Hi there !
We're sorry for the delayed answer ! looks like your post was forgotten !
Alright,
Such setting is only available at the level of the charts (either Historical tester or live Jforex charts) they are not available in the API or in the indicator's parameters when computed in your strategy. If you don't want to wait till the candle's expires to have your indicator's output then the solution is to make it working on lower trading period or even on tick method
