Bid Price: The maximum price a buyer is willing to pay for a security. (You can say it’s the date they’re asking for, but they only ask when they are looking to buy!)
-
Ask Price: The minimum price a seller is willing to accept for a security. (It’s like the seller who won’t go lower than their asking price even if you offer them a sweet deal!)

If the NBBO for a particular stock is $10 (Bid) and $10.05 (Ask), this means you can sell your shares for $10 or buy them for $10.05, depending on which side you are on. If you are buying, note that you might not find it at that price because the world of stock trading is swifter than a cheetah on roller skates!
