Can you control a trade from multiple chart windows?

 
I have a trading system that i have purchased, (I don't have the code) and I would like to add a trailing stop automation to the trades.  Can I have the purchased autotrader initiate the trade and then have on another chart window, have another expert advisor monitor the trades and initiate the trailing stop once the trade is placed?
 
Yes, it is possible

Yes, it is possible

would you have an expert written to handle this?
 

Excuse me, I misunderstood...

I think a previous answer from Metaquotes indicates that the Trailing Stop built in to MT4 can NOT be activated by code.

However, a second expert could monitor the trades and prices and set and change the stop price as necessary.

No I do not have an expert/script written to specifically do that.
