> If this was such a great service why is IEX becoming so big? This is not an informed thesis. This is just an appeal reducible to the following statement: “A thing cannot be a good service if it has a large and organized opposition.” >HFT is a nightmare from a CSR view. Those companies provide no real value to society (not by any standard) and even worse: By hiring all those talented young people with degrees in various fields they actually hurt society. If your thesis is that HFT provides no benefits for society, please provide a substantive rebuttal against the claim that it improves liquidity and price discovery. HFT increases the availability of bids and asks in the orderbook by rapidly volunteering to be the trading counterparty in otherwise inefficient markets. By seeking the best price for its own strategies and making as many trades as possible with as little latency as possible, the increased liquidity is accompanied by improved price discovery. > Give those people real problems to work on, instead of wasting them on optimizing those HFT systems. Please define “real problem”, and please explain how the aforementioned benefits contributed by HFT are incompatible with this definition. Meanwhile keep in mind that the vast majority of companies, including those in tech, likely do not work on “real problems”, so next I’m going to ask why this is a meaningful criticism in the first place.
