i have traded oex index options in the past so i am familiar with them but most of you guys talk about spy and various etf's.To be honest i dont know shit about spy or the etf's but i gather spy tracks the sp500 and is similar to dia?Also what is it that guys like about spy's and the etf''s vs other derivatives?Do they mess around with premiums a lot?Is the time decay pricing sketchy?OEX can be quite hair raising at times.
