Which is the safest between the forex brokers?

As far as I know, Interactive Brokers have licence. But they are quite serious and their requirements are fairly high. You should invest $50.000 to trade with them. Still, they are well regulated and trustworthy.

If you look for something simpler… Read about Oanda, it’s a canadian company. They can be trusted too.

FXCM is no more working on the US markets, But I assume you already know it.

Well, to be honest there are lots of quite safe brokers. But you should understand that it is quite subjective opinion. I think that the key is a reliable broker. Everyone knows that. I recommend to have a look at forex rating https://www.forex-ratings.com/ I used to work with two years. They guarantee safety and you can be sure there won`t be any fraud. Good luck. Hope it can be helpful
