Copy Trading
Automatically follow top traders' positions
Overview
Copy trading lets you automatically mirror the trades of top-performing wallets. When a trader you follow places a trade, Vezta detects it and executes the same trade on your behalf -- proportionally sized to your settings. This is one of Vezta's most powerful Pro features, turning the leaderboard into an actionable trading tool.
Copy trading works on Polymarket markets, where wallet activity is publicly observable on-chain. Kalshi-via-DFlow trades are anonymized at the on-chain level (you only see the DFlow program address), so copy trading does not work for Kalshi markets.
How It Works
Find a trader to follow
Browse the Leaderboard or Wallet Tracker to identify high-performing Polymarket traders. Look at their ROI, win rate, and trade history.
Configure your copy settings
Set your allocation amount, sizing strategy, risk controls, and category filters. These determine how much capital you commit and what trades get mirrored.
Trades execute automatically
When the target wallet places a trade, Vezta detects it via on-chain Polymarket monitoring (within seconds) and mirrors the position for you. You receive a notification on the user:copy-trade WebSocket channel for each event.
Monitor and adjust
Track your copy trading performance in the Copy Trade dashboard. Pause, adjust settings, or unsubscribe at any time.
Configuration Options
When setting up a copy trade subscription, you can customize:
Sizing Strategy
- Fixed amount -- every copied trade uses the same dollar amount (e.g., $50 per trade)
- Percentage of target -- size your trade as a percentage of the target trader's position
Risk Controls
| Setting | Description |
|---|---|
| Max per trade | Maximum dollar amount for any single copied trade |
| Max position size | Cap on total exposure per market |
| Daily trade cap | Maximum number of copied trades per day |
| Daily loss limit | Pauses copying if your daily loss exceeds this threshold |
| Slippage tolerance | Skips a trade if the price has moved too far since detection |
Filters
- Category filter -- only copy trades in selected categories (Politics, Crypto, Sports, etc.)
- Probability range -- only copy trades within a certain probability window (e.g., 20-80%)
- Min liquidity -- skip markets with low liquidity
Automated Exits
- Mirror exit -- automatically sell when the target trader exits their position
- Take profit -- close your position when profit reaches a set percentage
- Stop loss -- close your position when loss reaches a set percentage
Detection Flow
Polymarket trades are detected via the backend's trade-sync pipeline (every few minutes for the hot-set, plus a global recent-trades poller every 30 seconds for top-volume markets). When a tracked wallet shows up in fresh trades, the copy-trade processor enqueues a mirror order against the same market and side.
Managing Subscriptions
The Copy Trade page (/copy) shows all your active subscriptions with real-time stats:
- Number of trades copied
- Total PnL from copied trades
- Win rate
- Last trade timestamp
You can pause a subscription to temporarily stop copying without losing your configuration, edit settings at any time, or unsubscribe to permanently stop following a trader.
Copy trading carries risk. Past performance does not guarantee future results. Always use risk controls and monitor your subscriptions regularly.
