*	Compliance and Legal:  Compliance and Legal personnel support all of the Firm's business 
units and those of the Firm's Affiliates and perform a variety of compliance and legal 
activities related to their roles.  They have access to Subscriber real-time and historical order and 
execution information.
*	Finance and Management Reporting Group:  Finance and Management Reporting 
personnel support all of the Firm's business units and those of the Firm's Affiliates.  These 
personnel are involved in accounting, billing, analyzing revenues, and providing 
management reporting information.  They have access to Subscribers' real-time and historical order and execution information and data.    
*      US Executive Management: Certain US executive management personnel have access to information for oversight purposes, including real-time and historical ATS information. 
*	Operations:  Operations personnel support the Firm's middle and back office processes for 
clearance and settlement and related activities and have access to Subscribers' real time 
intra-day, post-trade, and historical execution information for clearing, settlement, and 
regulatory reporting purposes.  
*	Core Operations:  Core Operations are technical personnel who have access to the Firm's 
and its Affiliates' trading infrastructure, which includes MatchIt, to monitor the 
functionality, health, and wellness of the Firm's trading infrastructure and take action as 
necessary to maintain the systems and manage issues.  They have access to Subscribers' 
real-time and historical order and execution information.  This group supports all trading 
infrastructure and applications for the Firm.
*	Software Developers:  Software Developers have access to the Firm's and its Affiliates' 
trading infrastructure, which includes MatchIt, to maintain and enhance the software for 
the Firm's trading applications.  They have access to Subscribers' real-time and historical 
order and execution information.  This group supports all trading infrastructure and 
applications for the Firm.
*	Product Management: Product Management are personnel who manage the day-to-day 
business activities for products such as MatchIt, the algorithms the Firm provides to 
clients, and other trading-related applications the Firm and its Affiliates provide to clients.  
These personnel monitor the trading applications, enhance their product features, and 
create new features.  Product Management compile and analyze statistics and metrics 
related to the ATS and other electronic products and services.  Product Management works 
with Software Developers, and in some instances are also Software Developers themselves.  
The Product Manager responsible for supervising MatchIt is also the Product Manager 
responsible for supervising 'VAL's other ATS, POSIT, and also provides support to both 
VAL's VET business and 'execution services applications. Product Management have 
access to Subscribers' real-time and historical order and execution information.  
*	Relationship Management:  Relationship Management personnel are responsible for 
managing the Firm's relationship with its clients, including clients who are Direct 
Subscribers of the ATS, and for cross-selling the Firm's other products and services.  They 
have access to historical order and execution information.     
*	Sales and/or Trading Personnel:  To the extent Sales or Trading personnel are responsible 
for handling an order, a portion of which is directed to MatchIt as a child order, such 
personnel would have real time access to such child order and any of its executions in 
MatchIt analogous to the access they would have to information about orders and 
executions that were directed to external market centers in order to monitor executions and 
provide order-related services.</taPart2Item6aUnitAfflEmployeeServices>

accessing MatchIt directly. 

The Data Centers provide services that include, building security; air conditioning; access to electricity and telecommunication services; and cages for computer equipment. The Firm owns and maintains its own computer hardware and network devices within the data center.  Please see Part II, Item 6 for more detail. For details on trade reporting to TRFs see Part III, item 21.

