Need help Calculating total Bars between 2 Time points!

[denialyg]

Hi all,

Ive been stuck trying to figure out how to solve this. Could some kind soul help me out or point in me the right direction please.
Basically Ive got 2 time points, a starting and ending time. I want to get the total number of bars shown on chart between these 2 points. Ive tried using (EndTimeRange -StartTimeRange * 60 * Period() ) but this included weekends into the total number.

Is the below code correct or is that a much simplier way to handle this?

Code: Select all

 
string STR ="2015.08.06 15:30" ; //Starting time example
string ETR ="2015.08.07 15:30" ; //Ending time example
 
 datetime StartTimeRange = StrToTime(STR) ; 
 datetime EndTimeRange = StrToTime(ETR);
  
int XDBars1=iBarShift(Symbol(),0,StartTimeRange,true);
int XDBars2=iBarShift(Symbol(),0,EndTimeRange,true);
int XDBars= XDBars1-XDBars2;

Also how do I countback bars based on a time point? eg. Based on EndTimeRange, i want to count backwards 1000 bars and get the data from that bar?

Much appreciated!

Code: Select all

      datetime STR = D'2015.08.06 15:30'; 
      datetime ETR = D'2015.08.07 15:30'; 
        
      int XDBars1=iBarShift(Symbol(),0,STR,true);
      int XDBars2=iBarShift(Symbol(),0,ETR,true);
      int XDBars= XDBars1-XDBars2;
         
      Alert(XDBars);//Remove this when you are confident the code is correct
      
      //Find the shift 1000 bars ago
      int shift = XDBars2 + 1000;
      Alert(shift);//Remove this when you are confident the code is correct

Well done for trying to sort this stuff out for yourself. You fell foul of a particularly difficult problem. Empty4 lack-of-useful-help is as useful as a chocolate fire guard. I learned the solution by studying the code of other coders, so don't feel useless.

Thanks Steve,
Glad to know I was on the right track.
I've been learning through referencing other coders codes and lots of trial and error, was the easiest way to pick up and learn mql4 for a person with 0 background in programming.

Thanks again!
