I wasn't aware this was true for index options, so thanks MTE. Futures options on barchart and stock/etf options on yahoo are very easy to navigate through when looking through intraday or daily data for options. Option data including volume/OI/price/ daily fluctuation, for each individual strike in all listed months. etc. I'm pretty sure both of these sites do not have the same detailed data for index options. I've looked at a lot of sites for the same information for index option including (CBOE, NASDAQ, OIC, and a number of others). I've yet to find any webpages that lay out Index option data in a simple format like yahoo and barchart. You have to this or that or download a spreadsheet or .flv or whatever. Is there a similar site/s for index options that's easier to navigate daily information for index options? Thanks
