Hello support,

I set in platform platform and chart shift time (UTC + 2). If I open new chart from strategy hourly and daily bars are OK.

But four hour bars are bad. They starts at 2, 6, 10 .. hours, but they should start at 0, 4, 8 hours.

I tried to open hour chart and change (from strategy) to 4 hour, but change doesn’t works. I must change it manually.

Please help. Thank you.

IChart Chart = null;
//
IFeedDescriptor FdDsc = new TicksFeedDescriptor( Instr );
//
FdDsc.setDataType( DataType.TIME_PERIOD_AGGREGATION );
if ( ChartPeriod.equals( Period.FOUR_HOURS ) ) {
FdDsc.setPeriod( Period.ONE_HOUR );
}
else {
FdDsc.setPeriod( ChartPeriod );
}
FdDsc.setOfferSide( OfferSide.BID );
//
try {
Chart = Context.openChart( FdDsc );
}
catch ( Exception Exc ) {
Exc.printStackTrace( Err );
OInfo = "===";
OInfo += MethodName + ": ";
OInfo += "Exception: " + Exc.getMessage() + "; ";
SES.fiout( OInfo );
}
//
if ( Chart != null ) {
Chart.getFeedDescriptor().setPeriod( ChartPeriod );
Chart.setDataPresentationType( DataPresentationType.CANDLE );
}
//

Hello support,

this problém is still bothering. Day bars have this problém too.

Thank you.

When chart is created from a strategy, timezone is determined by the timezone of Period parameter.
If strategy needs to open chart with timezone other than UTC, custom period object must be created.
To set custom timezone please use this code:

Period period = Period.createCustomPeriod(Unit.Hour, 4, JFTimeZone.EET);
        IFeedDescriptor feedDescriptor = new TimePeriodAggregationFeedDescriptor(Instrument.EURUSD, period, OfferSide.ASK);        
        context.openChart(feedDescriptor);
