Statements to do plots following calculations are pretty straight
forward ... If you are looking to plot the histogram of the
difference between the MACD and the Signal Line you could do so
with ...
/* MACD */
MACDL1 = 12;
MACDL2 = 26;
MACDLT = 9;
Array = C;
MACD1 = EMA(Array, MACDL1);
MACD2 = EMA(Array, MACDL2);
MACDD = MACD1 - MACD2;
MACDT = EMA(MACDD, MACDLT);
MACDX = MACDD - MACDT;
Color = IIf(MACDX > 0, colorBrightGreen, colorRed);
Title = "MACD = " + WriteVal(MACDx);
Plot(MACDX, "MACD", Color, styleHistogram | styleThick);
