It's interesting you posted this, then about a day afterwards Luminex was announced [1] [2]. I'm not familiar with the term of art "latency stingray", and it doesn't turn up in a Google, can you please point me to a page about it? I'm confused about your assertion "a lot of players high up..."; GS is quite high up there, and they're very active in HFT, as are many others, so that seems at odds with your assertion that powerful players are "tired of HFTs" (unless they are playing only to essentially defend their more strategic interests). Any more powerful than them, and I'm thinking executive political participants, but I'm hard-pressed to think of any of them who could actually put something actionable into place would care about HFTs. Unless the volatility induced by HFTs during certain market scenarios is presenting a problematic obstacle for achieving specific nation-state strategic goals, I can't see how national-level political actors would involve themselves with clamping down on HFT activity? Anyways, fascinating food for thought, thanks for bringing this up.
