Reading signals from a custom indicator

I'd like to be able to access the values from a custom indicator from another an EA. I read in this article: http://articles.mql4.com/197 that you can use an indicator as an embedded MT indicator's data source. I tried that and I didn't get the options they showed in the picture in the drop down list. I only got Open, Close, Median, Weighted, etc. But that wouldn't do what I want anyway since I want to access my custom indicator's plots from another indicator. I'm pretty sure there is a way to do this but I can't find out how. I basically have one indicator that generates 1 for long & -1 for short and I want another indicator to read those signals and base trades off them. Help appreciated.

I read through your post a couple times and I'm still a little confused. It sounds like you want to use a custom indicator in an EA, but you say that you want to use a custom indicator in another custom indicator. I tried to visit the link you provided, but was unable to load the page.

If you want to use a custom indicator in an EA, you probably want to use the iCustom function, it's designed to do exactly that. Look it up in the MetaEditor documentation.

If I didn't answer your question, please post again and clarify a bit.

Thanks. I think that is exactly what I'm looking for!

But now I really would like to do the other thing I posted about. The link works for me but I will try and clarify.

I'm attaching the image of the dropdown list from the above article and the screen shot from my dropdown list. The difference is that it's not giving me the option to apply a Moving Average to an existing indicator. In my screen shot it looks like the items are cut off but that is the last item. I want to be able to select "Previous Indicator's Data" and "First Indicator's Data" but they aren't options for me.

Are you just double-clicking the moving average indicator to add it to the chart? To get the additional options in the dropdown, you can't double-click to add it, you have to drag it onto the window with the indicator you want to apply it to. I hope that makes sense.

ok. thanks. that seems to work.
