As of right now the pit is more liquid on a weighted basis. The pit trades about 3 times more dollar volume then Globex. However as recently as a year ago it was around 6-1. Also the pit trades in dimes so there is an opportunity to get filled between the ES quarter point spread. Also commissions on 10 S&P's are around half(at least) of what it costs to trade 50 minis. If the screen is 50 up you can rest assured the pit has got 10 lots, especially in these crummy ranges. Locals are very accommodating these days.
