Building a Polymarket Trading Bot: Architecture, Execution, and Risk Management

Short summary

Developer built a real-time trading bot for Polymarket crypto markets monitoring BTC, ETH, SOL, and XRP with a five-component architecture (data feed, signal engine, risk manager, order engine, API layer). System prioritizes risk management—position limits, exposure caps, automatic halts—over signal complexity. Key insight: data quality and execution speed matter more than sophisticated trading signals.

• •Five-component architecture isolates market data, signal generation, risk management, and execution for independent failure handling
• •Risk controls are the foundation: position limits, portfolio exposure monitoring, and automatic trading suspension prevent cascading failures
• •Data accuracy and execution latency trump signal sophistication; maker rebates provide consistent returns independent of directional accuracy
