selecting input variables in intervals of 'x' minutes.

Is there a way i can take the values of open and close of every minute from 0000 to 0015 and then for next 15 minutes and so on. without writing a loop with a difference of 15 mins. Is there any such function in mql4. pardon me for my ignorance.

MQL4 has no built in fumction that does that you would have to code it.

Your question makes no sense. Take the values where, why. Why don't you want a loop. What is a difference of 15 minutes from/to what?

@SDC:fine got it thanks.

@whroeder: i wanted the values of open and close prices in intervals of 15 mins. the values of open and close from 0000 to 0015 hours. similarly the the values of open and close from 0015 to 0030. sets of open close data.

You can record them in real time to a file if you dont want to use a loop.
