| Invesco BulletShares 2036 Corporate Bond ETF | Risk Lose Money [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | The Shares will change in value, and you could lose money by investing in the Fund. |
| Invesco BulletShares 2036 Corporate Bond ETF | Risk Nondiversified Status [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Non-Diversified Fund Risk. The Fund is non-diversified and can invest a greater portion of its assets in the obligations or securities of a small number of issuers or any single issuer than a diversified fund can. As a result, changes in the market value of a single investment could cause greater fluctuations in Share price than would occur in a diversified fund. This may increase the Fund's volatility and cause the performance of a relatively small number of issuers to have a greater impact on the Fund's performance.
|
| Invesco BulletShares 2036 Corporate Bond ETF | Market Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Market Risk. Securities in the Underlying Index are subject to market fluctuations. You should anticipate that the value of the Shares will decline, more or less, in correlation with any decline in value of the securities in the Underlying Index. Additionally, natural or environmental disasters, widespread disease or other public health issues, war, military conflicts, acts of terrorism, economic crises or other events could result in increased premiums or discounts to the Fund’s net asset value (“NAV”). Certain changes in the U.S. economy in particular, such as when the U.S. economy weakens or when its financial markets decline, may have a material adverse effect on global financial markets as a whole, and on the securities to which the Underlying Index has exposure. Increasingly strained relations between the U.S. and foreign countries, including as a result of economic sanctions and tariffs, may also adversely affect U.S. issuers, as well as non-U.S. issuers.
During a general downturn in the financial markets, multiple asset classes may decline in value. When markets perform well, there can be no assurance that specific investments held by the Underlying Index will rise in value.
|
| Invesco BulletShares 2036 Corporate Bond ETF | Index Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Index Risk. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of its Underlying Index. Therefore, the Fund would not necessarily buy or sell a security unless that security is added to or removed from, respectively, its Underlying Index, even if that security generally is underperforming. Additionally, the Fund generally rebalances its portfolio in accordance with its Underlying Index, and, therefore, any changes to its Underlying Index’s rebalance schedule will typically result in corresponding changes to the Fund’s rebalance schedule.
|
| Invesco BulletShares 2036 Corporate Bond ETF | Fixed-Income Securities Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Fixed-Income Securities Risk. Fixed-income securities are subject to interest rate risk and credit risk. Interest rate risk refers to fluctuations in the value of a fixed-income security resulting from changes in the general level of interest rates. When the general level of interest rates goes up, the prices of most fixed-income securities go down. When the general level of interest rates goes down, the prices of most fixed-income securities go up. Fixed-income securities with longer maturities typically are more sensitive to changes in interest rates, making them more volatile than securities with shorter maturities. Credit risk refers to the possibility that the issuer of a security will be unable and/or unwilling to make timely interest payments and/or repay the principal on its debt. Debt instruments are subject to varying degrees of credit risk, which may be reflected in credit ratings. There is a possibility that the credit rating of a fixed-income security may be downgraded after purchase, which may occur quickly and without advance warning following sudden market downturns or unexpected developments involving an issuer, and which may adversely affect the liquidity and value of the security.
|
| Invesco BulletShares 2036 Corporate Bond ETF | Foreign Fixed-Income Investment Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Foreign Fixed-Income Investment Risk. Investments in fixed-income securities of non-U.S. issuers are subject to the same risks as other debt securities, notably credit risk, market risk, interest rate risk and liquidity risk, while also facing risks beyond those associated with investments in U.S. securities. For example, foreign securities may have relatively low market liquidity, greater market volatility, decreased publicly available information, and less reliable financial information about issuers, and inconsistent and potentially less stringent accounting, auditing and financial reporting requirements and standards of practice, including recordkeeping standards, comparable to those applicable to domestic issuers. Foreign securities also are subject to the risks of expropriation, nationalization, political instability or other adverse political or economic developments and the difficulty of enforcing obligations in other countries. Investments in foreign securities also may be subject to dividend withholding or confiscatory taxes, currency blockage and/or transfer restrictions and higher transactional costs.
