Hi there,
Your request was submitted for feasibility study and according to the indicator's outputs that is displayed as candles, the way it will be implemented in visual Jforex will be most probably a set of variables that retrieves the OHLC candle data. Prior to that, some enhancements should be made at the level of the back-end as Jforex platform it self is not populating the full data belonging to the Heikinashi indicator but just the drawings.
This will take time to be implemented, so we kindly ask you to be patient
Cheers
