Dear support team,

When starting strategy using "Remote Run", in onStart method can not get TICK from history.

@Override
public void onStart(IContext context) throws JFException {

    ITick tick = context.getHistory().getTick(instrument, 0);
}

In this case TICK is NULL.
Please, can you check it?

Hi:

Try to get tick information after the strategy has subscribed the instrument. If done forget this post.

Thanks for quick reply.
In real strategy I try to get tick after subscribing to instruments.

Hi:

Sometimes subscribing can take some time...
You can try to see if instrument is subscribed before try to get tick information.

I use code below to subscribe to instruments

    context.setSubscribedInstruments(instruments);

    // wait max 1 second for the instruments to get subscribed
    int i = 10;
    while (!context.getSubscribedInstruments().containsAll(instruments) && i >= 0) {
      try {
        console.getOut().println("Instruments not subscribed yet " + i);
        Thread.sleep(1000);
      }
      catch (InterruptedException e) {
        console.getOut().println(e.getMessage());
      }
      i--;
    }

I do not see any reasonable explication to be unable to get tick information if you try to get it after that code...
lets see if support has anything to say.

EDIT: instead of context.getHistory().getTick(instrument, 0); try with context.getHistory().getLastTick(instrument); it gets last tick received by the strategy. current tick (shift 0) sounds a litle ambiguos to me as at that time the method is called exist the possibility of no existing tick.

Both methods return NULL.
Ticks in History available only after onTick method execution.

Try this snippet for your onStart() method:

        //wait max 10 secs
        for (int i = 10; i > 0; i--) {
            try {
                Thread.sleep(1000);
            } catch (InterruptedException e) {
                context.getConsole().getOut().println(e.getMessage());
            }
            if (context.getHistory().getLastTick(instrument) != null) break;
        }
