A few other you want to read/have on bookshelf-
Market Wizards (all) J.Schwager
Trading for a Living -Dr.Elder (lesser extent, his follow on work-Come into My Trading Room is pretty good).
Street Smarts -Linda Rashke
Of course T/A books abound-any of 10 basically good titles there/easy find at Borders, etc.
Trade Your Way to Financial Freedom -Van K. Tharp (also, to lesser extent- Financial Freedom Through Electronic Day Trading - is one by Tharp, and written w/Brian June as well. I realize the title sounds pretty cheesy-but there's a lot of good meat in it. Covers some interesting ground re: truly treating your trading as a business. Coverage here again about expectancy/position sizing/and risk mitigation is info you must have before doing this full time).
Stick w/authors who actually trade and you'll avoid a lot of nonsense...
i've only read a few books, so don't have something to compare them against.... the best has never been in print - school of hard knocks...
but setting that aside, absolutely must know western technical analysis (try "trading for a living") and how to interpret japanese candlesticks (Nisson's books, the original is sufficient). TR mentioned a book i'm going to try to track down. and one that isn't for day trading but an interesting read is O'Neil's How to Make Money in Stocks. There were a few out of prints on day trading i read long ago, Elect. DayTrader I believe was one (might be spelling name wrong here but, Freidrich & West?), much might not apply any more.
paper trade all you want to learn, but when you plunk the $ down... all the preparations can fly out the window. somehow it is different when real money is involved, so be fully prepared to pay the price to learn....
there's just something that no book can teach you.... only hours calculating ideas out with a calculator, hours interpreting real-time charts in various time frames, hours looking at L-2 which at times can be useful (more hours of looking for patterns in chaos)
