MACDDiff5min = data0.XAverage( data0.Close, FastLength ) - data0.XAverage( data0.Close, SlowLength ) ;//计算MACDDiff5min

AvgMACD5min = data0.XAverage(MACDDiff5min,MACDLength);

MACDValue = MACDDiff5min - AvgMACD5min;

PlotNumeric(\"MACDDiff5min\",MACDDiff5min);                                                                                                //显示MACDDiff5min

MACDDiff1min = data1.XAverage( data1.Close, FastLength ) - data1.XAverage( data1.Close, SlowLength ) ; //计算MACDDiff1min

       data1.PlotNumeric(\"MACDDiff1min\",MACDDiff1min) ;                                                                                          //显示MACDDiff1min

请问为什么MACDdiff5min在图表显示正常，而MACDDiff1min却一直显示为0？