      <taPart2Item7aDescrOfSafeGaurdsAndProcedures>GENERAL BACKGROUND AND SCOPE OF CONFIDENTIAL INFORMATION. The Firm 
operates MatchIt on a matching engine that runs on a standalone server in the NY5 Data Center. 
See Part I, Item 7; and Part III, Item 6(a).  The MatchIt matching engine communicates with 
shared systems to book trades, to report executed trades to the tape, to facilitate clearance and 
settlement, for financial reporting and billing, and to facilitate other post-trade processes.  See Part 
II, Item 6 for information on personnel that have access to Confidential Information.
AGGREGATED ANONYMOUS DATA.  Data which has been aggregated and which does not 
identify any Subscribers is not Confidential Information ("Aggregated Anonymous Data").  The 
Firm publishes firm-wide aggregated anonymous execution data to market wide trade 
advertisement systems after the transaction has been reported to the consolidated tape.  The data 
does not include any client identities but does include symbol level executed volumes.  'While the 
Firm does not consider this data to be Confidential Information, it does not include MatchIT 
Aggregated Anonymous data in these reports.  
The Firm posts monthly statistics on its website and disseminates this data to Subscribers ("the 
Monthly MatchIt Statistics").  The Monthly MatchIt Statistics are available at  
https://www.virtu.com/about/transparency and provide aggregate and anonymous information 
about MatchIt, including total volume; volume by sector; volume by market cap; fill size 
distribution; and distribution of executions at the bid, mid and offer.  The Firm produces market 
commentary from time-to-time that discusses general market trends.  The statistical data described 
in this paragraph can be used to produce market commentary.  The Firm considers this data to be 
Aggregated Anonymous Data and not Confidential Information.  The Firm does not permit 
Subscribers to opt out of having their data included in these reports.        
SALES DATA.  Sales Data is aggregated information about the products and services the Firm's 
clients use and includes the client's name, the product or service they use, aggregate executed 
volume, and revenues ("Sales Data").  Sales Data includes aggregated ATS data as described in the 
preceding sentence.  The Firm provides Sales Data to management personnel, Sales or Trading 
personnel and Relationship Management personnel who are involved in handling relationships 
with the Firm's clients.  Sales Data is provided for the purpose of allowing these personnel to keep 
abreast of the client's business activities to manage the client relationship and to cross sell the 
Firm's products and services to the client.  The Firm does not consider Sales Data to be 
Confidential Information when distributed internally for the above described purposes.  The Firm 
makes this information available in end of day reports and in sales systems (i.e., systems that 
support activities of Sales or Trading personnel and Relationship Management personnel for the 
purposes described above) on T+1.  The Firm prohibits personnel from disclosing Sales Data to 
third parties.  The Firm does not permit Subscribers to opt out of having this data made available 
to personnel involved in handling client relationships, as defined in Part II, Item 6(a).      
PERSONNEL WITH ACCESS TO CONFIDENTIAL INFORMATION.  The Firm does not have 
any personnel whose sole responsibility is for the operations of MatchIt.  The shared personnel 
discussed in response to Part II, Item 6(a), have access to Confidential Information.  
SAFEGUARDS AND OVERSEEING CONFIDENTIAL INFORMATION.  The Firm maintains 
written policies and procedures regarding use and protection of Confidential Information.  Firm 
personnel are subject to its parent, Virtu Financial Inc.'s Code of Conduct and Employee Manual. 
Firm personnel are also subject to the Firm's Information Security Policy, Compliance Manual, 
and Written Supervisory Procedures.      
These policies prohibit the personnel listed in Part II, Item 6(a), from sharing Confidential 
Information with other personnel who are not in one of these permitted categories or with any 
other person.  The exception is that Compliance and Legal personnel may provide information to 
regulators in response to regulatory requests or to third parties pursuant to subpoena.  Personnel 
who violate the Firm's policies concerning Confidential Information are subject to discipline, 
including termination of their employment.  The Firm performs email reviews and employs data 
loss software as a means of safeguarding Confidential Information.  
The Firm procedures require that personnel make requests for access to its systems through the 
Firm's access ticketing system and to receive approval from a supervisor prior to being granted 
access to any systems.  The Firm's supervisory personnel grant access to systems on the premise 
that it is necessary to perform their duties and to carry out the purpose for which the information is 
provided to them.  The supervisor responsible for MatchIt approves requests for access to the 
MatchIt matching engine.  The Firm only permits approved personnel in the categories described 
in Part II, Item 6(a), to have access to Confidential Information and only permits these personnel 
to access the systems and the Confidential Information contained therein using approved means of 
access and credentials.  Supervisors do not grant access to Confidential Information. The Firm 
maintains a process that sends notifications to designated personnel to disable systems access for 
personnel who are no longer employed by the Firm.  Supervisors are responsible for instructing the 
technology personnel to disable access when employees change roles.  The Firm provides reports 
to the supervisors that show personnel with access to the MatchIt matching engine on a monthly 
basis.  Supervisors review these reports to ensure that these personnel still require access to carry 
out responsibilities related to the ATS.    
PERSONAL TRADING RESTRICTIONS.  The Firm maintains employee trading policies that 
require personnel to disclose their own personal accounts and the accounts of close family 
members, that prohibit personnel from trading based on any client Confidential Information, that 
require personnel to pre-clear transactions and attest at the time of trade entry that they are not 
trading on Confidential Information, and that prescribe holding periods for securities purchases. 
The Firm conducts reviews of employee trading to determine whether trades were pre-cleared and 
whether holding periods were observed.</taPart2Item7aDescrOfSafeGaurdsAndProcedures>

        <taPart2Item7bExplainHowAndConditions>By virtue of their use of MatchIt, VAL considers all Subscribers to have consented to the disclosure of Confidential Information as described in Part II, Item 6(a) and consented to the disclosure of aggregated and anonymous data to the public and Sales Data to management personnel, Sales or Trading personnel and Relationship Management personnel internally as described in Part II, Item 7(a) above. 
Subscribers may consent to disclosure of their own Confidential Information to any person they choose by submitting a written request to their Sales or Trading person, Relationship Management person describing the nature of the information the wish to disclose and the scope of the disclosure they wish to make. For example, a Subscriber may wish to request that their data be disclosed to a Sales or Trading person to monitor their activity or for analysis.</taPart2Item7bExplainHowAndConditions>

