There is no new TickBar from ITickBarFeedListener. Code works in 2.9.2 as follows:


barSize = 16;
m_Context.subscribeToTickBarFeed( Instrument.AUDUSD, OfferSide.ASK, TickBarSize.valueOf( barSize), new ITickBarFeedListener() {
@Override
public void onBar(Instrument instrument, OfferSide offerSide, TickBarSize size, ITickBar bar) {

Please provide the strategy that replicates the case.

in OnStart():

/////////////////////////////////
// AUDUSD TickBar
barSize = 16;
m_Context.subscribeToTickBarFeed( Instrument.AUDUSD, OfferSide.ASK, TickBarSize.valueOf( barSize), new ITickBarFeedListener() {
@Override
public void onBar(Instrument instrument, OfferSide offerSide, TickBarSize size, ITickBar bar) {
if ( instrument != Instrument.AUDUSD)
return;

int instrInx = ( int)Utility_GetInstrumentSN( instrument);
//int TradableOn = m_TickBarSyncControl[ instrInx].TradableOn;
if ( m_TickBarSyncControl[ instrInx].BidDone){
m_TickBarSyncControl[ instrInx].AskDone = false;
m_TickBarSyncControl[ instrInx].BidDone = false;
m_TickBarSyncControl[ instrInx].NewBarSyncCount = 128;
m_TickBarSyncControl[ instrInx].AskBar = bar;
m_TickBarSyncControl[ instrInx].FlushCache = true;
}
else{
m_TickBarSyncControl[ instrInx].AskDone = true;
m_TickBarSyncControl[ instrInx].NewBarSyncCount = 0;
m_TickBarSyncControl[ instrInx].AskBar = bar;
}
}
});
m_Context.subscribeToTickBarFeed( Instrument.AUDUSD, OfferSide.BID, TickBarSize.valueOf( barSize), new ITickBarFeedListener() {
@Override
public void onBar(Instrument instrument, OfferSide offerSide, TickBarSize size, ITickBar bar) {
if ( instrument != Instrument.AUDUSD)
return;

int instrInx = ( int)Utility_GetInstrumentSN( instrument);
//int TradableOn = m_TickBarSyncControl[ instrInx].TradableOn;
if ( m_TickBarSyncControl[ instrInx].AskDone){
m_TickBarSyncControl[ instrInx].AskDone = false;
m_TickBarSyncControl[ instrInx].BidDone = false;
m_TickBarSyncControl[ instrInx].NewBarSyncCount = 128;
m_TickBarSyncControl[ instrInx].BidBar = bar;
m_TickBarSyncControl[ instrInx].FlushCache = true;
}
else{
m_TickBarSyncControl[ instrInx].BidDone = true;
m_TickBarSyncControl[ instrInx].NewBarSyncCount = 0;
m_TickBarSyncControl[ instrInx].BidBar = bar;
}
}
});

We couldn't find any problem with ITickBarFeedListener and TickBar data feed.

Here is example strategy that prints received TickBar. It works as expected.

package testing;

import com.dukascopy.api.*;
import com.dukascopy.api.feed.ITickBar;
import com.dukascopy.api.feed.ITickBarFeedListener;

public class TickBarTest implements IStrategy {
    @Override
    public void onStart(final IContext context) throws JFException {
        context.subscribeToTickBarFeed(Instrument.AUDUSD, OfferSide.ASK, TickBarSize.valueOf(16), new ITickBarFeedListener() {
            @Override
            public void onBar(Instrument instrument, OfferSide offerSide, TickBarSize size, ITickBar bar) {
                context.getConsole().getOut().println(bar);
            }
        });
    }

    @Override
    public void onAccount(IAccount account) throws JFException {
    }

    @Override
    public void onMessage(IMessage message) throws JFException {
    }

    @Override
    public void onStop() throws JFException {
    }

    @Override
    public void onTick(Instrument instrument, ITick tick) throws JFException {
    }

    @Override
    public void onBar(Instrument instrument, Period period, IBar askBar, IBar bidBar) throws JFException {
    }
}

We replicated the problem. This will be fixed in next API release. The release is scheduled next week.

Thank you!
