MarketPosition出了问题

老师您好，我的开仓出现了重复开多单，或重复开空单的现象，我把信号和MarketPosition打印出来，发现跟策略交易里的多仓和空仓对不上，多仓为1时，MarketPosition打印出来却是-1，还有一个问题，我把开仓保存到记录文件里，只有一个记录，有时候却产生两个委托，有时候会提示信号闪烁。这是什么原因呢？ if (BarStatus == 2) Print(Text(SystemDateTime) + "," + Text(Date + Time) + "," + Symbol + ",Position=" + Text(MarketPosition) + ",BBIsStop=" + Text(BBIsStop) + ",BBDirection=" + Text(BBDirection)); If (MarketPosition <> 1) { if (BBIsStop == 1 && BBDirection == 1) { if (BarStatus == 2) FileAppend("D:\\TB交易记录\\" + Symbol() + ".tbf", Text(SystemDateTime) + "," + Text(Date + Time) + "," + Symbol + ",平空开多," + Text(MarketPosition) + "," + Text(BBIsStop) + "," + Text(BBDirection)); Buy(AutoLots, Close); } } If (MarketPosition <> -1) { if (BBIsStop == 1 && BBDirection == -1) { if (BarStatus == 2) FileAppend("D:\\TB交易记录\\" + Symbol() + ".tbf", Text(SystemDateTime) + "," + Text(Date + Time) + "," + Symbol + ",平多开空," + Text(MarketPosition) + "," + Text(BBIsStop) + "," + Text(BBDirection)); SellShort(AutoLots, Close); } }
