The bot currently uses the Polymarket Data API to monitor trader activity and detect new positions. The monitoring system polls trader positions at configurable intervals (default: 1 second) to ensure timely trade detection and execution.
🚀 Version 2 Available: An advanced version with RTDS (Real-Time Data Stream) monitoring is now available as a private repository. Version 2 features the fastest trade detection method with near-instantaneous trade replication, lower latency, and reduced API load. Copy trading works excellently in the advanced version.
I've also developed a monitoring bot for Polymarket built with Rust - it's a useful tool for tracking and analyzing market activity.
