I cannot be less honest and straight-forward about this as it gets more and more serious. IB quote is like a joke. I don't know why. There is fake bid/ask/size all the time. When you try to hit them, there is no execution. This could be either a serious irregular problem such as delays/missed-update in their systems, or the rumor which speculate that there are some sort of middle-man scheme manipulating the customers is true. I don't know. You tell me! me and friends are tired of these. It does not justify the commissions paid to you! no now!
You gave them a negative review on Nov. 9, 2002 and posted numerous negative posts about them over the months. They must be doing something right for you to keep using them. Hurry up and change to another broker and you'll be happy! Good Luck!
I've been using IB for quite a while now. I'm very pleased. But if I were you and I was that dissatisfied, I'd switch. But either switch or quit the complaining. OldTrader
There certainly is no manipulation or scheme going on. However, I have recently noticed some quote delays any time the market gets a little busy (not a connection issue). This may be what you are experiencing.