|
| Invesco BulletShares 2036 Corporate Bond ETF | Changing Fixed-Income Market Conditions Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Changing Fixed-Income Market Conditions Risk. Increases in the federal funds and equivalent foreign rates or other changes to monetary policy or regulatory actions may expose fixed-income markets to heightened volatility, perhaps suddenly and to a significant degree, and to reduced liquidity for certain fixed-income investments, particularly those with longer maturities. Such changes and resulting increased volatility may adversely impact the Fund, including its operations and return potential. It is difficult to predict the impact of interest rate changes on various markets. In addition, decreases in fixed-income dealer market-making capacity may also potentially lead to heightened volatility and reduced liquidity in the fixed-income markets. As a result, the value of the Fund’s investments and share price may decline. Changes in central bank policies and other governmental actions and political events within the U.S. and abroad may also, among other things, affect investor and consumer expectations and confidence in the financial markets, which could result in higher than normal redemptions by APs (as defined herein), which could potentially increase the Fund’s portfolio turnover rate and transaction costs.
|
| Invesco BulletShares 2036 Corporate Bond ETF | Industry Concentration Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Industry Concentration Risk. In following its methodology, the Underlying Index from time to time may be concentrated to a significant degree in securities of issuers operating in a single industry or industry group. To the extent that the Underlying Index concentrates in the securities of issuers in a particular industry or industry group, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in an industry or industry group, the Fund may face more risks than if it were diversified broadly over numerous industries or industry groups. Such industry-based risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, the following: general economic conditions or cyclical market patterns that could negatively affect supply and demand in a particular industry; competition for resources; adverse labor relations; political or world events; obsolescence of technologies; and increased competition or new product introductions that may affect the profitability or viability of companies in an industry. In addition, at times, such industry or industry group may be out of favor and underperform other industries or the market as a whole.
|
| Invesco BulletShares 2036 Corporate Bond ETF | Fluctuation of Yield and Liquidation Amount Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Fluctuation of Yield and Liquidation Amount Risk. The Fund, unlike a direct investment in a bond that has a level coupon payment and a fixed payment at maturity, will make distributions of income that vary over time. Unlike a direct investment in bonds, the breakdown of returns between Fund distributions and liquidation proceeds are not predictable at the time of your investment. For example, at times during the Fund’s existence, it may make distributions at a greater (or lesser) rate than the coupon payments received on the Fund’s portfolio, which will result in the Fund returning a lesser (or greater) amount on liquidation than would otherwise be the case. The rate of Fund distribution payments may adversely affect the tax characterization of your returns from an investment in the Fund relative to a direct investment in bonds. If the amount you receive as liquidation proceeds upon the Fund’s termination is higher or lower than your cost basis, you may experience a gain or loss for tax purposes.
|
| Invesco BulletShares 2036 Corporate Bond ETF | Call Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Call Risk. If interest rates fall, it is possible that issuers of callable securities with high interest coupons will “call” (or prepay) their bonds before their maturity date. If an issuer exercises such a call during a period of declining interest rates, the Fund may have to replace such called security with a lower yielding security. If that were to happen, the Fund’s net investment income could fall.
|
| Invesco BulletShares 2036 Corporate Bond ETF | Extension Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Extension Risk. Extension risk is the opposite of reinvestment risk, and typically occurs when interest rates rise, thereby causing repayments of fixed-income securities to occur more slowly than expected by the market. This may drive the prices of these securities down because their interest rates are lower than the current interest rate and they have longer duration (resulting in increased sensitivity to interest rate changes).
|
| Invesco BulletShares 2036 Corporate Bond ETF | Reinvestment Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Reinvestment Risk. Reinvestment risk is the risk that the Fund will not be able to reinvest income or principal at the same return it is currently earning. Reinvestment risk is greater during periods of declining interest rates, as prepayments often occur faster. It is related to call risk, since issuers of callable securities with high interest coupons may call their bonds before their maturity date. This may require the Fund to reinvest the proceeds at an earlier date, and it may be able to do so only at lower yields, thereby reducing its return.
|
| Invesco BulletShares 2036 Corporate Bond ETF | Liquidity Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Liquidity Risk. Liquidity risk exists when a particular investment is difficult to purchase or sell. If the Fund invests in illiquid securities or current portfolio securities become illiquid, it may reduce the returns of the Fund because the Fund may be unable to sell the illiquid securities at an advantageous time or price.
|
| Invesco BulletShares 2036 Corporate Bond ETF | Declining Yield Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Declining Yield Risk. During the final year of the Fund's operations, as the bonds held by the Fund mature and the Fund's portfolio transitions to cash and cash equivalents, the Fund's yield will generally tend to move toward the yield of cash and cash equivalents and thus may be lower than the yields of the bonds previously held by the Fund and/or prevailing yields for bonds in the market.
