Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation and Use of Estimates The accompanying financial statements are prepared on the accrual basis of accounting in accordance with accounting principles generally accepted in the United States (“GAAP”). The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. The significant estimates affecting the accompanying financial statements are the fair values of RMBS and Eurodollar futures contracts.
Statement of Comprehensive Income	Statement of Comprehensive Income (Loss) In accordance with the Financial Accounting Standards Board’s Accounting Standards Codification (“FASB ASC”) Topic 220, Comprehensive Income, a statement of comprehensive income has not been included as the Company has no items of other comprehensive income. Comprehensive income (loss) is the same as net income (loss) for the periods presented.
Cash and Cash Equivalents and Restricted Cash	Cash and Cash Equivalents and Restricted Cash Cash and cash equivalents include cash on deposit with financial institutions and highly liquid investments with original maturities of three months or less. Restricted cash, of approximately $2,446,000 at December 31, 2013, represents cash held by a broker as margin on Eurodollar futures contracts. Restricted cash, totaling approximately $449,000 at December 31, 2012, represents cash held on deposit as collateral with repurchase agreement counterparties. The Company maintains cash balances at three banks, and, at times, balances may exceed federally insured limits. The Company has not experienced any losses related to these balances. All non-interest bearing cash balances were fully insured at December 31, 2012 due to a temporary federal program in effect from December 31, 2010 through December 31, 2012. Under the program, there was no limit to the amount of insurance for eligible accounts. Beginning January 1, 2013, insurance reverted to $250,000 per depositor at each financial institution. At December 31, 2013, the Company’s cash deposits exceeded federally insured limits by approximately $7.4 million. Restricted cash balances are uninsured, but are held in separate customer accounts that are segregated from the general funds of the counterparty. The Company believes that it is not exposed to any significant credit risk on cash and cash equivalents or restricted cash balances.
Mortgage-Backed Securities	Mortgage-Backed Securities The Company invests primarily in mortgage pass-through (“PT”) certificates, collateralized mortgage obligations, and interest only (“IO”) securities and inverse interest only (“IIO”) securities representing interest in or obligations backed by pools of mortgage-backed loans (collectively, “RMBS”). These investments meet the requirements to be classified as available for sale under ASC 320-10-25, Debt and Equity Securities (which requires the securities to be carried at fair value on the balance sheet with changes in fair value charged to other comprehensive income, a component of stockholders’ equity). However, the Company has elected to account for its investment in RMBS under the fair value option. Electing the fair value option allows the Company to record changes in fair value in the statement of operations, which, in management’s view, more appropriately reflects the results of our operations for a particular reporting period and is consistent with the underlying economics and how the portfolio is managed. The Company records RMBS transactions on the trade date. Security purchases that have not settled as of the balance sheet date are included in the RMBS balance with an offsetting liability recorded, whereas securities sold that have not settled as of the balance sheet date are removed from the RMBS balance with an offsetting receivable recorded. The fair value of the Company’s investments in RMBS is governed by FASB ASC 820, Fair Value Measurement. The definition of fair value in FASB ASC 820 focuses on the price that would be received to sell the asset or paid to transfer the liability in an orderly transaction between market participants at the measurement date. The fair value measurement assumes that the transaction to sell the asset or transfer the liability either occurs in the principal market for the asset or liability, or in the absence of a principal market, occurs in the most advantageous market for the asset or liability. Estimated fair values for RMBS are based on the average of third-party broker quotes received and/or independent pricing sources when available. Income on PT RMBS securities is based on the stated interest rate of the security. Premiums or discounts present at the date of purchase are not amortized. For IO securities, the income is accrued based on the carrying value and the effective yield. The difference between income accrued and the interest received on the security is characterized as a return of investment and serves to reduce the asset’s carrying value. At each reporting date, the effective yield is adjusted prospectively from the reporting period based on the new estimate of prepayments and the contractual terms of the security. For IIO securities, effective yield and income recognition calculations also take into account the index value applicable to the security. Changes in fair value of RMBS during each reporting period are recorded in earnings and reported as unrealized gains or losses on mortgage-backed securities in the accompanying statements of operations.
Derivative Financial Instruments	Derivative Financial Instruments The Company has entered into Eurodollar futures contracts to manage interest rate risk, facilitate asset/liability strategies and manage other exposures, and it may continue to do so in the future. The Company has elected to not treat any of its derivative financial instruments as hedges. FASB ASC Topic 815, Derivatives and Hedging, requires that all derivative instruments be carried at fair value. Changes in fair value are recorded in earnings for each period.
Financial Instruments	Financial Instruments FASB ASC 825, Financial Instruments, requires disclosure of the fair value of financial instruments for which it is practicable to estimate that value, either in the body of the financial statements or in the accompanying notes. RMBS and Eurodollar futures contracts are accounted for at fair value in the balance sheet. The methods and assumptions used to estimate fair value for these instruments are presented in Note 10 of the financial statements. The estimated fair value of cash and cash equivalents, restricted cash, accrued interest receivable, prepaid expenses and other assets, due from/to Bimini Capital Management, Inc., repurchase agreements, accrued interest payable, accounts payable, accrued expenses and others generally approximates their carrying values as of December 31, 2013 and 2012 due to the short-term nature of these financial instruments.
