I put 15 sell limit orders in last night around 10pm and then decided to cancel which j find so about 30 mins later after changing my strategy. It was pending cancellation up until 6am this morning. I was panicking all night that it wouldn’t cancel in time for FTSE open.
I too refreshed, logged out and hoped it would sort itself out which it eventually did.
Thank god the open was 10 hours after I closed the order.
