IB TWS users: have you noticed that if you buy to open, you buy at the ASK price; but when you check your account, the unrealized profit or loss is not calculated using the corresponding BID price. Instead of the BID, the ASK is used. I think this is misleading. There was one time the account showed unrealized profit of about $400, and I decided to close the trade; and to my dismay, I ended up with a realized loss of about $200. Any comments?
