Is everybody just getting used to IB's problems, or was I the only one that was having trouble yesterday? I haven't seen any other posts on the subject, but I was getting wacky quotes on Best_ECN all afternoon yesterday. Trades and executions seemed OK (I didn't use best ECN), but the quotes were way off. It makes me a little nevous. Did anyone else have the same problem? I did use Best Execution for the first time (I had been a little afraid of it) because of this problem. It worked fine and actually executed against ECNs every time I used it. I am considering using it as my main execution method on high volume big cap stocks. Does anyone have any warning or advise about this? Thanks for the input. PS I would like to thank everyone who gave me input on my new computer. I didn't want to bring the thread back to the front page, but I really appreciated the advice.
