Latency matters on Polygon

Use endpoints with consistent low latency and watch for endpoint throttling. Measure, rotate if needed, and keep filters balanced for recall vs noise.

Quick checklist

• Measure WSS median/variance; keep < 150 ms when possible
• Enable backpressure handling
• Prefer private bundles; monitor inclusion
• Strict slippage/gas/session caps
