The firm I just joined has an S&P squawk box blasting all day long in our trading room. I was curious as to the question that does the big contract have a tendancy to lead the E-mini or not. I have found the squawk box a bit annoying and have been thinking about just putting on some head phones on and forgetting about it altogether. I mean the mini's do 4 times as much dollar volume, and why would Goldman or any other broker choose to execute in the pit when everyone in the world is hearing ," Goldman buys a 100." Yeah they are probablly selling 500 in the minis every time you hear this. Just curious if the big contract leads or not and how useful following it really is. I have not put the 2 contracts side by side yet and compared because I have enough on my screen already but I was thinking about it.
