This is just my 2 cents.
If you want to learn forex or trading in general have no or very limited knowledge of technical analysis then I recmmend these books as a general overview.
1. Technical Analysis of the financial Markets by Murphy
2. Japanese Clestick Charting Techniques by Nisson
After you have read those books then open a
demo account try to apply what you have learned so far. Then if the confidence is growing open a live $100 dollar account I believe OA allows you to do that then deposit the account with $100 increment if you gain 20% of your initial deposit never deposit another amount if your initial deposit shrinks - you have to rethink your strategy do some tweaking.
By the way experience is the best teacher don't stop learning spend as much time as possible to learn it.
