CMTA and Post-trade Give Ups
OneChicago supports CMTA (Clearing Member Trade Assignment) and post-trade Give Ups/Allocations for all OneChicago products.
A CMTA agreement allows a transaction to be automatically moved from the executing firm into an account of a carrying firm, so long as the executing and carrying firms have an effective CMTA agreement registered with OCC for OneChicago. The destination firm must be supplied at the time of order entry or billateral trade submission (pre-trade).
A “Give Up” or “Allocation” allows a transaction by the executing firm to be turned over to the client’s carrying firm. Give Ups/Allocations are often used to consolidate many small orders or to dispense large ones. Allocations are designated post-trade at OCC.
All open shorts at the close of business on expiration day deliver stock and all long open interest pay for the delivered stock. The delivery process occurs through the National Securities Clearing Corporation (NSCC), the central counterparty clearing house for all US equities and the related Depository Trust Company (DTC) where the actual settlement occurs. The Options Clearing Corporation (OCC) and the NSCC guarantee delivery and payment of all OneChicago physically settled futures.