The sales person will create a ticket for operation staff to carry out the request. In most cases, the request will be honored on the next business day, but could take effect either the same day or greater than the next business day, depending upon the time of day the request is submitted. Sales and Operations will verify that the request has been implemented.
Otherwise, the Firm does not permit Subscribers to opt out of having their Aggregated Anonymous Data included in the Monthly MatchIt, in market commentary that uses this data, or from having Sales Data provided to management personnel, Sales or Trading personnel and Relationship Management personnel, for the purposes noted in Part II, Item 6(a).</taPart2Item7cExplainHowAndConditions>

        <taPart3Item2bSummaryOfCndtns>VAL permits applicants who satisfy eligibility requirements to become Direct Subscribers. Specifically, in addition to being registered broker-dealers, Direct Subscribers must execute an electronic access agreement, and submit the standard on-boarding documentation that all clients of VAL must submit. Such documentation includes "know your customer" information, financial information to assess counterparty risk and establish a trading limit, and relevant agreements such as AGUs or Qualified Service Representative (QSR) to facilitate trade clearance. VAL performs reviews to assess a client's prior disciplinary history. A disciplinary history related to market abuse, for example, would potentially preclude a prospective client from being on-boarded to VAL and consequently would preclude the client from being permitted access to the ATS. A client that does not have sufficient net capital or a clearing firm with sufficient net capital to satisfy the Firm's counterparty risk criteria would similarly be precluded from becoming a client of the Firm's and consequently not be permitted access to the ATS. A client who holds less than $500,000 in capital will only be granted access if: there is a formal request with business head approval; the nature of the business flow is such that large MTM exposures are unlikely; and the revenues provide sufficient risk vs. reward ratios, or the company is part of a larger group and there are explicit or implicit guarantees, or there is a high degree of confidence the company will grow.
The Product Manager for the ATS approves or denies access to the ATS. Clients who are not approved for access to the ATS would generally also not be approved for any other VAL services. 
Indirect Subscribers are not required to be broker-dealers but would otherwise go through the same on-boarding process. VAL generally only on-boards clients to use algorithms that are broker-dealers or institutional type clients and does not accept natural persons as clients.</taPart3Item2bSummaryOfCndtns>

        <taPart3Item3aExcludngSumryDtls>VAL has discretion to exclude Subscribers for any reason. Subscribers may be excluded as a result of regulatory or counterparty risk concerns which would generally result in the Subscriber being excluded from all services provided by the Broker-Dealer Operator of the ATS. The same criteria listed in Part III, Item 2 which would preclude a prospective client from a client of VAL and being granted access to the ATS could also result in an existing Subscriber from being excluded from access to the ATS and from other services provided by VAL. For example, a disciplinary history related to market abuse or a change in financial condition such that the Subscriber fails to satisfy VAL's counterparty risk criteria could preclude a Subscriber from continued access to the ATS.
Direct Subscribers do not have access to the Conditional Session or Hosted Sessions, See, Part III, Item 11 and 14.

      <taPart3Item7AOrdrTypExplain>For the Main Session, MatchIt accepts Peg orders, Day orders and Immediate or Cancel (IOC) orders.  
Peg and Day orders may cross with contra-side Peg orders, contra-side Day orders or with IOC orders. 
IOC orders may only cross with contra-side Peg orders or contra-side Day orders. These order types may 
be entered with other instructions that will be used by the matching algorithm to determine whether and 
how they will interact with other orders.  

For the Conditional Session, MatchIt accepts Peg orders and IOC orders.  Peg orders may cross with contra-side 
Peg orders or with IOC orders.  IOC orders may only cross with contra-side Peg orders.  These order types may be 
entered with other instructions that will be used by the matching algorithm to determine whether and how they 
will interact with other orders.

For Hosted Sessions, all order types and attributes are the same as the Main Session.

Priority in the MatchIt Main Session and Hosted Sessions for all order types is price, then time.  If a Subscriber modifies the 
terms of a previously transmitted order, the order will receive a new order time stamp for matching 
purposes (i.e. the order will lose queue spot). The only exception is a reduction in order quantity which, 
absent any other changes to the terms of the order, will not update the order time stamp for matching 
purposes.  

Priority in the MatchIt Conditional Session for all order types is price, then size, then time.   If the 
algorithm modifies the terms of a previously transmitted order, the order will receive a new order time 
stamp for matching purposes (i.e., the order will lose queue spot). The only exception is a reduction in 
order quantity which, absent any other changes to the terms of the order, will not update the order time 
stamp for matching purposes.

The following instructions are available for orders entered in the Main Session, the Conditional 
Session, and Hosted Sessions.  The instructions placed on orders will affect whether an order is eligible to be executed against 
contra-side orders.    
(1) Peg Orders: Peg orders remain open until executed, canceled by the Subscriber or until the end of the 
daily matching session. Peg orders can be designated with the following execution instruction:

      (i) Market: A Market instruction designates that the order can pay the full spread. For example, a 
buy order can be executed up to the national best offer and a sell order can be executed down to the 
national best bid. 

      (ii) Mid-Point: A Mid-Point instruction designates that an order can pay up to the mid-point 
between the national best bid and national best offer ("NBBO"). 

