What Is Latency Arbitrage?
Latency arbitrage exploits the fact that price updates propagate across exchanges at different speeds. When a large trade moves the price on Exchange A, there is a brief window (milliseconds to seconds) before the price updates on Exchange B. A latency arbitrageur who sees the move on A first can trade on B at the stale price before it adjusts, locking in a near-riskless profit.
How Latency Arbitrage Works
In crypto, latency arbitrage opportunities are larger and more frequent than in traditional markets because: crypto exchanges have less sophisticated matching engines, cross-exchange connectivity varies widely, and price discovery happens across dozens of fragmented venues. Strategies range from simple cross-exchange spot arbitrage to complex multi-leg trades involving futures and options across venues.
Why It Matters for Traders
While individual retail traders cannot compete in pure latency arbitrage (which requires co-located servers and custom networking), understanding it explains market behavior. Latency arbitrageurs provide a service: they align prices across exchanges, ensuring you get similar prices regardless of where you trade. Their activity is why price discrepancies between major exchanges are typically small and brief. Persistent price divergences between exchanges may signal exchange-specific issues (frozen withdrawals, solvency concerns).
