I have been following the strategies in options trade quite some time. In range bound market, most of my friends do, albeit with greater investment, selling options of both call and put strikes, and since october 2012, the trades are giving around 90 points per pair. On the other hand, holding options in naked fashion heavily dries up the premium. Can any one suggest how to initiate trade based on Intrinsic volatility numbers displayed in the options table and correctly interpret with some illustrations or suggest any other safe strategies
