Hello, I have a situation where a futures contract did not execute. It was placed for âMarket at Openâ. The order was accepted but the order was cancelled directly before the market opened. IB have contacted the exchange and are looking into it. Assuming the best intentions on the part of IB, how can this issue best be dealt with. Assuming it is recognized as an error either on the part of IB or the exchange, how can something like this be priced? The futures have since gone up in value a lot. Any comments would be very welcome.
