could you please consider including a function that returns the number of filtered bars between two times:

int getBarsCount(Instrument instrument, Period period, OfferSide side, Filter filter, long from, long to);

Thanks a lot,
RR.

Please take a look at getBars(...).size()

yes, sure, that's how we do it at the moment.
But it comes with some resource overhead. That's why we thought it might be good to have a function that does not return a list of bar objects, but only the number of bars.

Best, RR.

You can use readBar() method and cound bars in listener. This way it will not keep bars in memory and it's safe to run with long periods
