Dear guys,

Use this - it can show open line for any available time frame

Hi!! Thanks a lot MLaden!!! :)

But could you kindly see if you can make it into something like this? (similar to "daily open line", H1 and H4 lines were drawn manually to show example)

So it's not a continuous line like a moving average. But a horizontal line that stop extending at the bar of chosen timeframe.

Thanks in advance, sir!!

Regards

In that case you have to have a bit more complicated code

Like this :

                const long     &volume[],
                const int &spread[])
{
   int counted_bars = prev_calculated;
      if(counted_bars < 0) return(-1);
      if(counted_bars > 0) counted_bars--;
           int limit=MathMin(rates_total-counted_bars,rates_total-1);

           for(int i=limit; i>=0; i--)
               if (i<Bars-1)
                  if (iBarShift(NULL,TimeFrame,time[i]+TimeZoneOFData*3600)==iBarShift(NULL,TimeFrame,time[i+1]+TimeZoneOFData*3600))
                         line[i] =  line[i+1];
                  else { line[i] =  open[i]; if (TimeFrame!=_Period) line[i+1] = EMPTY_VALUE; }
               else      line[i] =  open[i];
   return(rates_total);
}

Replace the previous version with this one and you shall have discontinued lines - without a need to create objects - object could be more precise (you would not have that one empty bar) but would also create a whole lot of objects that is never a good idea with terminal, so this way would be something of a most efficient way for that task
