Is it possible to use HeikenAshi in a Strategy?

[crmcwi]

Guys,

I made a copy of the HeikenAshi indicator so I could set the colors on my chart.

I can Add() it, but when I try to call crmHeikenAshi.HAOpen[0] or crmHeikenAshi.Values[0][0] and run a strategy, I get a very curious error message I had not seen before and I've Added() lots of other indicators:

Error on calling 'OnBarUpdate' method for strategy 'MamaHeikenAshi2': The indicator 'crmHeikenAshi' is intended for visualization and can only be used on a chart.

Can someone explain what causes this and how to enable this indicator to be used in a strategy please?

Guys,

sorry. I'm leaving this here for any others who have this problem.

In OnInitialize() the original code had this internal variable set to true.

do this and you can use the indicator in a strategy:

ChartOnly = false;