|
| Invesco BulletShares 2036 Corporate Bond ETF | Issuer-Specific Changes Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Issuer-Specific Changes Risk. The performance of the Fund depends on the performance of individual securities to which the Fund has exposure. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform worse than the market as a whole, causing the value of the Fund’s securities to decline.
|
| Invesco BulletShares 2036 Corporate Bond ETF | Valuation Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Valuation Risk. The price the Fund could receive upon the sale of a portfolio investment may differ from the Fund’s valuation of the investment, particularly for investments that trade in thin or volatile markets or that are valued using a fair valuation methodology. Financial information related to securities of non-U.S. issuers may be less reliable than information related to securities of U.S. issuers, which may make it difficult to obtain a current price for a non-U.S. security held by the Fund. When market quotations are not readily available for Fund investments, those investments are fair valued by the Adviser. There are multiple methods that can be used to fair value a portfolio investment and such methods may involve more subjectivity than the use of market quotations. The value established for an investment through fair valuation may be different from what would be produced if the investment had been valued using market quotations. In addition, there is no assurance that the Fund could sell a portfolio investment at any time for the value ascribed to it for purposes of calculating the Fund’s net asset value, and it is possible that the Fund could incur a loss because an investment is sold at a discount to its ascribed value. The ability to value investments may also be impacted by technological issues and/or errors by pricing services or other third-party service providers.
|
| Invesco BulletShares 2036 Corporate Bond ETF | Valuation Time Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Valuation Time Risk. Because foreign exchanges may be open on days when the Fund does not price its Shares, the value of the non-U.S. securities in the Fund’s portfolio may change on days when investors will not be able to purchase or sell the Fund’s Shares. As a result, trading spreads and the resulting premium or discount on the Fund’s Shares may widen, and, therefore, increase the difference between the market price of the Fund’s Shares and the NAV of such Shares.
|
| Invesco BulletShares 2036 Corporate Bond ETF | Sampling Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Sampling Risk. The Fund's use of a representative sampling methodology may result in it holding a smaller number of securities than are in the Underlying Index. As a result, an adverse development with respect to an issuer of securities held by the Fund could result in a greater decline in NAV than would be the case if the Fund held all of the securities in the Underlying Index. To the extent the assets in the Fund are smaller, these risks will be greater.
|
| Invesco BulletShares 2036 Corporate Bond ETF | Non-Correlation Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Non-Correlation Risk. The Fund's return may not match the return of the Underlying Index for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund's securities holdings to reflect changes in the Underlying Index. Additionally, the Fund’s use of a representative sampling methodology may cause the Fund not to be as well-correlated with the return of the Underlying Index as would be the case if the Fund purchased all of the securities in the Underlying Index in the proportions represented in the Underlying Index. In addition, the performance of the Fund and the Underlying Index may vary due to asset valuation differences and differences between the Fund's portfolio and the Underlying Index resulting from legal restrictions, costs or liquidity constraints.
|
| Invesco BulletShares 2036 Corporate Bond ETF | Authorized Participant Concentration Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Authorized Participant Concentration Risk. Only authorized participants (“APs”) may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of institutions that may act as APs and such APs have no obligation to submit creation or redemption orders. Consequently, there is no assurance that APs will establish or maintain an active trading market for the Shares. This risk may be heightened to the extent that securities held by the Fund are traded outside a collateralized settlement system. In that case, APs may be required to post collateral on certain trades on an agency basis (i.e., on behalf of other market participants), which only a limited number of APs may be able to do. In addition, to the extent that APs exit the business or are unable to proceed with creation and/or redemption orders with respect to the Fund and no other AP is able to step forward to create or redeem Creation Units (as defined below), this may result in a significantly diminished trading market for Shares, and Shares may be more likely to trade at a premium or discount to the Fund's NAV and to face trading halts and/or delisting. Additionally, to the extent that the Fund holds non-U.S. securities, such securities may have lower trading volumes or could experience extended market closures or trading halts. To the extent that the Fund invests in non-U.S. securities, it may face increased risks that APs may not be able to effectively create or redeem Creation Units, or that the Shares may be halted and/or delisted.
