Prediction Market Copy Trading
Copy trading on Polymarket means automatically replicating a top trader's positions in real time. Merlin's Telegram bot tracks on-chain activity and mirrors trades to your wallet — free, with no minimum investment and no platform fees.
What Is Copy Trading?
Copy trading is a strategy where you automatically replicate the trades of another trader. On prediction markets like Polymarket, this means when a top trader buys shares in a market, the same trade is executed in your wallet.
Unlike traditional finance copy trading (e.g., eToro), prediction market copy trading operates on-chain. All trades are publicly verifiable on the Polygon blockchain, which means performance data is transparent and cannot be faked.
How Merlin Copy Trading Works
Merlin's Telegram bot connects to Polymarket's on-chain activity via WebSocket feeds. When a tracked trader executes a trade, Merlin detects it and submits the same order to your wallet within seconds.
- Browse the leaderboard — find traders ranked by P&L, return, and volume across 8 categories.
- Evaluate the trader — check Merlin Score (0-100), Return Rating (S/A/B/C/D), win rate, and trading history.
- Click "Copy Trade" — the Telegram bot opens pre-loaded with the trader's wallet address.
- Fund your wallet — deposit USDC to your Merlin wallet on Polygon.
- Trades are mirrored automatically — every buy and sell the trader makes is replicated in real time.
How to Choose a Trader
Not all profitable traders are good copy targets. Merlin provides proprietary metrics to help evaluate consistency and risk. See the Methodology page for full formulas.
Tip: Look for traders with consistent performance across multiple time periods (7d, 30d, all-time), not just a single period spike. Check the Insider Score to avoid traders with suspicious edge.
Risk Management
Copy trading does not eliminate risk. The trader you follow can lose money, and you will incur the same losses. Key principles:
- Diversify — copy 2-3 traders across different categories (politics, crypto, sports) to reduce correlation.
- Size appropriately — never allocate more than you can afford to lose. Start with a small amount to test.
- Monitor regularly — check your positions and the trader's recent performance. Cancel if the strategy no longer works.
- Understand the markets — prediction markets settle binary outcomes. A position can go to $0 if the event resolves against you.
Copy Trading vs Direct Trading
Both approaches have trade-offs. Copy trading suits users who want passive exposure to prediction markets without active research.
| Copy Trading | Direct Trading | |
|---|---|---|
| Time required | 5 min setup, then passive | Active research and monitoring |
| Knowledge needed | Evaluate trader metrics | Understand markets and probabilities |
| Control | Delegated to the trader | Full control over every trade |
| Risk | Correlated with one trader | Diversified by your own decisions |
| Best for | Beginners, passive users | Experienced traders |
