General Description of Registrant [Abstract]                        
Investment Objectives and Practices [Text Block]

The Fund’s investment objective is to seek current income and attractive total return. The Fund seeks to achieve its investment objective by investing globally in high-conviction opportunities across Oaktree’s performing credit platform of high-yield bonds, senior loans, structured credit, emerging markets debt and convertibles, inclusive of both public and private credit sectors. High-yield bonds are also referred to as “below-investment grade rated securities” or “junk bonds,” as described in the Fund’s Prospectus. The Fund seeks to add value through three sources: (1) providing exposure to asset classes that require specialized expertise; (2) performing well in each asset class through proprietary, bottom-up and credit research; and (3) allocating capital opportunistically among asset classes based on Oaktree’s assessment of relative value.

7.  Capital Shares

The Charter authorizes the Fund to issue up to 1,000,000,000 shares of common stock, $.001 par value per share, 250,000,000 of which have been classified as Class A Shares, 250,000,000 of which have been classified as Class D Shares, 250,000,000 of which have been classified as Class T Shares, and 250,000,000 of which have been classified as Class U Shares (collectively “Shares” and respectively, “Class A Shares,” “Class D Shares,” “Class T Shares” and “Class U Shares”). As of June 30, 2026, the Adviser owned 69% of the shares outstanding of Class D shares. The Board may, without any action by the shareholders, amend the Charter from time to time to increase or decrease the aggregate number of shares or the number of shares of any class or series that the Fund has authority to issue under the Charter and the 1940 Act. In addition, the Charter authorizes the Board, without any action by the shareholders, to classify and reclassify any unissued common shares and preferred stock into other classes or series of shares from time to time by setting or changing the terms, preferences, conversion or other rights, voting powers, restrictions, limitations as to distributions, qualifications and terms and conditions of

redemption for each class or series. Although the Fund has no present intention of doing so, it could issue a class or series of shares that could delay, defer or prevent a transaction or a change in control of the Fund that might otherwise be in the shareholders’ best interests. Under Maryland law, shareholders generally are not liable for the Fund’s debts or obligations.

All common shares offered will be, upon issuance, duly authorized, fully paid and nonassessable. Holders of common shares are entitled to receive distributions when authorized by the Board and declared by the Fund out of assets legally available for the payment of distributions. Holders of common shares have no preference, conversion, exchange, sinking fund, redemption or appraisal rights and have no preemptive rights to subscribe for any of the Fund’s securities. All common shares have equal distribution, liquidation and other rights. The Fund may offer multiple classes of common shares, which may be subject to differing fees and expenses. Distributions may vary among the classes as a result of the different fee structure of the classes.

                      
Security Dividends [Text Block] Holders of common shares are entitled to receive distributions when authorized by the Board and declared by the Fund out of assets legally available for the payment of distributions.                      
Security Liquidation Rights [Text Block] All common shares have equal distribution, liquidation and other rights.                      
Security Preemptive and Other Rights [Text Block] Holders of common shares have no preference, conversion, exchange, sinking fund, redemption or appraisal rights and have no preemptive rights to subscribe for any of the Fund’s securities.                      
Long Term Debt, Title [Text Block] Credit Facility                      
Long Term Debt, Dividends and Covenants [Text Block]

According to terms of the Credit Facility agreement, the Fund is required to comply with various covenants, reporting requirements and other customary requirements for similar revolving credit facilities, including, without limitation, covenants related to maintaining a ratio of total assets (less total liabilities other than senior securities representing indebtedness) to senior securities representing indebtedness of the Fund of not less than 300%. These covenants are subject to important limitations and exceptions that are described in the documents governing the Credit Facility. As of June 30, 2026, the Fund was in compliance with the terms of the Credit Facility.