|
| Invesco BulletShares 2036 Corporate Bond ETF | Market Trading Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for the Shares, losses from trading in secondary markets, periods of high volatility, and disruption in the creation/redemption process of the Fund. In stressed market conditions, the market for Shares may become less liquid in response to deteriorating liquidity in the markets for the Fund’s portfolio holdings, which may cause a variance in the market price of Shares and their underlying NAV. In addition, an exchange or market may issue trading halts on specific securities or financial instruments. As a result, the ability to trade certain securities or financial instruments may be restricted, which may disrupt the Fund’s creation/redemption process, potentially affect the price at which Shares trade in the secondary market, and/or result in the Fund being unable to trade certain securities or financial instruments at all. In these circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and/or may incur substantial trading losses. Any of these factors may lead to the Shares trading at a premium or discount to the Fund's NAV.
|
| Invesco BulletShares 2036 Corporate Bond ETF | Operational Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Operational Risk. The Fund is exposed to operational risks arising from a number of factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund and the Adviser seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address these risks.
|
| Invesco BulletShares 2036 Corporate Bond ETF | Shares May Trade at Prices Different than NAV [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Shares May Trade at Prices Different than NAV. Shares trade on a stock exchange at prices at, above or below the Fund’s most recent NAV. The Fund’s NAV is calculated at the end of each business day and fluctuates with changes in the market value of the Fund’s holdings. The trading price of the Shares fluctuates continuously throughout trading hours on the exchange, based on both the relative market supply of, and demand for, the Shares and the underlying value of the Fund’s portfolio holdings. As a result, the trading prices of the Shares may deviate from the Fund’s NAV. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV.
|
| Invesco BulletShares 2034 High Yield Corporate Bond ETF | Risk Lose Money [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | The Shares will change in value, and you could lose money by investing in the Fund. |
| Invesco BulletShares 2034 High Yield Corporate Bond ETF | Risk Nondiversified Status [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Non-Diversified Fund Risk. The Fund is non-diversified and can invest a greater portion of its assets in the obligations or securities of a small number of issuers or any single issuer than a diversified fund can. As a result, changes in the market value of a single investment could cause greater fluctuations in Share price than would occur in a diversified fund. This may increase the Fund's volatility and cause the performance of a relatively small number of issuers to have a greater impact on the Fund's performance.
|
| Invesco BulletShares 2034 High Yield Corporate Bond ETF | Market Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Market Risk. Securities in the Underlying Index are subject to market fluctuations. You should anticipate that the value of the Shares will decline, more or less, in correlation with any decline in value of the securities in the Underlying Index. Additionally, natural or environmental disasters, widespread disease or other public health issues, war, military conflicts, acts of terrorism, economic crises or other events could result in increased premiums or discounts to the Fund’s net asset value (“NAV”). Certain changes in the U.S. economy in particular, such as when the U.S. economy weakens or when its financial markets decline, may have a material adverse effect on global financial markets as a whole, and on the securities to which the Underlying Index has exposure. Increasingly strained relations between the U.S. and foreign countries, including as a result of economic sanctions and tariffs, may also adversely affect U.S. issuers, as well as non-U.S. issuers.
During a general downturn in the financial markets, multiple asset classes may decline in value. When markets perform well, there can be no assurance that specific investments held by the Underlying Index will rise in value.
|
| Invesco BulletShares 2034 High Yield Corporate Bond ETF | Index Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Index Risk. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of its Underlying Index. Therefore, the Fund would not necessarily buy or sell a security unless that security is added to or removed from, respectively, its Underlying Index, even if that security generally is underperforming. Additionally, the Fund generally rebalances its portfolio in accordance with its Underlying Index, and, therefore, any changes to its Underlying Index’s rebalance schedule will typically result in corresponding changes to the Fund’s rebalance schedule.
|
| Invesco BulletShares 2034 High Yield Corporate Bond ETF | Fixed-Income Securities Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Fixed-Income Securities Risk. Fixed-income securities are subject to interest rate risk and credit risk. Interest rate risk refers to fluctuations in the value of a fixed-income security resulting from changes in the general level of interest rates. When the general level of interest rates goes up, the prices of most fixed-income securities go down. When the general level of interest rates goes down, the prices of most fixed-income securities go up. Fixed-income securities with longer maturities typically are more sensitive to changes in interest rates, making them more volatile than securities with shorter maturities. Credit risk refers to the possibility that the issuer of a security will be unable and/or unwilling to make timely interest payments and/or repay the principal on its debt. Debt instruments are subject to varying degrees of credit risk, which may be reflected in credit ratings. There is a possibility that the credit rating of a fixed-income security may be downgraded after purchase, which may occur quickly and without advance warning following sudden market downturns or unexpected developments involving an issuer, and which may adversely affect the liquidity and value of the security.
