Hello Ilan,
Glad to hear from you again. Make sure you have enough margin in your account. And this you can do by lowering the trading amount.
How many EAs and what lot size do you use for 1.5k account?
I think you can do easily 10-15 EAs with 0.01 or 0.02 lots. If you go with higher lots you would probably miss some trades because of the margin.
Regards,
