Just finished Positional Options Trading and agree completely with your comments on Sinclair. Easy to read, good blend of down to earth simplicity with nitty gritty complicated subjects/formulas, great sense of humor etc...Sure
Sheldon Natenberg - Option Pricing and Volatility
Jeff Augen - The Volatility Edge in Options Trading
Jeff Augen - Trading Options at Expiration
Euan Sinclair - Positional Option Trading
Euan Sinclair - Option Trading: Pricing and Volatility Strategies and Techniques
Dan Pasarelli - The Market Taker's Edge
Anthony Saliba - Option Trading Strategies for Directionless Markets
Allen Baird - Option Market Making
I'd say these 8 books will pretty much give you a pretty solid understanding of trading options, their risks, how structure works for various spreads, the concept of trading volatility, and a good understanding of what the market makers or those taking the other side of your trades are doing. If you want to trade expiration day stuff the Augen book is pretty solid.
Natenburg is probably the first author to put it all together. I'd say Sinclair is probably my favorite I think he has a gift for explanation and a certain amount of wit and humor in his writing. Saliba and Pasarelli are former floor traders as well as Baird a former market maker.
not sure what to go with next but leaning towards The Bible of Options Strategies by Cohen or Option Pricing and Volatility by Natenberg.
Will be referencing your list for a while to come, thanks agin.
