Is is possible to make a trade button that trades on multiple instances of mt4 ?

As the title indicates my question is this:

Can I make a buy/sell/close button that can trade on multiple instances of the platform instead of doing some copy trading type thing ? 

Please advise
Thanks

Yes, but you will have the code a communications protocol between the various instances to achieve that.

Alternatively you can use a trade copy product from market place.

As a suggestion, instead of coding your own.

Old post and delayed response but thanks to all. 

I think coding this on my own and my level of knowledge may be too much for me to handle. 
Perhaps a market place service is in order. 

Thanks
