In any bar we gets many number of updates/Ajdustment/changes.
How come I know in IStrategy.onBar event that this particular call is for particular bar(time period) and nextone ll be for new bar/timeperiod.

I tried above using following code

Period oldPeriod;
public void onBar(Instrument instr,Period pr, IBar askbar, IBar bidBar){
      if(oldPeriod != null && oldPeriod != pr) {
            System.out.println("New bar started");
      }
      oldperiod = pr;
}

But it is failing in 30 minute and 1 hour chart, as it returns 10 sec period on each event.

How to resolve this issue please let me know.
It is very critical for us.

I am having the same issue with onBar( ) period stuck at 10 sec. I only have 1 chart and changing that doesn't work. How do we set the period for onBar( ) in IStrategy?

hi -i have got exactly the same question:

how to arbitrary set the relevant period for the onBar function?

I figured it out. onBar( ) runs on every new bar on every period. So you need to check if the period is the one you want as follow.

In main class:

    @Configurable("Period")
    public Period period = Period.ONE_MIN;

In onBar:

    public void onBar(Instrument instrument, Period period, IBar askBar, IBar bidBar) throws JFException {
        if (period != this.period) {
            return;
        }

This is actually a good thing.

Hi,
Please note that, data will arrive for the each subscribed instrument.
