So I was trading CL (Dec) this morning. TWS informed me that I could not trade this contract as it was too close to physical delivery. I looked up CL on website, it says that it halts trading around the 22nd. Oh well, I can adjust. Then I noticed, January was 80Â¢ lower than Dec. So if I were to roll, I would be hit with 80Â¢? Guess I still have a lot to learn.