Repurchase Agreements	Repurchase Agreements The Company finances the acquisition of the majority of its PT RMBS through the use of repurchase agreements under master repurchase agreements. Pursuant to ASC Topic 860, Transfers and Servicing, the Company accounts for repurchase transactions as collateralized financing transactions, which are carried at their contractual amounts, including accrued interest, as specified in the respective agreements.
Management Fees [Policy Text Block]	Manager Compensation The Company is externally managed by Bimini Advisors, LLC, a Maryland limited liability company and wholly-owned subsidiary of Bimini (“the Manager” or “Bimini Advisors”). The Company’s management agreement with the Manager provides for the payment to the Manager of a management fee and reimbursement of certain operating expenses, which are accrued and expensed during the period for which they are earned or incurred. Refer to Note 11 for the terms of the management agreement.
Earnings Per Share	Earnings Per Share The Company follows the provisions of FASB ASC 260, Earnings Per Share. Basic earnings per share (“EPS”) is calculated as net income or loss attributable to common stockholders divided by the weighted average number of shares of common stock outstanding or subscribed during the period. Diluted EPS is calculated using the “if converted” method for common stock equivalents, if any. However, the common stock equivalents are not included in computing diluted EPS if the result is anti-dilutive.
Income Taxes	Income Taxes Bimini has elected to be taxed as a real estate investment trust (“REIT”) under the Internal Revenue Code of 1986, as amended (the “Code”). Until the closing of its IPO on February 20, 2013, Orchid was a “qualified REIT subsidiary” of Bimini under the Code. Beginning with its short tax period commencing on February 20, 2013 and ended December 31, 2013, Orchid will elect and intends to qualify to be taxed as a REIT. REITs are generally not subject to federal income tax on their REIT taxable income provided that they distribute to their stockholders at least 90% of their REIT taxable income on an annual basis. In addition, a REIT must meet other provisions of the Code to retain its tax status. Orchid measures, recognizes and presents its uncertain tax positions in accordance with FASB ASC 740, Income Taxes. Under that guidance, Orchid assesses the likelihood, based on their technical merit, that tax positions will be sustained upon examination based on the facts, circumstances and information available at the end of each period. All of Orchid’s tax positions are categorized as highly certain. There is no accrual for any tax, interest or penalties related to Orchid’s tax position assessment. The measurement of uncertain tax positions is adjusted when new information is available, or when an event occurs that requires a change.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In July 2013, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) 2013-11, Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists. This new standard requires the netting of unrecognized tax benefits against a deferred tax asset for a loss or other carryforward that would apply in settlement of the uncertain tax positions. Under the new standard, unrecognized tax benefits will be netted against all available same-jurisdiction loss or other tax carryforwards that would be utilized, rather than only against carryforwards that are created by the unrecognized tax benefits. The ASU is effective beginning January 1, 2014 on either a prospective or retrospective basis. The guidance represents a change in financial statement presentation only and the Company does not expect that this ASU will have a material impact on its financial results. In June 2013, the FASB issued ASU 2013-08, Financial Services – Investment Companies (Topic 946): Amendments to the Scope, Measurement, and Disclosure Requirements. The amendments in this Update modify the guidance for determining whether an entity is an investment company, update the measurement requirements for noncontrolling interests in other investment companies and require additional disclosures for investment companies under US GAAP. The amendments in the Update develop a two-tiered approach for the assessment of whether an entity is an investment company which requires an entity to possess certain fundamental characteristics while allowing judgment in assessing other typical characteristics. The amendments in this Update also revise the measurement guidance in Topic 946 such that investment companies must measure noncontrolling ownership interests in other investment companies at fair value, rather than applying the equity method of accounting to such interests. The new guidance is effective for an entity’s interim and annual reporting periods in fiscal years that begin after December 15, 2013. Earlier application is prohibited. The Company does not expect that this ASU will have a material impact on its financial statements. In February 2013, the FASB issued ASU 2013-04, Liabilities (Topic 405): Obligations Resulting from Joint and Several Liability Arrangements for Which the Total Amount of the Obligation Is Fixed at the Reporting Date ("ASU 2013-04"). The objective of the amendments in this update is to provide guidance for the recognition, measurement, and disclosure of obligations resulting from joint and several liability arrangements for which the total amount of the obligation within the scope of this guidance is fixed at the reporting date, except for obligations addressed within existing GAAP. The amendments in ASU 2013-04 are effective for fiscal years, and interim periods within those years, beginning after December 15, 2013, and should be retrospectively applied to all prior periods presented for those obligations resulting from joint and several liability arrangements within the ASU's scope that exist at the beginning of an entity's fiscal year of adoption. Early adoption is permitted. The Company does not expect that this ASU will have a material impact on its financial statements.
