HFT doesn't really do anything for markets since they take very little risk, and that is the purpose of a market... the magic coil will kill your business anyway

I thought true HFT (not short-term momo, etc. where the intention is to actually take risk) had essentially died already, Virtu aside

True HFT is not in any sense dead, it's just matured so only those with deeper pockets can compete.
