using build 670 and having brain fart - need help with iCustom in EA

Hi,

I'm stuck and would appreciate some assistance...

I'm trying to use iCustom in a EA.  I have to supply a shift as the last parameter of iCustom but I don't want to look at bars I've already processed.  I tried using the following:

void OnTick()
  {
   
   int counted_bars=IndicatorCounted();

Print("counted_bars=",counted_bars);
   if(counted_bars<0)
      return;
   if(counted_bars>0)
      counted_bars--;

... and then calling iCustom in a loop.  I assume because it is an EA, IndicatorCounted() returns -1 so the loop never enters.

How do I include iCustom in an EA and make sure I can send the proper shift value to iCustom?

Thanks,

Neil
