How TMAC works for Equity Index futures

The TMAC mechanism allows clients to mitigate execution risk during the settlement period in the trading session. Clients can execute at the marker price even outside of U.S. hours. TMAC trades off a "base price" of zero (equal to the daily futures fixing  price) to create a differential versus the daily settlement price in the underlying futures contract month. The TMAC clearing price equals the daily fixing price of the underlying futures contract month plus or minus the TMAC transaction price.
