MACD在图标显示问题

Params Numeric FastLength(12); Numeric SlowLength(26); Numeric MACDLength(9); Vars Numeric MACDDiff; Numeric AvgMACD; Numeric MACDValue; Events OnBar(ArrayRef<Integer> indexs) { Range[0:DataSourceSize() - 1] { MACDDiff = XAverage( Close, FastLength ) - XAverage( Close, SlowLength ) ; AvgMACD = XAverage(MACDDiff,MACDLength); MACDValue = 2 * (MACDDiff - AvgMACD); PlotNumeric("MACDDiff",MACDDiff); PlotNumeric("MACDDEA",AvgMACD); If (MACDValue >= 0) PlotAuto("MACD",MACDValue,0,Red,Enum_Bar); Else PlotAuto("MACD",MACDValue,0,Green,Enum_Bar); PlotNumeric("零线",0); } }自己新建了一个公式，将系统自带的MACD复制过去，但重新加载自建的公式后，就变成这样，哪里出错了？
