Back in March of 2014, when Virtu had just released its first attempt at going public (soon to be followed by a second one now that everyone has apparently forgotten that HFTs are nothing but frontrunning, market-destabilizing predators), we wrote "The Is The One Financial Product Now Targeted By The HFT Swarm" in which we showed that with equities no longer a fertile ground to frontrun whale orders, what the algos were focusing their attention on was currencies. Earlier today, we got a glimpse of precisely how HFTs are now making a mockery of FX "price discovery" when completely independent of any newsflow, Canadian Dollar futures cratered on what is merely the latest of many flash crashes now coming to an FX market near you.