      (iii) Primary: A Primary instruction designates that the order can only be executed at the national 
best bid in the case of a buy order and the national best offer in the case of a sell order.
      
A Limit Price instruction can be specified for Peg orders in conjunction with the above referenced 
execution instruction.  

(2) Day Orders: Day orders remain open until executed, canceled by the Subscriber or until the end of the 
daily matching session. Day orders can also include a Market, Mid-Point, Primary or Limit Price 
instruction.

(3) IOC Orders: IOC orders will either execute if an eligible contra side order exists against which the 
order can be executed or if not the order is canceled.  IOC orders can also include a Market, Mid-Point, 
Primary, or Limit Price instruction.   IOC orders will default to Primary Peg if a peg instruction is not 
specified.

Other available Instructions and Designations for the Main, Conditional, and Hosted Sessions: The following 
instructions may be applied to the above order types unless otherwise indicated. These instructions may be 
implemented by transmitting specified values on the order or by requesting configurations that will apply 
particular instructions after receipt of the order: 

(i)	Minimum Execution Quantity (MEQ): An MEQ instruction specifies the minimum 
number of shares that must be available for a contra side order to be eligible for execution. 

(ii)	Locked Market: A Locked Market instruction specifies that an order is not eligible for 
execution during locked markets. IOC orders entered with a Locked Market instruction 
will be rejected if the NBBO is locked. Peg orders will be accepted but ineligible for 
execution until the NBBO unlocks.

(iii)	Peg Order Add-Only Liquidity Instruction ("Add Only"): An Add-Only instruction 
specifies that the order is only eligible for execution when it adds liquidity to MatchIt upon 
entry. Peg orders that would remove liquidity from MatchIt will be accepted by MatchIt 
and remain open but ineligible for execution until such a time as the order adds liquidity to 
MatchIt. Contra-side Peg orders on the book at the time a Peg order with an Add Only 
instruction is entered will not interact with the Peg Add Only order.

(iv)	Soft Dollar Instruction: A Soft Dollar instruction will only allow riskless principal or 
agency crossing. To the extent that an order with a Soft Dollar instruction interacts with an 
order submitted by VCMM, MatchIt will pass information on the execution message so 
that the market maker's systems transact with its underlying client according to FINRA's 
definition of "riskless principal," i.e., at the same price, as the execution received in 
MatchIt.

(v)	Virtu Principal Opt Out: VAL and VAL Affiliates may submit instructions on orders 
that prevent interactions with Virtu principal orders, as described in Part II, item 3(a). 
This instruction is not available to Direct Subscribers. 

(vi)	MatchIt Subscriber Profiles and Limits on Interaction: This instruction specifies the 
types of counterparties that an order may interact with based on the counterparty's 
Liquidity Profile. MatchIt uses quantitative metrics to create one or more Liquidity 
Profiles for each MatchIt Subscriber. The metrics include execution performance relative 
to the market over different time horizons when removing liquidity from MatchIt.  
MatchIt makes discretionary decisions in assigning a Liquidity Profile to a new or 
previously uncategorized Subscribers. MatchIt will inform Subscribers about their own 
profile information upon request. 
(vii)	Self-Match Prevention: Subscribers may provide instructions that will prevent 
orders from crossing if the resulting cross may result in a transaction with no change 
in beneficial ownership.

        <taPart3Item9aMsgUsgDtls>The MatchIt Conditional Session accepts Conditional Orders and IOC orders. Direct Subscribers do not have access to the Conditional Session. See, Part III, Item 7 and Item 11 for additional information regarding Conditional Orders and the Conditional Session. Only VAL, its Affiliates, and algorithms offered by VAL or its Affiliates can direct the entry of all orders entered into the Conditional Session.
Conditional Orders rest in the Conditional Session but are not firm or executable. VAL transmits In-bound Retail Orders as IOC Orders. VAL and its Affiliates' algorithms can also transmit IOC orders. VAL or its Affiliate's algorithms also transmit Conditional Orders.
When contra-side conditional orders reside in the Conditional Session or when one or more Conditional Orders and a contra-side IOC order reside in the Conditional Session such that there is a potential matching opportunity, MatchIt will send an invitation to Firm-Up to the algorithm that entered a Conditional Order. When multiple Conditional Orders are present on the same side, MatchIt will transmit the invitation to Firm-Up to one Conditional Order based on price, size, and time priority. For an execution to occur, the algorithm that has entered a Conditional Order and received an invitation to Firm-Up must respond to the invitation by transmitting an automated Firm-Up Response Order.
MatchIt will transmit an invitation to Firm-Up that contains the number of shares that are potentially available for execution and a response time within which the Firm-Up Response Order must be received for an execution to occur. The response time will be in a range of single digit to hundreds of milliseconds. The algorithm receiving an invitation to Firm-Up may then respond by sending a Firm-Up Response Order that references the invitation and matches the attributes of the invitation in terms of symbol, side and quantity. A Firm-Up Response Order may be transmitted with a quantity less than the invited quantity. An execution will occur to the extent that a Firm-Up Response Order is received by MatchIt within the designated response time.
MatchIt will only execute IOC orders against contra-side Firm-Up Response Orders. A Firm-Up Response Order to buy and a Firm-Up Response Order to sell may be executed against one another. Firm-Up Response Orders will only interact with the specific contra-side orders that caused MatchIt to transmit the invitation to Firm-Up.
When multiple conditional orders are resting in the Conditional Session, MatchIt will send an invitation to Firm-up to one algorithm that placed the Conditional Order based upon price, size, and time priority. IOC orders interact based on time priority. MatchIt will utilize any limit price, Peg and Peg Offset instructions when determining price. IOC Orders and Firm-Up Response Orders that result from Conditional Orders that cause an invitation sequence to begin are considered removal orders and receive price improvement, i.e., resting orders pay any additional portion of the spread to the extent the price or peg instructions of the contra side orders overlap.</taPart3Item9aMsgUsgDtls>

