麻烦大佬帮帮忙/(ㄒoㄒ)/~~

2个问题:1、交易时间结束前持仓全部平仓;2、交易时间开始样本数重新记录这应该怎么编写下面策略是可以编译的Params Numeric FastLength(12); Numeric SlowLength(26); Numeric MACDLength(9);Vars series<Numeric> MACDDiff; Numeric AvgMACD; Numeric MACDValue; Numeric AvgValue1; Numeric AvgValue2;EVENTS OnBarOpen(ArrayRef<Integer> indexs) { Range[0:DataSourceSize() - 1] { MACDDiff = XAverage(Close, FastLength) - XAverage(Close, SlowLength); AvgMACD = XAverage(MACDDiff, MACDLength); MACDValue = MACDDiff - AvgMACD; AvgValue1 = XAverage(Close, 10); // 根据实际情况修改平均值1 AvgValue2 = XAverage(Close, 20); // 根据实际情况修改平均值2 if (MACDDiff > 0 && MACDDiff > MACDDiff[1] && MarketPosition <> 1) { Buy(2, Open); } if (MACDDiff < 0 && MACDDiff < MACDDiff[1] && MarketPosition <> -1) { SellShort(2, Open); } if (MACDDiff < 0 && MACDDiff > MACDDiff[1] && MarketPosition <> 1) { Sell(2, Open); } if (MACDDiff > 0 && MACDDiff < MACDDiff[1] && MarketPosition <> -1) { BuyToCover(2, Open); } } }