|
| Invesco BulletShares 2034 High Yield Corporate Bond ETF | Non-Investment Grade Securities Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Non-Investment Grade Securities Risk. Non-investment grade securities (commonly known as “junk bonds” or “high yield bonds”) and unrated securities of comparable credit quality are considered speculative and are subject to the increased risk of an issuer’s inability to meet principal and interest payment obligations. These securities may be subject to greater price volatility due to such factors as specific corporate developments, interest rate sensitivity, negative perceptions of the non-investment grade securities markets generally, real or perceived adverse economic and competitive industry conditions and less secondary market liquidity. If the issuer of non-investment grade securities defaults, the Fund may incur additional expenses to seek recovery.
|
| Invesco BulletShares 2034 High Yield Corporate Bond ETF | Foreign Fixed-Income Investment Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Foreign Fixed-Income Investment Risk. Investments in fixed-income securities of non-U.S. issuers are subject to the same risks as other debt securities, notably credit risk, market risk, interest rate risk and liquidity risk, while also facing risks beyond those associated with investments in U.S. securities. For example, foreign securities may have relatively low market liquidity, greater market volatility, decreased publicly available information, and less reliable financial information about issuers, and inconsistent and potentially less stringent accounting, auditing and financial reporting requirements and standards of practice, including recordkeeping standards, comparable to those applicable to domestic issuers. Foreign securities also are subject to the risks of expropriation, nationalization, political instability or other adverse political or economic developments and the difficulty of enforcing obligations in other countries. Investments in foreign securities also may be subject to dividend withholding or confiscatory taxes, currency blockage and/or transfer restrictions and higher transactional costs.
|
| Invesco BulletShares 2034 High Yield Corporate Bond ETF | Changing Fixed-Income Market Conditions Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Changing Fixed-Income Market Conditions Risk. Increases in the federal funds and equivalent foreign rates or other changes to monetary policy or regulatory actions may expose fixed-income markets to heightened volatility, perhaps suddenly and to a significant degree, and to reduced liquidity for certain fixed-income investments, particularly those with longer maturities. Such changes and resulting increased volatility may adversely impact the Fund, including its operations and return potential. It is difficult to predict the impact of interest rate changes on various markets. In addition, decreases in fixed-income dealer market-making capacity may also potentially lead to heightened volatility and reduced liquidity in the fixed-income markets. As a result, the value of the Fund’s investments and share price may decline. Changes in central bank policies and other governmental actions and political events within the U.S. and abroad may also, among other things, affect investor and consumer expectations and confidence in the financial markets, which could result in higher than normal redemptions by APs (as defined herein), which could potentially increase the Fund’s portfolio turnover rate and transaction costs.
|
| Invesco BulletShares 2034 High Yield Corporate Bond ETF | Industry Concentration Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Industry Concentration Risk. In following its methodology, the Underlying Index from time to time may be concentrated to a significant degree in securities of issuers operating in a single industry or industry group. To the extent that the Underlying Index concentrates in the securities of issuers in a particular industry or industry group, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in an industry or industry group, the Fund may face more risks than if it were diversified broadly over numerous industries or industry groups. Such industry-based risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, the following: general economic conditions or cyclical market patterns that could negatively affect supply and demand in a particular industry; competition for resources; adverse labor relations; political or world events; obsolescence of technologies; and increased competition or new product introductions that may affect the profitability or viability of companies in an industry. In addition, at times, such industry or industry group may be out of favor and underperform other industries or the market as a whole.
|
| Invesco BulletShares 2034 High Yield Corporate Bond ETF | Rule 144A Securities Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Rule 144A Securities Risk. The Fund may invest in securities that are normally purchased or resold pursuant to Rule 144A under the Securities Act. Rule 144A securities are restricted securities that are not publicly traded. As such, Rule 144A securities may be subject to legal restrictions on resale. Rule 144A securities are generally not traded on established markets and may be illiquid, difficult to value and subject to wide fluctuations in value. Delay or difficulty in selling such securities may result in a loss to the Fund.
