>But what is the social benefit of the stock markets being synced to the state of the economy at the micro-second / nano-second time scale ? It's cheaper than people doing it, and the lower the latency, the faster a trader can move his position to match changes in the market. What is the social benefit of Twitter loading in 100ms instead of 150ms? Why is latency important for peoples' stupid mobile apps, but not important for financial transactions? >Nothing in the real economy changes that fast. Sure, but you don't want to have to wait for an earnings report to sell your shares when you want to buy a house or something. You want people to always be trading your stock so it's easy to buy and sell. Similarly, when a big pension fund buys or sells a lot of your stock at once you want "people" trading to reduce volatility. |
