请教老师，macd系统指标被改坏了该怎么恢复呀

图中指标看不出改了啥，就报错了，悲剧。。。。所有代码都报这个错，行情报价的字段也报错，k线图副图指标也报错Params Numeric FastLength(12); Numeric SlowLength(26); Numeric MACDLength(9);Vars Numeric MACDDiff; Numeric AvgMACD; Numeric MACDValue;Events OnReady() { Range[0:DataSourceSize() - 1] { setPlotOption("MACDDiff", "begin-bar", SlowLength); setPlotOption("MACDDEA", "begin-bar", SlowLength + MACDLength); setPlotOption("MACD", "begin-bar", SlowLength + MACDLength); } } 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,Color9(),Enum_Bar); Else PlotAuto("MACD",MACDValue,0,Color10(),Enum_Bar); PlotNumeric("零线",0); } }
