Of all the option strategy and trading adjustment books I have read, the most informative have been 'The Option Trader Handbook' by Jabbour and Budwick and Mcmillan's 'Options as a Strategic Investment'. I've also read Cottle's books. I would appreciate any suggestions as to further study. I've read a ton of options books, but none have the amount of additional trading adjustments that the former 2 do. I'm sure there is another book out there for future study that is in their same class. And just for the record, I'm not looking for the grail, I just enjoy studying different authors perspective of market action. I appreciate anyones advice.
