I have a few questions that I’m hoping you will help me clear up. First, will a broker close a trade that has been open for a while? And second, will one EA close a trade made by another EA that is no longer running?
The only way that I could think of your broker closing a trade is if you hit a margin call or maybe you had a stop or take profit that you forgot about.
If the EA that is not running opened a trade then you took out that EA with the trade still open…then yes, the second EA would probably close that trade if it was a trade in the opposite direction. That is if you are in the US and/or your broker does not allow hedging.
