exchange.GetTickers

exchange.GetTickers()函数用于获取已订阅交易品种的聚合行情数据（{@struct/Ticker Ticker}结构数组）。

exchange.GetTickers()函数请求数据成功时返回{@struct/Ticker Ticker}结构数组，请求数据失败时返回空值。 {@struct/Ticker Ticker}数组 / 空值

} 在回测系统中调用exchange.GetTickers()“`函数，仅返回已订阅合约的聚合行情数据。

注意事项：

• exchange.GetTickers()函数支持实盘和回测系统。

• exchange.GetTickers()函数仅返回已订阅品种的相关数据。
