street smart 的看 "how i trade options" by Jon Najarian. Book worm 的pick any.
Option just like stock, you don't need to play too much attention to all those delta, gamma, vega, theta, etc. Those are misleading. Unless you are a math magician.
Most important is look at the MOST ACTIVE STRIKE, HOW THEY BEING TRADED, WHAT MONTH BEING USED, VOLUME PUT/CALL RATIO, OI PUT/CALL RATIO. |
