Indicator is on chart but is invisible

[Almernio Gutramolino]

if I right click in that spot, where i know the indicator should be, it shows me that it is there....but i can only see colors in the strategy tester, and only after the beginning of the strategy tester(not on previous data)

I thought there was some problem with the code, but the indicator is actually there...

You have like this:

   if(prev_calculated< 7)
     {
      limit= 2 ;
      ArrayInitialize(ExtMixedBuffer,EMPTY_VALUE);
      ArrayInitialize(ColorLineColors,EMPTY_VALUE);
     }
   else
      limit=rates_total- 6 ;

do this:

   if(prev_calculated< 7)
     {
      limit= 2 ;
      ArrayInitialize(ExtMixedBuffer,EMPTY_VALUE);
      ArrayInitialize(ColorLineColors,0.0);
     }
   else
      limit=rates_total- 6 ;
