I'm just getting back into futures trading and find that electronic markets have substantially displaced the pit, but I want to trade pit hours. Today I placed an order to buy sept CL market with a good after time of 9:00:20. IB executed it at 9:00:20 and I got a fill of 139.47 and when I look at the NYMEX price chart it does look like this is an appropriate price. I timed this to coincide with the start of open outcry trading which according to the NYMEX web site is 9:00 am EDT. According to NYMEX the open outcry high was 139.00 http://www.nymex.com/CL_spec.aspx I doubt the price spread in electronic trading could have been that wide. I wonder if the open outcry session really starts later. At one time some markets opened the contracts in rotation, but I never heard of this for CL. Perhaps NYMEX lied to me and open outcry really starts at 9:30 as I have just found on IB's web site. Of course IB says the close is 16:00, but I thought it was sooner. Can anyone clear this up?
