Each trade on Blue Ocean ATS includes a Trade Match ID (TrdMatchID) assigned through MEMO SBE v1.13.
This ID appears in the ExecutionReport_Trade message and identifies the exact trade within the session.
Each TrdMatchID is unique across all symbols for that session. It is created by the system, not calculated, and cannot be predicted or reused.
Blue Ocean ATS operates from 8:00 PM ET to 4:00 AM ET. No TrdMatchID repeats within that window.
For example, a trade executed at 10:45 PM ET on November 11 receives a TrdMatchID specific to that session. It will not appear in any other trade or symbol that night.
Each ID provides a clear audit trail for every overnight execution.
