The original title is about execution latency in a Polymarket trading bot. Let me rewrite this for a mobile feed.
Original: Execution Latency in My Polymarket Trading Bot - Sub-Second Trade Execution System Design
Short summary
A developer shares lessons from building a Polymarket trading bot that has placed 11,717 trades, breaking down execution latency across four layers: signal generation (50-200ms), order signing (10-50ms), CLOB API submission (100-400ms), and on-chain confirmation (1-3s). The key insight is that on-chain confirmation on Polygon is an uncontrollable fixed cost, so the real challenge is structuring execution so unavoidable latency doesn't kill winning trades. Practical optimizations include pre-built order templates, persistent API connections, US East VPS hosting, 90th-percentile gas pricing, and a T-90 second cutoff before market resolution.
- •Execution latency on Polymarket is dominated by on-chain confirmation (1-3s on Polygon), not client-side processing
- •Key optimizations: pre-built order templates, persistent connections, US East VPS, limit orders at mid-price, T-90s resolution cutoff
- •Telegram alerts double as a latency monitoring system, tracking signal-to-confirmation time per trade
