Copy Trading (Whale / Smart Money Replication)

How It Works Polymarket's on-chain order book makes all trades publicly observable. This strategy identifies wallets with strong historical performance (high win rate, large position sizes, or consistent profitability) and automatically mirrors their trades in real time. When a target wallet places a trade, the copy-trading bot executes the same position at similar sizing.

Entry/Exit Conditions Entry is triggered when a monitored wallet executes a qualifying trade — typically filtered by minimum size, market type, or wallet performance metrics. Exit mirrors the target wallet's exit, or may be triggered independently by stop-loss rules. Some implementations may lead-copy (anticipate) rather than lag-copy (replicate after confirmation).

Verified Results No verified results are disclosed. Copy trading is referenced in the MstKail/polymarket-trading-bot-services-polyedge365 repository description, which reads as a keyword-stuffed promotional listing (104 stars, 251 forks — suspicious ratio suggesting artificial inflation). This repo is likely low-quality or promotional.

Implementation Notes The PMXT unified API (pmxt-dev/pmxt) could simplify implementation by providing standardized market data access. On-chain transparency is the key enabler — unlike traditional finance, Polymarket's Polygon-based settlement makes all wallet activity auditable. Effective copy trading requires fast mempool monitoring or subgraph indexing to detect trades before significant slippage occurs.

Risks Survivorship bias is severe — past performance of a wallet may not persist. Profitable wallets may be trading on private information not available to copiers. Lag between target trade and copy execution can result in worse fill prices. Large copy-trading volumes can move markets against the strategy. The MstKail repo specifically appears to be a promotional or scam listing and should not be used as an implementation reference.
