May I ask you a question: Many of the options I traded were thinly traded with wide bid/ask. Normally I just aimed for mid point between bid/ask. Was I wrong to aim for mid point?
Correct. Mid point is what your broker wants you to do and it's wrong most of the time. First look at the opposite call/put. The spread should be narrow and that's the real bid/ask relative to extrinsic. Then there is the real value which you will learn over time. Look at the ranges over time and Where it could go and what is your target. I'm Long options cause there are many premium sellers that short blindly Low vols. Think about trading stock and buying opposite call/put and take advantage of put/call parity. Then you will find the real/fair market.
