separate_window indicator limited to 8 lines/histos?

New comment
 
I think I have read somewhere that it should be possible to add unlimited lines to an indicator (from memory Slawa said, that it's only limited by computer memory).

Below is a code that would use 10 but only 8 show in the indicator window (there should be two more red lines on level -100 and -200 in the window for HistoLevelM1 and M2).

(I know that I could use regular levels, but I want them colored, hence the implementation as indicator buffers).

see IndicatorBuffers function description and it's link "indicator_buffers".
see also "Features of Custom Indicators Creation"
 
Ahh okay! I think I misunderstood another post here on the forum then.
