The market is still very much driven by humans; the computers just help out, to varying degrees. The idea that computers are trading unattended is a myth that I hope would die.

- cameronh90 7y agoThe pipeline for a given piece of research to get into production tends to be several months. Therefore, a small firm with only a few researchers might update between once and a few times a month, and a larger company it might be several times a week. It's rare to update the model more than once a day, since it'll normally be updated outside trading hours.