      <taPart3Item11aStrucOfNmsStk>MatchIt is an electronic crossing system that does not display orders and executes all orders at or within the NBBO as determined by VAL's Market Data Systems. MatchIt consists of the Main Session, the Conditional Session, and Hosted Sessions, which operate independently of each other. VAL business units, VAL Affiliates and Direct Subscribers enter or direct the entry of orders into the Main Session. The Main Session employs a price, time priority crossing methodology. VAL business units and VAL Affiliates enter orders and conditional interests into the Conditional Session. The Conditional Session employs a price, size, time priority crossing methodology. Hosted Sessions have the same trading services, facilities, and rules as the Main Session, and are only available to VAL business units and VAL Affiliates.  Within a single Hosted Session, VAL or VAL Affiliates will direct the orders of a single Indirect Subscriber and principal orders of its market making business units for potential crossing.  All NMS securities listed on a national securities exchange are eligible for trading in MatchIt, except MatchIt does not make Virtu Financial, Inc., symbol VIRT, available for trading, and may, in its sole discretion, stop trading certain symbols from time to time for, among other reasons, the purpose of remaining below the volume thresholds for (i) classification as an "SCI Entity" under Regulation SCI and (ii) certain regulatory requirements as set forth in Rules 301(b)(3) and (5) of Regulation ATS.</taPart3Item11aStrucOfNmsStk>

      <taPart3Item11cRulsProcsOfNmsStk>Main and Hosted Sessions:  MatchIt will execute Peg and Day orders against eligible contra-side IOC, Day and Peg 
orders.  For Peg and Day orders, priority is determined on a price, time basis. If a Subscriber modifies 
the terms of a previously transmitted order, the order will receive a new order time for matching 
purposes (i.e. the order will lose queue spot).  The only exception is a reduction in order quantity 
which, absent any other changes to the terms of the order, will not update the order time for matching 
purposes.  For IOC orders priority is based on a first in time basis.  
Removers receive price improvement.  In the case of an IOC order, the IOC order is always the 
removing order.  In the case of two Peg and/or Day orders, the second in time is the removing order.  
  
Conditional Session: The MatchIt Conditional Session accepts Conditional Orders and IOC orders.  
Conditional Orders rest in the Conditional Session but are not firm or executable.  MatchIt will send an 
invitation to Firm-Up to the algorithm that entered a Conditional Order when a potential matching 
opportunity exists. When multiple Conditional Orders are present the invitation to Firm-Up will be 
transmitted to one Conditional Order based on price, size, time, priority.  For an execution to occur, the 
algorithm that has entered a Conditional Order and received an invitation to Firm-Up must respond to the 
invitation by transmitting an automated Firm-Up Response Order.  

MatchIt will transmit an invitation to Firm-Up that contains the number of shares that are potentially 
available for execution and a response time within which the Firm-Up order must be received for an 
execution to occur.  The response time will be in a range of single digit to hundreds of milliseconds.  The 
algorithm receiving an invitation to Firm-Up may then respond by sending a Firm-Up Response Order 
that references the invitation and matches the attributes of the invitation in terms of symbol, side and 
quantity. A Firm-Up Response order may be transmitted with a quantity less than the invited quantity.  
An execution will occur to the extent that Firm-Up Response Orders are received by MatchIt within the 
designated response time.

IOC orders may only be executed against contra-side Firm-Up Response Orders. A Firm?Up Response 
Order to buy and a Firm-Up Response Order to sell may be executed against one another. Firm-Up 
Response Orders will only interact with the specific contra-side orders that caused MatchIt to transmit 
the invitation to Firm-Up.

MatchIt will send invite messages to systems that have transmitted eligible Conditional Orders based 
upon price, size, and time priority when multiple Conditional Orders are present. IOC orders interact 
based on time priority. MatchIt will utilize any limit price, Peg and Peg Offset instructions when 
determining price. IOC Orders and Firm-Up Response Orders that result from Conditional Orders that 
cause an invitation sequence to begin are considered removal orders and receive price improvement, i.e. 
resting orders pay any additional portion of the spread to the extent the price or peg instructions of the 
contra side orders overlap.

