When markets are closed, the bid/ask spreads will not be accurate because there’s no market open and no market being made. Now, in pre-market and post-market, sometimes, you’ll see the bid or ask go up differently from the previous days close or that day’s close to reflect activity in that pre- or post-market trading session. But at least there’s bonafide trading going on then (albeit much more thinly traded than the regular trading session). But when the market is closed and there’s no pre- or post-trading going on, the bid/ask prices you see mean nothing because they’re not fresh quotes from a market maker. Hope this helps. Thx.
