# Simmer Copytrading
Mirror positions from successful Polymarket traders using the Simmer SDK.
## When to Use This Skill
Use this skill when the user wants to:
- Copytrade whale wallets on Polymarket
- Check what positions a wallet holds
- Follow specific trader addresses
- Check their copytrading positions
## Quick Commands
```bash
# Check account balance and positions
python scripts/status.py
# Detailed position list
python scripts/status.py --positions
```
**API Reference:**
- Base URL: `https://api.simmer.markets`
- Auth: `Authorization: Bearer $SIMMER_API_KEY`
- Portfolio: `GET /api/sdk/portfolio`
- Positions: `GET /api/sdk/positions`
## Finding Whale Wallets
- **[predicting.top](https://predicting.top)** — Leaderboard of top Polymarket traders with wallet addresses
- **[alphawhale.trade](https://alphawhale.trade)** — Tools for copying and tracking top performers
- **Polymarket Leaderboard** — Official rankings (requires account)
## Quick Start (Ad-Hoc Usage)
**User provides wallet(s) directly in chat:**
```
User: "Copytrade this wallet: 0x1234...abcd"
User: "What positions does 0x5678...efgh have?"
User: "Follow these whales: 0xaaa..., 0xbbb..."
```
→ Run with `--wallets` flag:
```bash
python copytrading_trader.py --wallets 0x1234...abcd
python copytrading_trader.py --wallets 0xaaa...,0xbbb... --dry-run
```
This is the simplest way - no setup needed, just pass wallets directly.
## Persistent Setup (Optional)
For automated recurring scans, wallets can be saved in environment:
| Setting | Environment Variable | Default |
|---------|---------------------|---------|
| Target wallets | `SIMMER_COPYTRADING_WALLETS` | (none) |
| Top N positions | `SIMMER_COPYTRADING_TOP_N` | auto |
| Max per position | `SIMMER_COPYTRADING_MAX_USD` | 50 |
| Max trades/run | `SIMMER_COPYTRADING_MAX_TRADES` | 10 |
**Top N auto-calculation (when not specified):**
- Balance < $50: Top 5 positions
- Balance $50-200: Top 10 positions
- Balance $200-500: Top 25 positions
- Balance $500+: Top 50 positions
**Polymarket Constraints:**
- Minimum 5 shares per order
- SDK enforces $1.00 minimum position value (filters dust positions)
> ⚠️ **Start Conservative:** Begin with small amounts (`--max-usd 5-10`) and `--dry-run` to understand how the skill behaves before scaling up.
## How It Works
Each cycle the script:
1. Fetches positions from all target wallets via Simmer API
2. Combines using size-weighted aggregation (larger wallets = more influence)
3. Detects conflicts (one wallet long YES, another long NO) and skips those markets
4. Applies Top-N filtering to concentrate on highest-conviction positions
5. Auto-imports missing markets from Polymarket
6. Calculates rebalance trades to match target allocations
7. Executes trades via Simmer SDK (respects spending limits)
8. Reports results back to user
## Running the Skill
**Run a scan:**
```bash
python copytrading_trader.py
```
**Dry run (no actual trades):**
```bash
python copytrading_trader.py --dry-run
```
**Check positions only:**
```bash
python copytrading_trader.py --positions
```
**View current config:**
```bash
python copytrading_trader.py --config
```
**Override wallets for one run:**
```bash
python copytrading_trader.py --wallets 0x123...,0x456...
```
**Full rebalance mode (includes sells):**
```bash
python copytrading_trader.py --rebalance
```
**Sell when whales exit positions:**
```bash
python copytrading_trader.py --whale-exits
```
## Reporting Results
After each run, message the user with:
- Current configuration (wallets, Top N, max position)
- Number of wallets fetched and total positions found
- Markets skipped due to conflicts
- Trades executed (or skipped with reason)
- Current portfolio positions
Example output to share:
```
🐋 Copytrading Scan Complete
Configuration:
• Following 2 wallets
• Top 10 positions, max $50 each
• Balance: $250.00 USDC
Fetched positions:
• 0x1234...abcd: 15 positions
• 0x5678...efgh: 22 positions
• Combined: 28 unique markets
• Conflicts skipped: 2
Top 10 by allocation:
1. "Will BTC hit $100k?" - 18.5% → BUY YES
2. "Trump pardons X?" - 12.3% → BUY NO
3. "Fed rate cut Jan?" - 9.8% → Already held
...
Trades executed: 4 buys ($180 total)
• Bought 45 YES shares on "Will BTC hit $100k?" @ $0.82
• Bought 120 NO shares on "Trump pardons X?" @ $0.15
...
Next scan in 4 hours.

## Example Conversations
**User: "Copytrade 0x1234...abcd"**
→ Run: `python copytrading_trader.py --wallets 0x1234...abcd`
→ Report what positions that wallet has and what trades would execute
**User: "What is 0x5678...efgh holding?"**
→ Run: `python copytrading_trader.py --wallets 0x5678...efgh --dry-run`
→ Show their positions without trading
**User: "Follow these wallets: 0xaaa..., 0xbbb..., 0xccc..."**
→ Run: `python copytrading_trader.py --wallets 0xaaa...,0xbbb...,0xccc...`
→ Aggregate positions across all wallets, report results
**User: "Copytrade this whale but only top 5 positions"**
→ Run: `python copytrading_trader.py --wallets 0x... --top-n 5`
**User: "How are my positions doing?"**
→ Run: `python copytrading_trader.py --positions`
→ Show current Polymarket positions with P&L
**User: "Show copytrading config"**
→ Run: `python copytrading_trader.py --config`
→ Display current settings
**User: "Sell positions that whales have exited"**
→ Run: `python copytrading_trader.py --whale-exits`
→ Compares your positions to whales, sells any they've closed
**User: "Do a full rebalance to match the whales"**
→ Run: `python copytrading_trader.py --rebalance`
→ Includes both buys AND sells to match whale allocations
## Finding Good Wallets to Follow
Common approaches:
1. **Leaderboard tracking**: Check Polymarket leaderboards for consistent performers
2. **Whale watchers**: Follow known profitable traders on social media
3. **Specific strategies**: Follow wallets known for weather, politics, or crypto trades
The skill works best when:
- Following 2-5 wallets for diversification
- Wallets have similar conviction (don't mix degen with conservative)
- Wallets trade markets available on Polymarket
## Troubleshooting
**"Order too small" / "below minimum (5)"**
- Polymarket requires minimum 5 shares per order
- Increase `--max-usd` or reduce `--top-n` to concentrate into fewer positions
**"No wallets specified"**
- Provide wallet addresses in your message, e.g., "copytrade 0x1234..."
- Or set SIMMER_COPYTRADING_WALLETS environment variable for recurring scans
**"Agent has no USDC balance"**
- Need USDC in your Polymarket wallet
- Check wallet is linked at simmer.markets/dashboard
**"Conflict skipped"**
- Wallets disagree on this market (one long YES, other long NO)
- Markets with net position < 10% are skipped
**"Insufficient balance"**
- Not enough USDC for all trades
- Reduce SIMMER_COPYTRADING_TOP_N or SIMMER_COPYTRADING_MAX_USD
**"Market could not be imported"**
- Some markets may not be importable (resolved, private, etc.)
- These are skipped automatically
