I've been trading a bit over the last few years with custom software I've built for the cryptocurrency space.. mainly on Coinbase. With Coinbase I can get a level-3 data feed with sub-10ms latency (as long as my algo is running in AWS), and I can get execution times on the order or 20ms or so. Is there any way I can get similar results in the traditional finance world, or will I always be doomed to have my orders front-run by faster, better (physically co-located) algos? I'm thinking about dipping my toe in the traditional finance system with CME futures for Bitcoin (makes sense, right?). Is there a full orderbook data feed that has under say, 20ms of latency that can be purchased? Any brokers that can guarantee order placements under 50ms, or 100ms at most?
