Subscriptions, Redemptions and Allocation of Net Income or Loss   Subscriptions received in advance, if any, represent cash received prior to June 30 for contributions of the subsequent month and do not participate in earnings of the Partnership until the following July.   Class A, Class B, Legacy 1 Class, Legacy 2 Class, Global 1 Class, Global 2 Class and Global 3 Class Limited Partners have the right to redeem units as of any month-end upon ten (10) days’ prior written notice to the Partnership. The General Partner, however, may permit earlier redemptions in its discretion. Legacy 1 Class, Legacy 2 Class, Global 1 Class, Global 2 Class and Global 3 Class Limited Partners are prohibited from redeeming such units for the three months following the subscription for units. Global 3 Class Limited Partners who redeem their units after the three-month lock-up, but prior to the one-year anniversary of their subscriptions for the redeemed units, will pay the applicable early redemption fee. There are no redemption fees applicable to Legacy 1 Class, Legacy 2 Class, Global 1 Class and Global 2 Class Limited Partners or to Global 3 Class Limited Partners who redeem their units on or after the one-year anniversary of their subscription. Redemptions will be made as of the last day of the month for an amount equal to the net asset value per unit, as defined, represented by the units to be redeemed. The right to obtain redemption is also contingent upon the Partnership’s having property sufficient to discharge its liabilities on the redemption date and may be delayed if the General Partner determines that earlier liquidation of commodity interest positions to meet redemption payments would be detrimental to the Partnership or nonredeeming Limited Partners.   In addition, the General Partner may at any time cause the redemption of all or a portion of any Limited Partner’s units upon fifteen (15) days’ written notice. The General Partner may also immediately redeem any Limited Partner’s units without notice if the General Partner believes that (i) the redemption is necessary to avoid having the assets of the Partnership deemed Plan Assets under the Employee Retirement Income Security Act of 1974, as amended (“ERISA”), (ii) the Limited Partner made a misrepresentation in connection with its subscription for the units, or (iii) the redemption is necessary to avoid a violation of law by the Partnership or any Partner.   In accordance with the Third Amended and Restated Limited Partnership Agreement, net income or loss of the Partnership is allocated to partners according to their respective interests in the Partnership as of the beginning of the month. </div>falsefalsefalsenonnum:textBlockItemTypenaThe entire disclosures of subscriptions, redemptions and allocation of net income loss.No definition available.false0Subscriptions, Redemptions and Allocation of Net Income or LossfalseSubscriptions, Redemptions and Allocation of Net Income or LossUnKnownUnKnownUnKnownUnKnowntruefalsefalseSheethttp://www.grantparkfunds.com/role/DisclosureSubscriptionsRedemptionsAndAllocationOfNetIncomeOrLoss12
