ATR equal zero

[[Deleted]]

Hi Guys,

ATR calculated for a shift bigger than about 8500 bars always results in zero. Do you have any ideas why and how to solve it?

wrote this code to check it:

int start()
{
 
 int i;
 while(i < 10000)
 {
  double ATR = iATR(Symbol(),60,10,i);

  if(ATR == 0)
   {
    Alert(Symbol()," ",i,": ATR: ",ATR);
    return(0);
   }
  i++;
 }
 return(0);
}

Thank you for any hint!

double ATR = iATR(Symbol(),60,10,i);

1. You have no PERIOD_H1 history that far back. Print iBars(Symbol(), PERIOD_H1) to verify.
   
2. Download history.
3. Write self documenting code, not hard coded numbers

   double ATR = iATR(Symbol(),PERIOD_H1,10,i);
   double ATR = iATR(NULL,PERIOD_H1,10,i); // current pair, H1.
   double ATR = iATR(NULL,0, 10,i);        // current pair, current TF.

Thanks!

You are right - iBars(Symbol(), PERIOD_H1) verifies it. Thought I have enough history as the chart shows candles.

Would you explain the advantage of the shown self documenting (even don´t know what that means?) code?

So you will understand the code tomorrow. What does zero mean?

In ArrayCopySeries(), iHighest() and iLowest() functions.	MODE_OPEN
In timeframes	current chart
In OrderSend()	OP_BUY
In iMA, etc.	current pair or current TF or PRICE_CLOSE or MODE_SMA depending on which argument
In Drawing styles	DRAW_LINE
In Colors	Black
In iMACD(), iRVI() and iStochastic()	MODE_MAIN
In ObjectCreate(), ObjectsDeleteAll() and ObjectType()	OBJ_VLINE
In UninitializeReason()	Script returned from start
From GetLastError()	ERR_NO_ERROR

That's no where near complete.

Do you really expect to remember what each value means. Will you remember 2 months from now?

that makes sense, thank you :)
