Copy Trading: Following Other Wallets

Follow and auto-replicate whale wallet trades

Copy trading automatically replicates trades from wallets you choose to follow. When the followed wallet opens a position, Predite opens a proportional position in your account. When they close, you close. It's a hands-off way to piggy-back on traders whose performance you trust.

## How to Set Up Copy Trading

Open **Dashboard → Copy Trading → New Copy**.

Configure:

- **Follow wallet.** The Polymarket wallet address you want to copy. You can find addresses in the Whale Tracker, Traders page, or just paste one you've identified yourself.

  • •**Copy percentage.** What fraction of their position size you replicate. 10% means if they buy $1000, you buy $100. Range: 1% to 100%.
  • •**Max size per trade ($).** Hard cap on any single copied trade. Even if their trade × your copy% would be larger, you cap at this number.
  • •**Min size per trade ($).** Skip trades below this size. Useful for filtering out tiny exploratory positions.
  • •**Categories.** Filter to specific market types (only copy their politics trades, not their crypto).
  • •**Mode.** Paper (simulate) or Live (execute via CLOB API).
  • •**Direction filter.** Copy both YES and NO trades, or only one direction.

After saving, the copy is active. Every time the followed wallet places a trade matching your filters, your account places a proportional one.

## How Trades Are Detected

Predite watches the Polymarket blockchain in real-time. When a trade settles on-chain from a followed wallet, our indexer:

1. Detects the new transaction 2. Decodes the trade (market, direction, size) 3. Matches it against active Copy configs 4. For each matching config, calculates your size (their size × copy%, capped at max size) 5. Submits the trade via your CLOB API credentials (Live) or simulates (Paper)

Detection-to-execution typically takes 30-90 seconds. If their move is very fast and the market moves significantly in that window, your fill price may differ from theirs.

## Choosing Wallets to Copy

The Whale Tracker and Traders page rank wallets by performance. When evaluating a wallet to copy:

- **Win rate.** What % of their resolved positions were profitable? Look for 55%+ consistently.

  • •**Average position size.** Big positions = high conviction trades. Tiny positions = exploratory.
  • •**Trade frequency.** Very high frequency (50+ trades/day) may be hard to mirror cost-effectively.
  • •**Win/loss size ratio.** Average winner $1500, average loser $400 = great. Reverse = bad.
  • •**Category specialization.** Some wallets are amazing at politics but mediocre at crypto. Use the category filter accordingly.
  • •**Drawdown history.** Look at their P&L curve. Long flat or down periods? They might be in one of those when you start copying.

## Sizing Across Multiple Copies

If you're copying 3 wallets each at 20% copy%, that's 60% total exposure to their decisions. That might be too concentrated. A reasonable rule:

- Sum of copy % across all wallets ≤ 100% (total exposure not exceeding your full bankroll)

  • •Per-wallet copy % ≤ 30% (no single wallet can blow you up)
  • •Max size per trade should be your own per-trade cap, not 1/Nth of their cap

## Stopping a Copy

Click the copy in the Copy Trading page → "Pause" stops new trades but keeps open positions. "Stop" cancels the copy entirely. Already-filled positions stay in your portfolio (close them manually if desired).

## Trade History and P&L

The Copy Trading page shows per-wallet stats:

- Total trades copied

  • •Average copy delay (seconds from their fill to yours)
  • •Average price slippage (your fill price − their fill price)
  • •Total P&L from this copy
  • •Win rate on resolved trades

If your copy P&L is significantly worse than the original wallet's P&L (>30pp gap), the delay + slippage is probably eating your edge. Consider lowering copy% or stopping the copy.

## Risks of Copy Trading

- **Past performance ≠ future.** A wallet that ran hot for 6 months may regress to the mean. Don't assume their edge persists.

  • •**Slippage erodes the edge.** Their fill at $0.40, your fill at $0.42 = you're starting 2pp worse on every trade.
  • •**They may stop trading.** No new trades = no copies. Check periodically that the wallet is active.
  • •**Resolution surprises.** They may know something about a specific market that the AI doesn't. If you're copying without your own view, you can't tell which trades are skill vs. luck.
  • •**They may dump on you.** If they close before your sell triggers, you might exit at a worse price.
