The Trading Session List Request (BI) is used to request a list of trading sessions available in a market place and the state of those trading sessions. The request can be modified to request status on a particular trading session (by specifying the TradingSessionID (336) (tag 336) and TradingSessionSubID (625) (tag 625) (if used by the market place). The request can be used to request a list of trading sessions that use a particular trading method or mode (such as electronic) by specifying the TradSesMethod (338) (tag 338) and/or TradSesMode (339) .
A successful request will result in a response from the counterparty of a Trading Session List (BJ) (MsgType=BJ) message that contains a list of zero or more trading sessions.
It is recommended that the TradSesReqID (335) be used to provide a unique identifier for the request. This value should be returned by the counterparty in the Trading Session List (BJ) messages sent in response to the request.
The Trading Session List Request (BI) follows the standard request model in providing the SubscriptionRequestType (263) (tag 263) field which can be used to obtain a snapshot of trading session information, subscribe for a snapshot with subsequent updates, or to unsubscribe from a previous subscription request.
