t2 in ObjectCreate (OBJ_TREND,) dont cover holidays

[abd-]

hi

am using a code to draw a horizontal trend line from t1, p1  to t2,p1 (which will draw it horizontally and to the right) . 

some time i tried to draw the trend line for example  : over  90 bars but because of the holidays the trend line will not cover  90 bars.. 

how to solve this?

You may try this solution:

datetime CorrectTime(datetime time, int bars_forward)
{
   int counted=0;
   while(counted<bars_forward)
   {
      if(iBarShift(_Symbol, PERIOD_CURRENT, time, true)!=-1 || time>Time[0])
         counted++;
      time+=PeriodSeconds();
   }      
   return time;   
}

A Tline is from time one to time two. It is not over bars.

You assume that every bar every exists — they don't. What if there are no ticks during a specific candle period? There can be minutes between ticks during the Asian session, think M1 chart. Larger charts, think weekend, market holiday (country and broker specific), requires knowledge of when your broker stops and starts (not necessary the same as the market.)

Hi

I don’t think that there is a better solution that going in a loop through history and count those 90 bars and find the times of the starting and ending point of the loop.

There is no universal way to work on times using bars only – just make your code base on available data from chart.
