sell or buy placed by Expert in demo?

 

I have a demo account with MT4. Recently I noticed that some of my buy and sell orders were placed by "expert", followed by an expert id. I have never authorized anyone to do that for, neither did I enable the EA authorization. Because of this erratic "expert", I have been losing money. Have been trying to find the answer online but no luck. Hope someone can solve this mystery for me. Thanks.

 

Expert can only trade if it is placed on a chart logged into your account.

  1. You did it; go to the data folder\MQL4\experts and delete any ex4's you don't recognize and restart the terminal. Data Structure in MetaTrader 4 Build 600 and Higher - MQL4 Articles 17.02.2014
  2. It's a demo account, create a new one.
