↓
You buy $100
Maximum trade size is automatically enforced.
Example:
Calculated copy size = $320
Maximum allowed = $100

The bot can copy trades across any supported Polymarket market, including:

Copy trading involves significant financial risk.
The bot attempts to replicate publicly visible trades but cannot guarantee identical execution prices or fills. Market conditions, liquidity, latency, and order book movement may produce different results from the tracked wallet.
Past performance of copied wallets does not guarantee future returns.
