Indicator on other time frame

[ralph.ronnquist]

How do I apply an indicator to a secondary time frame chart? I thought
it was merely to do it like the following pseudo code:

Add(other time frame); // becoming the BarsArray[1] Bars object
Add( indicator( BarsArray[1],... );

But when running that, it tells me I can't use BarsArray in the Initialize method.

I have browsed the manual pages for a solution, but not been able to find one. Please help me.

Unfortunately indicators only run on 1 (!) data series. Only strategies support multiple data series (which wold allow you to code your issues there).

Hmm; I did try this within a strategy.? My logic involves one indicator on the main chart, and another indicator on a secondary chart. Basically it involves two charts with separate indicators that I want to read off and combine through this magic formulae.

- unfortunately you can not cross reference indicators on different charts
- please check out SampleMultiInstrument strategy for how to work with indicators on different series

Thanks. Good. Right. So I just apply the secondary chart indicator on the fly. I assume this primarily means that my strategy does not receive events from the secondary indicator, which is totally fine.
But, are there performance implications? E.g., is the secondary indicator re-created for each usage?

Indicator on secondary series has the same performance impact as indicato on primary series. Just give it try.
