Hard to say. First try to make a small research and get some knowledge of course. But if you plan to go into Forex seriously, I recommend to start from reading this review fx-list.com/broker/forex-com because it worked pretty well for me. I like good conditions for investments and an excellent customer support. Moreover it is always better to trust your broker and be sure it wont let you down. Hope it will make sense for you
There really isnt a number one broker. Many brokers are good and alot of them are bad. i can only tell you from experience from the ones that i have used. i started out at IG and oanda, but i found their platforms slow and the leverage is low. So i switched to a broker with a bit more leverage and now i currently use Hugosway and ic markets, much more to my liking, faster platforms and websites too
