While that was pretty cool to see, i'm really still not convinced the footprint chart is that useful. It almost seems to me you can get the exact same info from multiple time and sales windows. Regular time/sales, time/sales filtered to only show trades at the bid with X number of contracts, then the same thing for the ask.
I'm pretty much done with this trial of market delta now. Pretty much agree with every review i've read of it. Its pretty interesting but not interesting enough to warrant the price they charge for it.