|
| Invesco BulletShares 2034 High Yield Corporate Bond ETF | Fluctuation of Yield and Liquidation Amount Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Fluctuation of Yield and Liquidation Amount Risk. The Fund, unlike a direct investment in a bond that has a level coupon payment and a fixed payment at maturity, will make distributions of income that vary over time. Unlike a direct investment in bonds, the breakdown of returns between Fund distributions and liquidation proceeds are not predictable at the time of your investment. For example, at times during the Fund’s existence, it may make distributions at a greater (or lesser) rate than the coupon payments received on the Fund’s portfolio, which will result in the Fund returning a lesser (or greater) amount on liquidation than would otherwise be the case. The rate of Fund distribution payments may adversely affect the tax characterization of your returns from an investment in the Fund relative to a direct investment in bonds. If the amount you receive as liquidation proceeds upon the Fund’s termination is higher or lower than your cost basis, you may experience a gain or loss for tax purposes.
|
| Invesco BulletShares 2034 High Yield Corporate Bond ETF | Call Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Call Risk. If interest rates fall, it is possible that issuers of callable securities with high interest coupons will “call” (or prepay) their bonds before their maturity date. If an issuer exercises such a call during a period of declining interest rates, the Fund may have to replace such called security with a lower yielding security. If that were to happen, the Fund’s net investment income could fall.
|
| Invesco BulletShares 2034 High Yield Corporate Bond ETF | Extension Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Extension Risk. Extension risk is the opposite of reinvestment risk, and typically occurs when interest rates rise, thereby causing repayments of fixed-income securities to occur more slowly than expected by the market. This may drive the prices of these securities down because their interest rates are lower than the current interest rate and they have longer duration (resulting in increased sensitivity to interest rate changes).
|
| Invesco BulletShares 2034 High Yield Corporate Bond ETF | Reinvestment Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Reinvestment Risk. Reinvestment risk is the risk that the Fund will not be able to reinvest income or principal at the same return it is currently earning. Reinvestment risk is greater during periods of declining interest rates, as prepayments often occur faster. It is related to call risk, since issuers of callable securities with high interest coupons may call their bonds before their maturity date. This may require the Fund to reinvest the proceeds at an earlier date, and it may be able to do so only at lower yields, thereby reducing its return.
|
| Invesco BulletShares 2034 High Yield Corporate Bond ETF | Liquidity Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Liquidity Risk. Liquidity risk exists when a particular investment is difficult to purchase or sell. If the Fund invests in illiquid securities or current portfolio securities become illiquid, it may reduce the returns of the Fund because the Fund may be unable to sell the illiquid securities at an advantageous time or price.
|
| Invesco BulletShares 2034 High Yield Corporate Bond ETF | Declining Yield Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Declining Yield Risk. During the final year of the Fund's operations, as the bonds held by the Fund mature and the Fund's portfolio transitions to cash and cash equivalents, the Fund's yield will generally tend to move toward the yield of cash and cash equivalents and thus may be lower than the yields of the bonds previously held by the Fund and/or prevailing yields for bonds in the market.
|
| Invesco BulletShares 2034 High Yield Corporate Bond ETF | Issuer-Specific Changes Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Issuer-Specific Changes Risk. The performance of the Fund depends on the performance of individual securities to which the Fund has exposure. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform worse than the market as a whole, causing the value of the Fund’s securities to decline.
|
| Invesco BulletShares 2034 High Yield Corporate Bond ETF | Valuation Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Valuation Risk. The price the Fund could receive upon the sale of a portfolio investment may differ from the Fund’s valuation of the investment, particularly for investments that trade in thin or volatile markets or that are valued using a fair valuation methodology. Financial information related to securities of non-U.S. issuers may be less reliable than information related to securities of U.S. issuers, which may make it difficult to obtain a current price for a non-U.S. security held by the Fund. When market quotations are not readily available for Fund investments, those investments are fair valued by the Adviser. There are multiple methods that can be used to fair value a portfolio investment and such methods may involve more subjectivity than the use of market quotations. The value established for an investment through fair valuation may be different from what would be produced if the investment had been valued using market quotations. In addition, there is no assurance that the Fund could sell a portfolio investment at any time for the value ascribed to it for purposes of calculating the Fund’s net asset value, and it is possible that the Fund could incur a loss because an investment is sold at a discount to its ascribed value. The ability to value investments may also be impacted by technological issues and/or errors by pricing services or other third-party service providers.

