You want to watch a recording of a past day? Why not sign up for a demo of a platform that has a DOM. Watch it live.
What Robert said, or if you really want some videos you can watch a few old Futex Videos on youtube (not 7 hours, but up to 1 hour per video), as a bonus you get lots of good info from Brannigan Barrett (now Axia Futures). Example:
I closed my Open E Cry account when they started charging for the DOM and for inactivity. All the stuff I read now makes me not even know where to go to get data.
@IronFist Suggestion: AMP Futures. Open account with $100. They will charge mandatory $10-$15/mo for CME data feed bundle. Test/demo free platforms, web-based and/or desktop. Demo capability/duration may vary between platforms. When ready, fund the account so you can trade!! BTW: smart move leaving OEC.
