Directly getting past candle data

Hey guys,
I was wondering if there is a way to get a specific candles time. Right now I am using math to get this data from my charts. I am hoping there is a more elegant way to perform this. I am worried that there may be some chart error and say a candle is missing, this would now point me at the 4:59 candle, and could throw off my results.


Here is my example that I am using now. Say it is 10:01, and I want to get the close of the current charts m1 candle at 5:00 am, I would use the following:

iClose(NULL,PERIOD_M1,+(TimeHour(TimeCurrent())*60)+(TimeMinute(TimeCurrent())) -301);


I tried looking through codebase, but did not see a function that I could call.
Thanks,
Dale

you should explore iBarShift.

e.g.

Inserted Code
datetime some_time = D'2008.12.22 05:00';
int shift = iBarShift (NULL, PERIOD_M1, some_time, false);
double fiveAMClose = iClose (NULL, PERIOD_M1, shift);

Zen,
Thanks for the information. It took me a little while to figure it out, but mostly because I do not know how to program, here is what I ended up doing,

Inserted Code
   string thisyear=Year();
   string thismonth=Month();
   string thisday=Day();
   string timeframe= StringConcatenate(thisyear,".",thismonth,".",thisday," 05:00");
   datetime todayinfo = StrToTime(timeframe);
   Print (timeframe);
   double ujdo=iOpen(NULL,PERIOD_M1,iBarShift(NULL,PERIOD_M1,todayinfo,false));

Of course to get the close, I just substituted the iOpen for the iClose.

This method works much better than my old method as it actually forcast the bar count based on the terminal and not a static number. I found that my mt4, even if kept running, had a tendency to drop some m1 bars, which threw off my indicator.