If a Subscriber modifies the terms of a previously transmitted order, the order will receive a new order 
time for matching purposes (i.e. the order will lose queue spot).  The only exception is a reduction in 
order quantity which, absent any other changes to the terms of the order, will not update the order time 
for matching purposes.  For IOC orders priority is based on a first in time basis.  
In the case of an IOC order matching against a Conditional Order, the Conditional Order is always the 
liquidity adding order.  In the case of Conditional Orders, the first in time is the liquidity adding order.  
For adders that have entered short sell Market Peg order instructions in securities subject to a Reg 
SHO Rule 201 price restriction, the adding order will receive a de minimis amount of price 
improvement of $0.0001, such that the execution price is compliant with the Reg SHO price 
restriction.  However, if the order has a price restriction that would prevent it from receiving an 
execution above the NBB then no execution will occur. 

All Sessions: 

Locked and Crossed Markets: MatchIt does not execute in a crossed market, but will execute in a 
locked market.  Subscribers have the option of not executing in a locked market on an order by order 
basis. 

Errors and Accommodations:  MatchIt reserves the right to review any transaction based upon the 
request of a Subscriber or on its own motion and declare any transaction executed by MatchIt null and 
void in the event that the transaction occurred at a price that was within the numerical guidelines for 
erroneous transactions of any exchange or was the result of a significant systems disruption.  In reviewing 
transactions resulting from significant systems disruptions, in addition to the price of the transactions, 
MatchIt may also take into account the volume of transactions as compared to the normal volume of 
transactions for the relevant security as executed by MatchIt.  MatchIt reserves the right to use its 
discretion to provide price accommodations in circumstances that are not clearly errors or erroneous 
transactions but where the circumstances are appropriate, such as minor systems latency, to make a price 
adjustment as an accommodation to an effected client(s).    

Price Protection: There are no Price Protection mechanisms.

Short Sales: Subscribers are required to mark short sale orders as ?sell short? or ?sell short exempt?.  For 
adders that have entered short sell Market Peg order instructions in securities subject to a Reg SHO Rule 
201 price restriction, the adding order will receive a de minimis amount of price improvement of $0.0001, 
such that the execution price is compliant with the Reg SHO price restriction, unless the amount of price 
improvement would exceed any limit price placed on the order.</taPart3Item11cRulsProcsOfNmsStk>

        <taPart3Item13aSegProcdurDtls>There is no segmentation in the Conditional Session and in the Hosted Sessions. In the Main Session, VAL segments Direct Subscribers into five distinct Liquidity Profiles based upon their removal orders. Direct Subscribers may enter instructions that when present on liquidity adding orders will prevent interaction with liquidity taking orders from Subscribers who fall into specified Liquidity Profiles. VAL scores and segments Direct Subscribers at the MPID level. VAL and its Affiliates' own MPIDs are scored and segmented. VAL does not score and segment Indirect Subscribers. To the extent that VAL, its Affiliates or Direct Subscriber's transmit the orders of multiple Indirect Subscribers through a single MPID, the Liquidity Profile will be the composite of all of the Indirect Subscribers. An exception is that VAL permits Direct Subscribers to have different order flows scored independently based upon a Segment ID FIX tag. The Current MatchIt FIX Specification Document provides Direct Subscribers the ability to use up to four Segment IDs labeled Segment 1, Segment 2, Segment 3 and Segment 4. 
VAL uses a scoring methodology to determine a Subscriber's Liquidity Profiles that is derived from the price move of a stock from the midpoint price at the time of fill to a weighted average of midpoint prices of various durations after the time of fill, divided by the stock's spread (a "mark out"). Only a Subscriber's removal flow (IOC orders and Day orders that remove liquidity) are included in the Liquidity Profile computation. Liquidity Profiles are generated monthly, based on the prior 3 months of trading activity. There is no de minimis volume rule in the Liquidity Profile generation.
VAL creates Liquidity Profiles by sorting Subscribers by their mark-out score. The five Liquidity Profile tiers are called Highest, High, Neutral, Low, and Lowest, where the Highest Liquidity Profile contains Subscribers who exhibit the lowest mark outs relative to other Subscribers' taking flow, and the Lowest Liquidity Profile contains Subscribers who exhibit the largest mark outs (in the Subscribers favor) relative to other Subscribers' taking flow. The Liquidity Profiles are constructed such that approximately 40% of the taking share volume is placed into the Highest category, 20% of the taking share volume is placed in the High category, 20% of the taking share volume is placed in the Neutral category, 10% of the taking share volume is placed in the Low category, and 10% of the taking share volume is placed in the Lowest category. The percentages are approximations. Based on the mix of Subscribers' share volume, they may not perfectly fit into a quintile such that the percentages are exact. MatchIt will use its discretion in these circumstances and typically will elect to include more Subscribers in a higher quintile. Subscribers that rest Day orders in MatchIt can elect to prevent various combinations of the quintiles from interacting with their resting orders on an order by order basis via FIX tag. VAL uses its own discretion to place new Subscribers into a quintile. Quintile selection for new Subscribers is based on VAL's subjective judgment of the trading and investment process employed by the new Subscriber. VAL reserves the right to move a Subscriber's liquidity profile bucket intra-month if that Subscriber's mark outs during the month deviate widely from prior trading activity. 
Direct Subscribers who add liquidity can block any of the liquidity profile buckets from interacting with their add flow. As an example, if a Subscriber specifies that their Day order only interact with the Highest Liquidity Profile, then any contra-side removal flow that is not from a Subscriber designated as Highest will not interact with the resting Day order. Liquidity removal orders may be blocked from interacting with resting orders based on the adding Subscriber's preferences. Liquidity removal orders cannot specify Liquidity Profile blocking. If a liquidity removal order includes a Liquidity Profile blocking 
instruction, the order will still be accepted, but the blocking instruction will be ignored. Other than what has been described, no other order interaction is effected by the Liquidity Profile designation of a particular Subscriber.
Liquidity Profiles only apply to order interaction in the Main Session and have no influence on order interaction in the Conditional Session and in the Hosted Sessions.</taPart3Item13aSegProcdurDtls>

