When a Clearing Member buys and sells or (vis-à-vis the Clearing House) is deemed to buy and sell Contracts for the same series and such Contracts are cleared through the Clearing House, the purchases and sales are not automatically offset one against the other where the relevant account is a gross position account. Transactions can only be offset against one another by complying the rules of the Relevant Market(s) at which they were effected and by submission of a close out request to the Clearing House by the relevant Clearing Member.
