Here modifie for this :

if(counted_bars==0) limit = MathMin(Bars-10-1,Bars-MathMax(FastEMA,SlowEMA)-1);
   else                limit = Bars-counted_bars;
//------------------------------------------------------------------------------

if(counted_bars==0) limit = Bars-(FastEMA+SlowEMA+1);
   else                limit = Bars-counted_bars;

The OnCalculate is useless; it can be replaced by   int start()  

it works but it doesnt indicate/print the arrow base on my initial settings like the one am having problem with.

sir , dont forget me on this matter .

what am trying to said is that the indicator doesn't work in the same way. please look at the below image sir.
