Try this:

Return Close, HistoGreen as “HistoGreen” Coloured(“Green”) Style(Histogram), HistoRed as “HistoRed” Coloured(“Red”) Style(Histogram)

I tried, it seems your line is correct, but still the histogram does not appear, could you please check the whole code

It seems that “HistoRed” is always equal to zero…

Also check the settings of the indicator (style=Histogram)… (see screenshot)
