Thank you very much Nicolas,

unfortunately the command “coloured by” does not work properly for me. The indicator gets calculated but the different colours for positive or negative values are not working if there are more then one output variables (I am using v10.2).

However here is a solution that works for me. Not nice but who cares 😉

In this “dummy” example on the top level every second bar will be green every forth bar will be red and the rest will be black. On the bottom level every third bar will be green every sixth bar will be red and the rest will be black.

// Set each output variable to be shown as histogram
// Set the correct colour for each output variable (Lev1Black="black", Lev1Green="green"...)
iBar=IntradayBarIndex
Lev1Black=0
Lev1Green=0
Lev1Red=0
Level=5
if (ibar MOD 2 =0) and (ibar mod 4 <>0) then
Lev1Green=Level
elsif  ibar MOD 4 =0 then
Lev1Red=Level
else
Lev1Black=Level
endif

Lev2Black=0
Lev2Green=0
Lev2Red=0
Level=2.5
if (ibar MOD 3 =0) and (ibar mod 6 <>0) then
Lev2Green=Level
elsif  ibar MOD 6 =0 then
Lev2Red=Level
else
Lev2Black=Level
endif
return 0 as "Zero",Lev1Black  as "Level-1 (black)",Lev1Green as "Level-1 (green)",Lev1Red as "Level-1 (red)",Lev2Black  as "Level-2 (black)",Lev2Green as "Level-2 (green)",Lev2Red as "Level-2 (red)"
