How can we create Heiken Ashi Charts in Wealth-Lab?

Heikin, not Heiken. (I corrected the post title.) Perhaps this explains why it didn't come up in Search? (Example: Can Heikin-Ashi replace standard candles?)

Check out the QuickRef example for Bars.SaveToFile.

Heikin Ashi in Community ChartStyles, no coding required:

Community ChartStyles library

Is there a way to access the Open, Close, High, Low values of heiken-ashi just like how we can access the default values ?
Does changing the chart style to Heiken Ashi automatically modify the OHLC values ??

Basically see post #2 right above for answers. Also, you're making the same typo as topic starter. If you would've noticed my correction in post #2 your forum searches might become more productive.

1. For a code that creates Heikin Ashi candlesticks which you can access, see the QuickRef example for Bars.SaveToFile. Did I say it in this thread already? :)
2. No but the code sample I referred to above does it for the virtual plotted symbol.

While I'm at it, you'd probably have to change this line to target a different directory; Windows won't let you save to the system drive's root or Program Files w/o WLP running with elevated permissions:

Got it that makes sense. Thank you for correcting the typo, will keep that in mind.

Yes, that example should be corrected. You can save it to the TEMP logical device instead:

There's a couple of Heikin-Ashi oscillators you might also find interesting. I use the latter one myself. It's somewhat predictive.

Please note that a breaking change to HACOLT will take place. Since this is slightly offtopic to discuss here, more detail in this forum thread: S&C 2012-07 | HACOLT indicator (Vervoort).

FYI

TASCIndicators v2019.03 is out with the modification to HACO and HACOLT. Note that this is a breaking change i.e. backtest results may change.
