If you want to learn forex trading with a broker then maybe something wrong! Thinks it again, actually, what do you want, good broker or good education? There are (internet) many free resource and course, you may start with them such as Investopedia, babypips also earnforex, next you can choose your broker to trading (but must begin you trading life with demo trading).
In another case, if you want to learn from brokerage website, then you maybe go forex.com, fxtm, admiralmarket, fxcm, ig markets and +++.
Note: all are mentioned resource only for learning, not a website or broker suggestion.
