Quote from plan:
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?
Quote from def:
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).
