I bought the Spy jan 16, 91 Put on tues 16th. It gained .30 after todays drop. I was confused why after looking at the chains for the same expiration why almost all of the OTM puts lost value today after Spy was down almost 2%. I thought that as the price moves closer to the strike, granted its still a few weeks from expiration, that the option should gain in value. I don't know what the price of the options were during the trading day, I checked them today and looked at all of the closing prices. Don't know if that is a factor. As you can see I am rather new to options but I am learning, reading, and taking some chances. Thanks -Ray ps, just quick question... can you chart option contracts?
