What would happen if trades were discontinuous? Like, place orders and they're processed once every hour? If some issues are worth x$ to your eyes, the company doesn't actually get or lose value by the minute, it's just that the public isn't aware of corporate facts yet, and as information becomes complete on the traders' side that they decide that issues are worth a bit less or a bit more for them. So if we traded only once per hour, wouldn't the stock exchange provide the same value to the economy, while leaning off a good part of the finance industry who rides on minute-to-microsecond trends?
