IB bid/ask a ?

Sometimes I get a "?" in the place of bid/ask, especially if I have not traded the stock before.

I tried calling IB, they had no idea. Anyone here have any advice?

 

could be a few things. if the contract is expired (futures for example), if the market is closed and there is no updated of the bid/ask, if you exceeded the number of quote lines (30 but the number will increase dependent on commission levels).

 

Tx for response. No, it's stocks not futures, and it happens when market is open. I only watch around 10 names so don't exceed that either ....

However, I do watch around 100 stocks (the max) on QT with the IB feed. Could that be it?

 

yes, that's probably it as you're polling more than 100. (i was wrong about the 30 limit it's 100)

 

no last, no volume on QQQQ today

 

around 6500 stock for short today vs 8500 on average

 

not just Qs, but others as well.
