I have the same experience with EA, it is not good. when I use this, at first they generate a good profit. after the last few days they made a big loose. it's very painful as a forex trader. if I make it loose by hand than it is not a fact. when the machine makes this zero your balance, it is not good. and there are many EAs that can blow up your account quickly. But we can control it to minimize losses or avoid possible MCs. Find the best EA with good money management in it. Even our small profits can remain profitable for a long time. Just paste it. It's so easy it's not that hard to do.
