想把MACD的顏色放在主圖的K棒上 該如何修改程式?

各位大大/高手大家好:

小弟剛開始學寫XS語法的程式，想把MACD的顏色放在主圖的K棒上 該如何修改下列程式?

有請各位大大/高手指正，感謝萬分!

input: FastLength(12), SlowLength(26), MACDLength(9);

variable: difValue(0), macdValue(0), oscValue(0),var0( 0 ), var1( 0 ), var2( 0 ) ;

SetTotalBar((maxlist(FastLength,SlowLength,6) + MACDLength) * 4);

SetInputName(1, "DIF短期期數");

SetInputName(2, "DIF長期期數");

SetInputName(3, "MACD期數");

MACD(weightedclose, FastLength, SlowLength, MACDLength, difValue, macdValue, oscValue);

var0 = MACD(weightedclose, FastLength, SlowLength, MACDLength, difValue, macdValue, oscValue)

var1 = XAverage( var0, MACDLength(9) ) ;

var2 = var0 - var1 ;

if var2>0 then PlotPaintBar(High,Low,Open,Close,"",red) 

else PlotPaintBar(High,Low,Open,Close,"",green) ;
