Date Conversions

Eaglehawk · #1 (**permalink**) 07-16-2007, 06:00 AM

i've been away from metrader 4 for a while, so my coding is a little rusty, while creating an indicator, reason has arisen to convert a distance between two datetime variable into a number of bars, i think i may have it, but i'm not so sure about subtraction of datetimes, will these expressions do the trick?

PHP Code:


			
  datetime center_time = ObjectGet(line,OBJPROP_TIME1);//horizontal refrence to center, or left point of line
  double center_height = ObjectGet(line,OBJPROP_PRICE1);//vertical refrence to center, or left point of line
  datetime radius_time = ObjectGet(line,OBJPROP_TIME2);//horizontal refrence to outer, or right point of line
  double radius_height = ObjectGet(line,OBJPROP_PRICE2);//vertical refrence to outer, or right point of line
  double Distance_g = (radius_time - center_time)/Period();

line is a variable that represents a line already drawn.

thanks in advance for any and all help.

Try this:

PHP Code:


			
 int NumBars = MathRound((EndTime - StartTime)) / (Period*60));

Or maybe more precise in some cases:

PHP Code:


			
 int StartShift = iBarShift(NULL,0,StartTime,false);

 int EndShift = iBarShift(NULL,0,EndTime,false);

 int NumBars = StartShift - EndShift;

this looks precise, and it makes sense,

thanks again for the help!
