Author	Topic: QQQQ bid/ask "stuck" (11 messages, Page 1 of 1)
nsolot -DTN Guru- Posts: 273 Joined: Sep 4, 2004	Posted: Sep 12, 2006 10:04 AM Msg. 1 of 11 Three times this morning (twice on the bid and once on the ask) the quotes have been "stuck". I'm pretty sure the underlying problem is with an exchnage (AMEX), but it sure would be slick if IQ or the underlying provider could build in logic to provide a "more accurate quote"

I have been watching the bid/ask change for about 5 minutes since your post and haven't seen the problem occur again. If we can determine how you solved the problem, we can possibly determine the initial cause. Thank you Paul

If you could send me your user id in a private message I can place a customer suggestion in our system for your above mentioned idea. Edited by DTN_Tim Walter on Sep 12, 2006 at 10:23 AM
DTN_Jay_Froscheiser -VP, Product Operations- Posts: 1746 Joined: May 3, 2004 DTN IQFeed/DTN.IQ/DTN NxCore	Posted: Sep 12, 2006 10:25 AM Msg. 6 of 11 looks like there is an AMEX quote that has been stuck with 100000 shares for 50+ minutes (since 10:32:22) . It is no longer the best Ask, so now the BBO is going to not look "stuck". If the best ask heads back above 39.29 it may effect it again. We will have to see what is going on with that quote as it obviously is stale. Jay Froscheiser DTN - Trading Markets

It is at 39.25 so it too may present an issue if the bid reaches that level. Hopefully our market data group will be able to get in touch with the exchange/MMID to figure out what is going on.

What I suggest, is when the bid/ask gets crossed up, to insert some logic to look at other quote sources. Regional bid/ask from CINN, ARCX and NMS are accurate. AMEX is messing up the Level 1 quotes.
