Topics concerning MT4 and MQL4 have their own section.
In future please post in the correct section.
I will move your topic to the MQL4 and Metatrader 4 section.

//limit = Bars - counted_bars + TimeFrame / Period();
if (counted_bars == 0)
   limit = Bars - 5;
else
   limit = 5 + TimeFrame / Period() * 5;
