I've tried to read his books, but his style of 8 pages of verbose with 1 chart of demonstration didn't resonate with me.
Larry's book is interesting, his writing is easy to read. He is basically against day trading, and everything he points out is to prove that day trading is the best way to blow your account. I agree with that, the shorter the time frame the harder is to make your trade to work.
I'm partial to Chapters 1, 2, 3, 5, 8 and especially 13 in LT Secrets to ST Trading. Seriously well 13 in particular anyway.
The last chapter from his book is missing. "Larry Williams was managing OPM during 1987 when he won the Robbins Trading Co contest. His returns for 1987 across all accounts showed a loss of $6,122,281, but his personal account that won the competition achieved a gain of $902,599."
