Basis Of Presentation And Summary Of Significant Accounting Policies [Abstract]
Nature Of Operations	The accompanying financial statements, in the opinion of management, include all adjustments (consisting only of normal recurring adjustments) necessary for a fair presentation of Nestor Partners’ (the “Partnership”) financial condition at March 31, 2025 (unaudited) and December 31, 2024 (audited) and the results of its operations for the three months ended March 31, 2025 and 2024 (unaudited). These financial statements present the results of interim periods and do not include all disclosures normally provided in annual financial statements. It is suggested that these financial statements be read in conjunction with the audited financial statements and notes included in the Partnership's annual report on Form 10-K filed with the Securities and Exchange Commission for the year ended December 31, 2024. The December 31, 2024 information has been derived from the audited financial statements as of December 31, 2024.
Basis Of Presentation	The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”), as detailed in the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“Codification”), requires management to make estimates and assumptions that affect the amounts and disclosures reported in the financial statements. Actual results could differ from these estimates.
Income Taxes	Income Taxes (Topic 740) of the Codification clarifies the accounting for uncertainty in tax positions. This requires that the Partnership recognize in its financial statements the impact of any uncertain tax positions. Based on a review of the Partnership’s open tax years, 2021 to 2024, Millburn Ridgefield LLC (the “General Partner”) has determined that no reserves for uncertain tax positions were required.
Investments	Investment Company Status: The Partnership is for U.S. GAAP purposes an investment company in accordance with FASB Codification 946 Financial Services – Investment Companies.
