Bars Reference

[Carlos_R]

Hello,

My name is Carlos, I am new here.

I started to develop an indicator and I expected that using this type of code:

double iHigh(string symbol,ENUM_TIMEFRAMES timeframe,int index)

{
   if(index < 0) return(-1);
   double Arr[1];
   if(CopyHigh(symbol,timeframe, index, 1, Arr)>0)
        return(Arr[0]);
   else return(-1);
}

It would be possible to get the value of the last bar using this

iHigh(NULL,0,2)

But it appears this message:

'iHigh' - function can be declared only in the global scope

Could someone help me to find a way to use information of past bars to create an indicator ?

Thank you

When in doubt, think. You declared your function inside another function. Move it outside of the enclosing function. Or check your brackets.