This instruction is not available to Direct Subscribers. See Part III, Item 7 which lists order instructions including this instruction. 
MatchIt Liquidity Profile Interaction: All Direct Subscribers have the option to block interaction against specific Liquidity Profiles, as described in Part III, Item 13. VAL programs its algorithms to use blocking when analysis suggests it may improve execution outcomes. VAL implements the logic of the algorithms such that decisions are made on specific child orders in specific circumstances. Indirect Subscribers cannot make decisions to block based on Liquidity Profiles. MatchIt will prevent liquidity removing orders from matching with liquidity adding orders from counterparties falling into the specified liquidity profiles when Subscribers place the blocking instruction on their liquidity adding orders. Subscribers can send instructions designating which Liquidity Profiles to interact with on an order by order basis via FIX tag. These Profiles are only created for the Main Session and only effect counterparty interaction in the Main Session. See Part III, Item 7 which lists order instructions including this instruction. 
Self-Match Prevention: Direct and Indirect Subscribers may provide instructions that will prevent orders from crossing if the resulting cross may result in a transaction with no change in beneficial ownership.
Other Order Attributes: Direct Subscribers can place other attributes on orders that could limit an order's ability to interact with certain contra side interest. These additional attributes include: Minimum Execution Quantity, Do Not Execute In A Locked Market, and Add Only.

Hosted Sessions

At the request of an indirect subscriber and at VAL's discretion, VAL may establish one or more Hosted Sessions in which only VAL and its affiliates may direct orders. Each Hosted Session is arranged by VAL to facilitate interaction between VAL's VCMM and VPMM business units and a designated Indirect Subscriber of VAL's VET business unit. The VCMM and VPMM business units will transmit principal orders to interact with the order flow of such designated Indirect Subscriber. See Part II, Items 1a and 3a for more detail on Virtu's Business Units and Indirect Subscribers.  All subscribers participating in a specific Hosted Session know the identities of the other Subscribers in the Hosted Session, which includes the VCMM and VPMM business units knowing the identity of the Indirect Subscriber in the Hosted Session.

Hosted Sessions are not available to Direct Subscribers of MatchIt.  Hosted Sessions have the same matching logic, order priority, rules, and order types and attributes as the MatchIt Main Session.  See Part III Item 7a and Part III Item 11 for more detail on the Main Session's order types and attributes, trading services, facilities, and rules.  Orders directed to a Hosted Session do not interact with the MatchIt Main Session, the MatchIt Conditional Session, or any other Hosted Session.

      <taPart3Item19aSrvcUsgFees>MatchIt does not charge any subscription or connectivity fees. Direct Subscribers pay fees between $.0001 and $.0010 per share. VAL and VAL Affiliates are not assessed a fee for MatchIt trades. Indirect Subscribers pay bundled fees, See Section III, Item 19(b). VAL will consider a number of factors in determining the fee an individual Subscriber will be assessed, including, but not limited to, the client's overall relationship with VAL, the type of trading flow, the amount of trading flow, and the markets that will be traded.

