Correct way to calculate an indicator in a for loop

[[Deleted]]

Hi everyone,

I wish to know if this is the correct way to calculate indicator's value in a for loop (throughout all the available bars):

int OnCalculate(...)

{

//... 

ArraySetAsSeries(SignalLine,false); 

//... 

for(int i=0; i<Bars; i++)

{ 

   double ma=iMA(NULL,0,MaPeriod,0,MaMethod,MaPrice,i);

//...

SignalLine[i]=ma;

}

//...

} 

return rates_total

} 

P.S. Logically in this simple case I would like to represent and plot a MA replication by iMA object. But I am not sure of how I set the loop. I get a bit of difference compared to the one calculated with built-in MT4. I cannot figure out why!

Thanks

ArraySetAsSeries(SignalLine,false); 

By setting the buffer not to be as series, the iMA calculation for the last bar on the chart will be applied to the first bar on the chart, so back to front.

Ok thanks!
