TradingSessionID

Identifier for a trading session. A trading session spans an extended period of time that can also be expressed informally in terms of the trading day. Usage is determined by market or counterparties. To specify good for session where session spans more than one calendar day, use TimeInForce = 0 (Day) in conjunction with TradingSessionID(336). Bilaterally agreed values of data type 'String' that start with a character can be used for backward compatibility.

交易会话的标识符。交易会话跨越一段较长的时段，亦可用交易日这一非正式术语来表述。其使用方式由市场或交易对手方决定。若会话跨越多个日历日，则应使用TimeInForce = 0（当日）与TradingSessionID（336）相结合以指定当日有效。为保持向后兼容性，可使用以字符开头的字符串类型数据，并经双方协商确定其值。