VAL is assessed certain Consolidated Audit Trail (CAT) regulatory fees relating to trading on MatchIt as an execution venue. In each transaction that does not include VAL mpids VIRT and VALX, VAL is identified on transaction reports as the CAT executing broker for the buyer and the selling MatchIt subscriber is reported as the CAT executing broker for the seller.  FINRA assesses CAT fees on both VAL, on behalf of the buying MatchIt subscriber, and on the selling MatchIt subscriber. VAL passes through to the buying MatchIt subscriber these CAT-related fees that VAL is assessed on behalf of those buying MatchIt subscribers.  For transactions that include VAL mpids VIRT or VALX and an external subscriber as the contra, the external subscriber's mpid is reported as the CAT executing broker regardless of the side of the external subscriber's trade.  VAL does not pass through CAT-related fees if the MatchIt subscriber's CAT-related fees are less than $50 for a given month.  </taPart3Item19aSrvcUsgFees>
      <taPart3Item19bBundldSrvcUsgFees>VAL establishes fees for use of its execution products and services, which could include executions in MatchIt, on an individual client basis.

Client specific clearing arrangements, as specified in Section III, Item 22, are not considered when establishing a fee for that client. VAL will consider a number of factors in determining whether an Indirect Subscriber can access orders designated as Inbound Retail including, but not limited to, the overall commission rates an Indirect Subscriber pays to the Firm, the client's overall relationship with the Firm, the type of trading flow, and the amount of trading flow. Use of Hosted Sessions would not require subscribers to pay additional fees. </taPart3Item19bBundldSrvcUsgFees>
      <taPart3Item19cRbtDiscOfFees>MatchIt may pay the cost of cross connects for Direct Subscribers to connect to the NY 5 Hub based upon the overall relationship with the client and or the perceived value of having the Subscriber enter or direct the entry of orders to MatchIt.</taPart3Item19cRbtDiscOfFees>
      <taPart3Item20aSuspndProcdur>VAL may in its sole discretion, stop trading certain symbols from time to time for, among other reasons, the purpose of remaining below the volume thresholds for (i) classification as an "SCI Entity" under Regulation SCI and (ii) certain regulatory requirements as set forth in Rules 301(b)(3) and (5) of Regulation ATS.
VAL uses a proprietary market data system to consolidate the best bids and offers to determine the NBBO at which executions occur on MatchIt. See Part III, Item 23 for a description of this system. VAL has programmed its market data system to disseminate an alert when it detects a certain level of disparity from normative messages received by the systems. The MatchIt system is programmed to shift to utilizing only the SIP BBOs when there is a certain level of disparity between the exchange book feeds and the SIP. If the Firm's Core Operations staff determines that there appears to be a significant delay or issue with the Firm's market data, they will cause MatchIt to suspend trading in the impacted symbol or in all symbols in the case that they determine there is a more severe systems issue. In either event, the Core Operations staff will cause MatchIt to cancel impacted orders. Cancellation reports will be sent to clients as soon as possible and MatchIt's client services personnel will attempt to contact Subscribers. Where there is a severe systems interruption that prevents MatchIt from recovering for the remainder of the day, MatchIt will instruct Subscribers to route their orders to other market centers. 
MatchIt will not execute orders if the NBBO is crossed, if the NBB is below the LULD Lower Limit Price Band, if the NBO is above the LULD Upper Limit Price Band, or if the security is in a LULD Trading Pause.
MatchIt will reject orders in certain NMS Stocks, including any symbols on VAL's restricted list or symbols for which VAL seeks to remain below certain volume thresholds. In those circumstances MatchIt will provide clients with notice of the symbol(s) that will be unavailable by posting information on the MatchIt page on the Virtu Financial, Inc. website (http://www.virtu.com).

VAL requires Direct Subscribers to be self-clearing or have an arrangement with a clearing firm. VAL submits all transactions of Direct Subscribers to NSCC for clearance and NSCC submits entries to DTC for settlement. Direct Subscribers may elect to clear their transactions via a QSR agreement which allows for VAL to submit a locked in trade to NSCC for clearance or via an AGU Agreement which allows VAL to submit locked in trades to the FINRA NASDAQ Carteret or NASDAQ Chicago TRF for submission to NSCC for clearance. VAL submit transactions for clearance and settlement trades with Indirect Subscriber's that are broker-dealers in the same manner as described above.

      <taPart3Item23aMrktDatSrc>MatchIt employs a proprietary market data system that uses a combination of direct market data feeds from exchanges and market data disseminated by the Securities Information Processors (SIP) to determine the NBBO. Specifically, MatchIt uses direct market data for all exchanges other than LTSE, for which the SIP is used as LTSE does not offer direct market data feeds. MatchIt utilizes this proprietary system to price, prioritize, and match orders in the Main Session, Conditional Session, and Hosted Sessions in compliance with regulations, including Reg NMS and Reg SHO. 

SIP data is used as a backup feed, and is used in place of a direct feed from a particular exchange if that exchange is experiencing a technical issue. Switching to the SIP data feed is done via an automated process that compares direct feed data to SIP data. Additionally, Core Operations have the ability to switch to the SIP data feed on a discretionary basis. Switching back to direct feed data from the SIP data feed is done purely on a discretionary basis, and is performed by the Core Operations team once this team has confirmed that direct feed data in question is correct. The SIP data feed is also used for regulatory items, including limit up/limit down bands, trading halts, and Reg SHO designations.</taPart3Item23aMrktDatSrc>
