I know footprint works with futures ( ES, 6E, CL ) ie all those on CME, COMEX etc but what about stocks on NASDAQ, NYSE, and AMEX. Does footprint work for individual stocks? I know of the three exchanges I mentioned above, NASDAQ, NYSE and AMEX that one or two of them don't really have the ability to subscribe to level 2 order book. I think it is AMEX but I can't find the info. Should nasdaq have a level 2 subscription. Can footprint charts be built for stocks and if not - why not? Doesn't programs like market delta, sierra chart numbers allow for the footprint on stocks? ''.
