Trust me, margin calls are very important and you can’t just ignore the fact that your account is about to go down like that.
I think a lot depends on the broker. Never go with the one that doesn’t give you a margin call when it’s time.
Well, in my experience, I have traded with IG, Fxview, CMC Markets and their services seem to be okay. It is very important for me to trade with regulated brokers so I generally go with them.