| Prospectus [Line Items] | |
| Risk [Text Block] | Valuation Time Risk. Because foreign exchanges may be open on days when the Fund does not price its Shares, the value of the non-U.S. securities in the Fund’s portfolio may change on days when investors will not be able to purchase or sell the Fund’s Shares. As a result, trading spreads and the resulting premium or discount on the Fund’s Shares may widen, and, therefore, increase the difference between the market price of the Fund’s Shares and the NAV of such Shares.

| Prospectus [Line Items] | |
| Risk [Text Block] | Sampling Risk. The Fund's use of a representative sampling methodology may result in it holding a smaller number of securities than are in the Underlying Index. As a result, an adverse development with respect to an issuer of securities held by the Fund could result in a greater decline in NAV than would be the case if the Fund held all of the securities in the Underlying Index. To the extent the assets in the Fund are smaller, these risks will be greater.

| Invesco BulletShares 2034 High Yield Corporate Bond ETF | Non-Correlation Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Non-Correlation Risk. The Fund's return may not match the return of the Underlying Index for a number of reasons. For example, the Fund incurs operating expenses not applicable to the Underlying Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund's securities holdings to reflect changes in the Underlying Index. Additionally, the Fund’s use of a representative sampling methodology may cause the Fund not to be as well-correlated with the return of the Underlying Index as would be the case if the Fund purchased all of the securities in the Underlying Index in the proportions represented in the Underlying Index. In addition, the performance of the Fund and the Underlying Index may vary due to asset valuation differences and differences between the Fund's portfolio and the Underlying Index resulting from legal restrictions, costs or liquidity constraints.

| Invesco BulletShares 2034 High Yield Corporate Bond ETF | Authorized Participant Concentration Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Authorized Participant Concentration Risk. Only authorized participants (“APs”) may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of institutions that may act as APs and such APs have no obligation to submit creation or redemption orders. Consequently, there is no assurance that APs will establish or maintain an active trading market for the Shares. This risk may be heightened to the extent that securities held by the Fund are traded outside a collateralized settlement system. In that case, APs may be required to post collateral on certain trades on an agency basis (i.e., on behalf of other market participants), which only a limited number of APs may be able to do. In addition, to the extent that APs exit the business or are unable to proceed with creation and/or redemption orders with respect to the Fund and no other AP is able to step forward to create or redeem Creation Units (as defined below), this may result in a significantly diminished trading market for Shares, and Shares may be more likely to trade at a premium or discount to the Fund's NAV and to face trading halts and/or delisting. Additionally, to the extent that the Fund holds non-U.S. securities, such securities may have lower trading volumes or could experience extended market closures or trading halts. To the extent that the Fund invests in non-U.S. securities, it may face increased risks that APs may not be able to effectively create or redeem Creation Units, or that the Shares may be halted and/or delisted.

| Invesco BulletShares 2034 High Yield Corporate Bond ETF | Market Trading Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for the Shares, losses from trading in secondary markets, periods of high volatility, and disruption in the creation/redemption process of the Fund. In stressed market conditions, the market for Shares may become less liquid in response to deteriorating liquidity in the markets for the Fund’s portfolio holdings, which may cause a variance in the market price of Shares and their underlying NAV. In addition, an exchange or market may issue trading halts on specific securities or financial instruments. As a result, the ability to trade certain securities or financial instruments may be restricted, which may disrupt the Fund’s creation/redemption process, potentially affect the price at which Shares trade in the secondary market, and/or result in the Fund being unable to trade certain securities or financial instruments at all. In these circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and/or may incur substantial trading losses. Any of these factors may lead to the Shares trading at a premium or discount to the Fund's NAV.

| Invesco BulletShares 2034 High Yield Corporate Bond ETF | Operational Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Operational Risk. The Fund is exposed to operational risks arising from a number of factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund and the Adviser seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address these risks.

| Invesco BulletShares 2034 High Yield Corporate Bond ETF | Shares May Trade at Prices Different than NAV [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Shares May Trade at Prices Different than NAV. Shares trade on a stock exchange at prices at, above or below the Fund’s most recent NAV. The Fund’s NAV is calculated at the end of each business day and fluctuates with changes in the market value of the Fund’s holdings. The trading price of the Shares fluctuates continuously throughout trading hours on the exchange, based on both the relative market supply of, and demand for, the Shares and the underlying value of the Fund’s portfolio holdings. As a result, the trading prices of the Shares may deviate from the Fund’s NAV. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV.
