Okay, I know you’ve already gotten a lot of responses so far, but I actually did it for a short time. You can read about my experience here:
[Forex a Great Hobby, But Not a Great Job]
It’s a bit negative, but things have changed since I wrote that post. If I were to give it another go, I would definitely go prop firm. The two best that I know of are Maverick and Lux. In my estimation, you will need at least 100K. Prop firms have it if you are willing to learn and put in the work.
All the best in your career as a trader.
