How TAS works for Cryptocurrency futures

The TAS mechanism allows clients to mitigate execution risk during the settlement period in the trading session. Clients can execute at the settlement price even outside of U.S. hours. 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.
