[amibroker] Tomasz or anybody know the answer to this?

["mleonsprint" <mleonsprint@xxxxxxxxx>]

I trade intraday and use Amibroker Professional, is it possible to
have a buy and sell signal based on a "foreign" function. So like
if $Tick does one thing I can ask it to buy or short the ES? Also 
tried "set foreign" and that didn't seem to work either.. Just 
thought I would ask if it was possible to begin with.  I created 
the "indicator" to double check it was giving the proper signals but 
once I made it to give a buy signal it wouldn't give any in the 
system tester when I backtested.

Thanks again for your help
