I was stupid enough not to notice that today was the last trading day for the QG March 2007 contract. (It's this special situation that QG has its last trading day always four business days before the beginning of the contract month..). Delivery type for this contract is financial / cash. So, now I'm still short QG and I wonder what exactly will happen to my IB account next week on the final settlement day. Do I have to expect any problems or will they just do a normal cash settlement as if I had sold the contracts on a usual trading day? Any help with this is appreciated!
