Can one EA send a signal to another EA?

I was wondering if I could have an expert advisor programmed that would receieve a signal and have that signal sent to another expert advisor that would execute a trade.

Essentially I want to have 2 seperate programmers so the trade logic isn't discovered.

I'm currently using a free trade copier at http://www.mt4i.com/personaltradecopier.aspx.

It works really well!

Hope this helps

No,

I am looking to have 2 expert advisors programmed, 1 that sends a signal when a certain criteria is met and another that takes that criteria and runs it through it's own set of criteria and determines if a trade will be executed.
