Don't buy any course. You got all you need on babypips.com for basic knowledge, the rest will be you against you. What I mean by that is you'll have to trade with a demo account while you're learning. Once you feel comfortable, you can do a small deposit in a real account and practice again. You'll blow the account most probably, then you're going to repeat the process. Blowing accounts after accounts until the pain makes you change your bad behaviors one at a time. Forex trading is the hardest shit I've done in my entire life, don't expect to make any money soon or later. The best course you can get is practice and learning from your mistakes, don't get scammed by those online marketers.
