Type: String

Optional market assigned sub identifier for a trading phase within a trading session. Usage is determined by market or counterparties. Used by US based futures markets to identify exchange specific execution time bracket codes as required by US market regulations.

Bilaterally agreed values of data type "String" that start with a character can be used for backward compatibility

Valid values:

  • 1 = Pre-Trading
  • 2 = Opening or opening auction
  • 3 = (Continuous) Trading
  • 4 = Closing or closing auction
  • 5 = Post-Trading
  • 6 = Scheduled intraday auction
  • 7 = Quiescent
  • 8 = Any auction
  • 9 = Unscheduled intraday auction

    An unscheduled intraday auction might be triggered by a circuit breaker.

  • 10 = Out of main session trading

    In the context of Market Model Typology "Out of main session trading" refers to both before and after session, neither auction nor continuous trading.

  • 11 = Private auction

    An auction phase where only two parties participate.

  • 12 = Public auction

    An auction phase where all trading parties participate.

  • 13 = Group auction

    An auction phase limited to specific parties (e.g. parties that have resting orders in the order book).

  • 14 = Order initiated auction

    Auction automatically triggered by an order, e.g. an incoming order or a resting order that can be matched based on an incoming order. Use 9="Unscheduled intraday auction" for any other auctions that are not scheduled. In the context of Market Model Topology, this can be used for an on demand auction (a.k.a. frequent batched auction).
