Trade At Marker Or Trade At Settlement 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. Trading at Marker (TAM) is analogous to Trading at Settlement (TAS) wherein parties are permitted to trade at a differential to a not-yet-known price. TAM uses a marker price, whereas TAS uses the Exchange-determined daily settlement price for the underlying futures contract month.
