Letely, the price is going up but many of those offers may have been made a day ago or something.
Also, some people may be willing to take a little haircut to get the trade done fast. This is how price discovery works on an order book, spreads should get smaller as liquidity goes up
An offer that’s on the book is on the book. If the person who made it wants to take it down they can. If it’s still there you can take it.
Of course they do. Not all of them, but they do. Just like grocery stores to 10% off stuff they want gone. If someone needs to sell fast, the best incentive is a little discount.
