Server Spy?

 
Hi

I was wondering, can a broker that is running metatrader server somehow see the code that your expert advisor is running on his server?
 
"running on his server"

Maybe

But I suspect your code is not "running on his server", it is "running on your client"

In which case the answer is no

Unless the MT4 client software contains spyware for that purpose, which is somethng we have
to trust is not happening.
