Markets/exchanges often use call auctions, where market participants place orders to buy/sell and these are batched together and matched at predetermined time intervals. This can be instead of or in addition to continuous real-time trading. For example, the NYSE has opening and closing auctions in addition to real-time trading during the day.

Auctions provide better liquidity and lower transaction costs. The main disadvantage is that trades do not execute right away, but instead wait until the next auction. Though this disadvantage also has some benefits, in that it lessens or evens out the reward for very fast trading on news updates or high-frequency trading.

It has been proposed that running auctions every second would provide significant advantages without significant disadvantage - few non-HFT traders would even notice the difference if trades are executed every second instead of continuously. On Manifold, most markets rarely see multiple trades per second, so you could also consider time intervals of every say 10 seconds, minute, or whatever - the longer the interval the better the liquidity but the longer market participants have to wait for trades and price updates.

Resolution

This market resolves YES if at any point in 2023, Manifold implements any auction-based trading mechanism. It can be in addition to or instead of continuous trading. If it is implemented and then removed, that still counts as YES.
