I agree to an extent with @Whack_Attack, I don't think it is possible to become a trader in less than two years.
The thing is the markets are cyclical and the "Business cycle" is between 4 and 7 years as a rule, so after 2 years, you will not have experienced all market conditions, so you cannot know what to expect.
Some "Scalper types" may disagree, but I still can't do that with any great degree of success.
How long does it take ? - well I just threw away my spreadbetting statements from 2002,2003 and 2004 and for most of that time I was sitting in my study reading and back testing and betting, having decided to give up work and do this full time because by then, I thought I knew enough.
PS I have a degree in a sciences related subject from a good Uk University at a time when only 10% of kids made it to uni - so I'm not stupid, and a lifetime of experience to call on. I read somewhere that it costs the big boys £100,000 + to "Train a trader" - so make no mistake this is not easy !
