Huytq, as I said above, I recommend you read Alex Elder's books as part of your starting-out reading. From there the sky's the limit; my trading library currently has over 100 books and I've read about 2/3 of them so far with the rest in the queue.
One that I was skeptical about is "Reminiscences of a Stock Operator", which seems to be on everyone's "must read" book list. I doubted that a book published in 1923 would have much relevance or hold much interest for us "modern" folks. But I finally picked up my copy and read it.
Conclusion? Read it. Read it as soon as you can.
When you see that in order to produce, you need to obtain permission from men who produce nothing - when you see that money is flowing to those who deal, not in goods, but in favors - when you see that men get richer by graft and by pull than by work, and your laws don't protect you against them, but protect them against you - when you see corruption being rewarded and honesty becoming a self-sacrifice - you may know that your society is doomed. - Ayn Rand
