I recently came across an insightful article that broke down how API latency across top exchanges directly impacts trading efficiency - and honestly, it lined up perfectly with my own experience.
The article compared real-world API latency across popular platforms, and the results were eye-opening:
🟢 Gatе.іо and WhiteBIT — 5 ms. That’s HFT-level speed, where milliseconds = money.
🟡 KuCoin — 15 ms, acceptable, but in arbitrage that already feels like “yesterday’s speed.”
🟠 Bybit — under 10 ms, solid for options strategies and delta hedging.
💡 API isn’t just about convenience. It’s a critical asset if you want to trade fast, aggressively, and with mathematical edge. Even a 10–20 ms gap can decide who gets the fill — you or the next bot in line.
