The Trading Session List message is sent as a response to a Trading Session List Request. The Trading Session List should contain the characteristics of the trading session and the current state of the trading session.
The message could be relayed every trading day, or at least when trading sessions are changed. The user of the message has the ability to relay either Trading Sessions only or, if applicable, Trading SubSessions. Depending on characteristics of the market, the various Time fields may apply.
The Trading Session List should return the TradSesReqID <335>(tag 335) value from the Trading Session List Request originally sent by a counterparty.
