How do I use AddHeikenAshi

[alanlopen]

In my indicator I want to have some calculation based on HeikenAshi OHLC candles, so for this I include AddHeikenAshi() in ''else if (State == State.Configure)'' but I do not know how to fill the parameters of AddHeikenAshi(). I want the same instruments and the same timeframe as whatever the timeframe and instrument my indicator is applied to. So for instance if I apply my indicator to a chart of ES with 30min candles, I want the HeikenAshi OHLC candles for ES on the 30min chart. How do I do this ?

Hello alanlopen,

You can see an example of using AddHeikenAshi at the bottom of its help guide page:

https://ninjatrader.com/support/helpGuides/nt8/addheikenashi.htm?zoom_highlightsub=AddHeikenAshi

This method does not have a way to inherit the primary instrument so you would need to type in the instrument like shown in the sample.

Timeframes cannot be automatically assumed by any of the add data methods so that is something you also need to specify when adding it.

so how do i get my indicator to calculate form the heikin-ashi prices? for instance the taking the official RSI, and adding a feature of choosing (with an enumeration for instance) either the real price or the H-A price ?

Hello alanlopen,

To do that you would need to AddHeikenAshi so the script always adds that data. You can then make a enum property that is used from OnBarUpdate to determine which indicator value to use.

The AddDataSeries/AddHeikenAshi methods are not dynamic and cannot use variables so if you plan to use secondary data based on a user selection you still have to always add that secondary data and then make the choice of what series is used in your OnBarUpdate logic.

yes so it's not a solution. the only way is to calculte my own HA series in my script, using the real price which is always determined by the current chart.

Hello alanlopen,,

You could certainly do that if you wanted. The add data methods cannot be used dynamically so if you wanted to dynamically calculate something from the price you could make your own logic to do that.
