I don't understand why onBar() is called 4 times when the bar is closed.

Here is my onBar() method. It simply outputs HIGH of the bar. period is 15 minutes.

public void onBar(Instrument instrument, Period period, IBar askBar,
IBar bidBar) throws JFException {
if (period != this.period) {
return;
}
console.getOut().println("high of the bar: " + bidBar.getHigh());
}

And here is the output of the method:

13:15:01 high of the bar: 81.425
13:15:01 high of the bar: 0.86664
13:15:01 high of the bar: 1.66784
13:15:00 high of the bar: 1.48551

What do all these values mean? The correct one was the last one: 1.48551

Sorry,

I've got it. If there are several instruments opened in the workspace the method onBar() will be called for each of them.
