| 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. | |||||

| Capital Stock [Table Text Block] | 7. Capital Shares The Fund is authorized to issue up to 1,000,000,000 shares of common stock, $0.001 par value per share, 500,000,000 of which have been classified as Class D shares and 500,000,000 of which have been classified as Class T shares (collectively, "Shares" and respectively, "Class D shares" and "Class T shares"). As of December 31, 2023, the Adviser owned 68% 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. | |||||
