What is Polymarket Copytrading?
The Polymarket Copytrading skill is a powerful tool within the Openclaw Skills ecosystem designed to bridge the gap between retail traders and market whales. By leveraging the Simmer SDK, this skill automates the complex process of tracking, aggregating, and executing trades based on the real-time movements of successful prediction market participants. It effectively handles the technical plumbing of wallet fetching, conflict detection, and trade execution, allowing users to focus on selecting high-alpha strategies.
This skill goes beyond simple mirroring by implementing size-weighted aggregation and conviction scoring. When multiple followed wallets enter the same position, the skill recognizes the higher conviction and adjusts allocation accordingly. It also features robust safety mechanisms, such as filtering out stale or drifted markets, ensuring that users aren't entering trades that have already reached their logical conclusion or moved too far from the whale's entry price.
Polymarket Copytrading Use Cases
- Copytrade high-net-worth whale wallets on Polymarket to leverage their research and market influence.
- Paper trade using $SIM tokens to test copytrading strategies in a risk-free environment.
- Monitor specific trader addresses to receive real-time updates on their prediction market holdings.
- Perform portfolio rebalancing to ensure your personal holdings align with your selected top-tier traders.
- Identify high-conviction market signals by aggregating data across multiple expert wallets.
How Polymarket Copytrading Works
- The skill fetches current position data from all specified target wallets via the Simmer API.
- It performs size-weighted aggregation, giving more influence to wallets with larger positions.
- Conflict detection logic identifies if different whales hold opposing positions (YES vs NO) on the same market and skips those markets to avoid neutral hedging.
- A conviction score is assigned: positions held by two or more wallets receive 100% sizing, while single-wallet positions are scaled to 50%.
- Safety filters are applied to remove 'drifted' positions (moved >30% from entry) or 'stale' markets (price >90% or <10%).
- The script calculates the necessary trades to match target allocations based on the user's balance and 'Top N' settings.
- Trades are executed through the Simmer SDK, respecting all Polymarket constraints and user spending limits.
- A comprehensive report is generated, detailing trades executed, markets skipped, and current portfolio status.

Polymarket Copytrading Data Schema & Taxonomy
The skill organizes data based on wallet influence and market conviction. The following table outlines the auto-calculation for position concentration based on your balance:
| Account Balance | Default Top N Positions | Max USD Per Position |
|---|---|---|
| < $50 | Top 5 | Variable |
| $50 - $200 | Top 10 | Variable |
| $200 - $500 | Top 25 | Variable |
| $500+ | Top 50 | $50 (Default) |
Data is processed via the sdk:copytrading source and tracked within your Simmer portfolio metadata.
Polymarket Copytrading Advanced Features
