EA & Brokers

Hi.
I wonder is there any way for broker to see if I open an order with EA or manual? Maybe there is some kind of flag that if order executed by EA then send to broker?

Yes, I heard, they see it.

I can't point you to a specific post, but I've heard from multiple sources that a broker can indeed tell which orders are manual and which are placed via EAs.

This is strange. After such long time, now I can answer my own question with 100% confidence. Short after this question was raised I worked in few different respected brokers with MT4 servers.

I can say that broker can not see if trade is opened manulaly or automatically, it can only forbid trades from EA, or allow. There is no flag that shows automatic trades. Brokers usually identify that trade is opened by EA is by comments. Usually manual opened trades have blank comments.

Wow! Thanks for coming back and letting us know. Which brokers did you see this at? It is very interesting.
