TAM or TAS Rules
Trading at Settlement (TAS) is subject to the requirements of Rule 524.A. TAS trades off a "Base Price" of zero (equal to the daily settlement price) to create a differential versus the daily settlement price in the underlying futures contract month. The TAS clearing price equals the daily settlement price of the underlying futures contract month plus or minus the TAS transaction price. TAS available in the nearest three months.
