I learnt the hard way - busting many accounts! Never start off with trading with money that you can not afford to lose.
A good starting point is ask yourself why do you want to trade? I say this because many people start off trading because they are frustrated in their daily jobs and think this is an alternative. If you have to be successful in this business you got to love it. you need to understand losing is part of the game.
if you have passion towards trading, then the next thing is to list down your goals, find out what sort of trading style you prefer, what will suit your personality.
There might be plenty of books around - but I have read the following and found useful.
John Carter's Mastering the trade, Trading the Zone by Mark Douglas, Definitive guide to position sizing by Van Tharp for Money management, Howard B Bandy's books ( i might be biased here since I use amibroker. Prototyping your ideas quickly will really help.)
Do not forget the psychology part in addition to risk management!
Looking back, I might have fast-tracked if I had a mentor (someone reliable and has a track record - better if you know that person in real

) at the beginning. I got one who happens to be my friend a bit too late.
Good luck!
