Quote from guy2:
Just read this which I thought was topical and relevant:
Ryan Jones is considered one of the trading industries "most complete traders". Starting his trading career at the early age of 16, he had traded nearly every major market and strategy by the age of 21. At the age of 26, Ryan signed a book deal with John Wiley making him one of the youngest authors ever in the field of futures trading. His book, The Trading Game, Playing by the Numbers to Make Millions is still considered to be the authority on the subject of trading and money management by many leading traders. Ryan's advanced experience and knowledge across many trading fields such as Technical Analysis, Option Trading, Money Management and the S&P have lead to several trading feats, including turning a $15,000 account into over $107,000 in less than 90-days short-term trading the S&P (real money).
