A Trading Member may take the following actions if a selling customer fails to deliver securities that have been sold in the ready market or through a Futures Contract:—
(1) Recover from the customer the difference between the contract price and the market price at the time delivery should have been made, and all losses and consequent expenses; or
(2) Repurchase the securities and recover from the customer the difference between the contract price and the repurchase price upon the repurchase. Repurchase may be made immediately after the failure or at any other time. A Trading Member need not give notice of the repurchase to the selling customer.
