Here's my question, which is more "philosophical": Why deploy HFT strategies at all? The primary (only?) advantage seems to be speed, which is basically a technological arms race and depends less on the sophistication of the strategy itself, meaning that whatever advantage you have for the moment will surely fade away, even in the short term.
So what are the pros, in terms of KPIs (e.g. ROI, sharpe etc.) vis-a-vis say "medium" frequency trading (e.g. intraday)? Would you consider your competitive advantage in your ability to _renew_ your strategies, rather than the strength of individual strategies?
