I think the next few improvements require a major refactor so I'mma call this experiment finalized till it's a bottleneck. It was a fun project and I learned a lot, hope y'all got some value from it too! 🫡 Onto next project -> porting tungstenite to glommio (I think lol)

Sometimes I get blindsided by the competitive, structural advantages that TradFi has and want that in Crypto too However, this "tech inefficiency" leaves a massive edge on the table. For example, building out kernel bypass on AWS is +EV only *because* it's not implicit

@bayeslord New algo (past month or so I think?) feels like it intentionally broke up naturally-formed clusters to push generic mainstream content for ad rev

Also if you haven't checked out @MarkBestForex 's blog by now, you're missing out! He's got some great resources, especially for the HFT Rust crowd

I've said it before & I still truly believe that Crypto is a quant gold rush The tech & regulation frictions mixed with a high retail / inst ratio make it a perfect environment to compete in at any level

@KlondikeFX It's just so beautifully well timed, time to do a deep dive into the data but here's what the aggregates look like Very happy with the results as everything remained stable and there were no abnormal data point jumps

@BruHFT_quant @quant_arb Yes, we’re collocated at NYSE and CBOE. Waiting on A100 and H100s on order. Next phase is deploying Xilinx hardware and implementing a MW backhaul. Expected outcome is sub 5ns tick to trade
