i am signed up, i love it, but it doesn't show volume history. I was looking to get volume for the last few days of trading in a particular option.
Oh, yeah. Only Livevol Pro has that. Two years of history for all options and underlyings (pre/post market) by strike, exchange with level II. Sorry Is there something in particular you wanted? If it's small I might be able to help...
I don't know how accurate it is but the following provides 3-4 weeks of closing B/A, volume and OI. http://www.crimsonmind.com/options/HistoryData.aspx
