Hey Ilan,
How come the EAs have SL above 500 pips?
If you have created such EAs, then you should expect that the trades might go on such a loss. As I show in my courses, I don’t go above 100 pips because it is likely that the hourly trend reverses after 100 pips movement in the opposite direction.
I avoid giving suggestions and trading advice, but if you have set such SL for some reason, you should be expecting it and handling such positions…
Anyway, I would keep them in my account is big enough, and if you did a mistake with such a huge SL, you can also hedge the positions (buy at a lower price so the average price will be lower, and you can recover quicker).
Regards,
