Подскажите пожалуйста в чем ошибка?

[Dmitry Fedoseev]

При IndicatorCounted()=0 надо лимит на 1 бар уменьшить.

Вот с таким началом будет работать: 

int start()
  {
   double atr,ll,hh,lma,hma;
   int workbar=1;
   
   int limit=Bars-IndicatorCounted()-1;
   if(IndicatorCounted()==0)limit--;
   
   for(int i=limit; i>=workbar; i --)

Спасибо огромное, заработало)))
