Post subject:  Start Time of Historical Daily Bars
Hello,

I would like my strategy to retrieve the 6 previous daily bars.
I've found the IHistory.getBars method and have used it as follows.

long prevBarTime = history.getPreviousBarStart(Period.DAILY, askBar.getTime());
List<IBar> askBars = history.getBars(Instrument.EURUSD, Period.DAILY, OfferSide.ASK, Filter.WEEKENDS, 6, prevBarTime, 0);


The problem I've run into is the start time of the daily bars, they have a start time of midnight.
Which threw me because when you download historical data to CSV files or view daily bars in JForex they start at 21:00 (or 22:00 for parts of the year).

What I'm trying to get to is 1 bar for Sunday through Monday and 1 bar Monday through Tuesday etc... rather than 24 hour periods.
Is this possible?


Regards

Greetings.

Try this:

Period dailyEET = Period.createCustomPeriod(Unit.Day, 1, JFTimeZone.EET);
long prevBarTime = history.getPreviousBarStart(dailyEET, history.getStartTimeOfCurrentBar(Instrument.EURUSD, dailyEET));
List<IBar> askBars = history.getBars(Instrument.EURUSD, dailyEET, OfferSide.ASK, Filter.WEEKENDS, 6, prevBarTime, 0);

Regard.

Dear Support Team,

This is a problem with the customized period Period.createCustomPeriod(Unit.Day, 1, JFTimeZone.EET). It appears that the customized period does not work with the function history.getBar() in the REMOTE mode.

The part is my code is below:
     framePeriod=Period.createCustomPeriod(Unit.Day, 1, JFTimeZone.EET);
     //framePeriod=Period.DAILY;
     dailyBar=history.getBar(Instrument.EURUSD,framePeriod, OfferSide.BID, 3);         
     console.getOut().println("Daily Bar test: High="+ dailyBar.getHigh()+", Low="+dailyBar.getLow()+", time="+sdf.format(dailyBar.getTime()));


This code is working for both DEMO and LIVE only in LOCAL mode, but not in REMOTE!!! The code crashed with NullPointerException at history.getBar(...).

The full code is attached.
