How to read Heikin Ashi indicator data in a Cbot ?

Hi there!

I'm using this Hekin Ashi indicator from the repository: https://ctrader.com/algos/indicators/show/60

I want to use the open and close values from the indicator in a cbot instance to make trades based on the color ha candles.

I'm using the next cbot script (at the end) it's found on the forum from an old heikin ashi help topic

And I get this error while I want to read open or close values from the indicator thought this line Print(HA.Result._haOpen);

Error CS1061: 'cAlgo.Indicators.HeikenAshi' does not contain a definition for 'Result' and no extension method 'Result' accepting a first argument of type 'cAlgo.Indicators.HeikenAshi' could be found (are you missing a using directive or an assembly reference?)

I've tried to look on the forum for similar topics but they are pretty outdated and the advices from those topics not works in my case, what I'm doing wrong?

The reference it's checked from cbot.see the below screenshot.

Have a nice day!
