> Nanosecond pricing updates might be a little more than anybody needs That may be the case, but the 'problem' is caused because market makers aren't legally allowed to offer better prices than they might otherwise desire. It doesn't seem prudent to layer flawed regulation on top of flawed regulation when there's a simpler solution. > Remember the market is ultimately about allocating capital between businesses and governments Equity markets have many purposes. Companies indeed raise money by issuing equity (IPOs and secondaries), and there are cases where governments participate for monetary purposes (BoJ & SNB's equity purchases). But markets also allow: * employees to sell equity compensation they've received whenever they want * retail investors to diversify their asset allocations * sovereign wealth funds, pension funds, endowments, and other real money sources return on their portfolios * for hedging financial risks * companies to return money to shareholders in the form of buy backs > for economic purposes it doesn't need to run any faster than they can All the previously mentioned functions happen all the time, and the marks (prices) generated from this activity helps inform many other economic functions. Everything from central bank policy to insurance pricing depends on well functioning markets. In light of this, why should we make things less efficient by slowing things down and driving the cost up?
