Hi!
I have a question. Is it possible to usubscribe from instruments in onTick() method?
Not to filter them by "if (instrument == this.instrument)". I want to get ticks only from
single instrument, to force Strategy calculate faster.

If you run REMOTE strategy all instruments are subscribed explicitly by your strategy. So it's up to you what instruments subscribe to.

If you run LOCAL strategy you can see the all subscribed instruments in the left pane named "Instruments". Right mouse click -> Remove All

Thanks a lot, compatriot! One question more.
Can i get bars in onBar() method only from one single time frame? Strategy gives me a lot of time frames, which i don't need.

No, you cannot.

Simple filter will have an insignificant cost for performance.
