> mean/med/p99/p999/p9999/max over day, minute, second, 10ms So basically you’re taking 18 measurements and checking if they’re <10ms? Is that your time budget to make a trading decision, or is that also counting the trip to the exchange? How frequently are these measurements taken, and how do HFT folks handle breaches of this quota? Not in finance, but I operate a high-load, low latency service and I’ve always been curious about how y’all think about latency.
