I don&#x27;t understand why stock markets function this way. Why don&#x27;t they work like a Diplomacy game, in turns?<p>Everyone puts their instructions in, then the turn &#x27;executes&#x27; and an algorithm (known to all parties) resolves the actions. Run one turn every second. If you want to buy all 20k shares on offer and nobody else is making the same bid, you get them. Seems reasonably straightforward - what am I missing?
