Ibarshift return -1

[Megha Relan]

Hello all

I have an issue to get ibarshift value.

Actually my current chart is m1 and i get open value from h1.

If i am working on future candle then i know i barshift is 0.but when i work on history bar

Let say m1 chart current time 27 oct 2021-11:55

And i try to the value of 60bar it mean then time is 27 oct 2021-10:55.. so i want to return 1 According to h1

Please help me to solve this

Thank you in advance

to get bar number from datetime :

   datetime newDt= TimeCurrent()-PeriodSeconds(PERIOD_H1);
   int n= iBarShift(_Symbol,PERIOD_M1, newDt, true);
   Print(TimeToString(newDt), " - bar: ", IntegerToString(n));

but when you use "true" & this date is absent on this chart (e.g. week_end or the hole on the chart) - of course you will get -1 -- see iBarShift...

if you'd like to get vc.vs.datetime from bar_number - you do not need iBarshift

   Print(iTime(_Symbol,PERIOD_H1,1)); 
   Print(iTime(_Symbol,PERIOD_M1,60));
