Quote from Pa(b)st Prime:
The ECBOT is. Yesterday 45,972 Wheat traded on the screen vs. 26,778 in the pit.
Most spread business still goes to the floor. I'd reckon 15,000 of that pit biz was spreads or outright back months.
I trade both venues and the fills are great in each. A couple of months back while placing an options order with the floor (SUPER tight markets in Corn opts) I also put in 5 Bean sales with the pit. Lo and behold I was filled on a 1 tick print HOD. I might not have been filled on ECBOT.
