求大佬帮忙改改/(ㄒoㄒ)/~~

Params Numeric FastLength(12); Numeric SlowLength(26); Numeric MACDLength(9); Vars Numeric MACDDiff; Numeric AvgMACD; Numeric MACDValue; Numeric AvgValue1; Numeric AvgValue2; Begin OnBar(ArrayRef<Integer> indexs) Begin Range[0:DataSourceSize() - 1] Begin 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) Begin Buy(0, Open); End; if (MACDDiff < 0 && MACDDiff < MACDDiff[1] && MarketPosition <> -1) Begin SellShort(0, Open); End; if (MACDDiff < 0 && MACDDiff > MACDDiff[1] && MarketPosition <> 1) Begin Sell(0, Open); End; if (MACDDiff > 0 && MACDDiff < MACDDiff[1] && MarketPosition <> -1) Begin BuyToCover(0, Open); End; End; End; End;翻译说是BEGIN-END不匹配不知道啥原因，求个大佬给修修/(ㄒoㄒ)/~~
