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.
