Why Copy Whales?
Whales — traders with $10,000+ positions — typically have better information and analysis than retail traders. Their large commitments indicate high conviction. Following their trades gives you exposure to institutional-quality research.
PredictEngine's whale tracker monitors all large Polymarket trades in real-time. When a whale opens a significant position, the copy bot mirrors it proportionally in your wallet.
How Whale Detection Works
The system monitors Polygon blockchain transactions for large Polymarket trades. You configure your minimum whale threshold (e.g., $5,000+ trades). When a qualifying trade is detected, the bot receives an alert.
Smart filtering: the bot distinguishes between new position opens (strong signal) and position adjustments or sells (different signal). Focus on new large buys for the strongest alpha.
Bot Configuration
Set your whale threshold, position sizing (e.g., 2% of the whale's trade size), maximum exposure per market, and market filters. You can focus on specific categories like crypto-only or sports-only whale trades.
Enable multi-whale mode to track multiple large wallets. When 2+ whales independently enter the same position, the signal strength increases dramatically.
Tracking and Optimizing
Monitor your whale copy performance: win rate, average P&L per copied trade, and comparison to the whales' actual returns. Execution delay causes some tracking error.
Periodically review which whales are profitable to copy and which are not. Remove underperformers and add new top wallets from the leaderboard.

Frequently Asked Questions
How fast does the bot detect whale trades?
PredictEngine detects on-chain whale trades within seconds and executes your copy trade immediately.
What is a good whale threshold?
Start with $5,000+. This filters out noise while capturing meaningful informed trades. Adjust based on your results.
Can whales see that I am copying them?
No. Your trades are independent on-chain transactions. Whales cannot see who is copying their positions.
What if multiple whales disagree?
Only copy when you see consensus. If whales are split on a market, it is best to stay out and wait for clearer signals.
