# Polymarket FastLoop Trader

Trade Polymarket's 5-minute crypto fast markets using real-time price signals. Default: BTC momentum from Binance. Works with ETH and SOL too.

> **Polymarket only.** All trades execute on Polymarket with real USDC. Use `--live` for real trades, dry-run is the default.

> **This is a template.** The default signal (Binance momentum) gets you started — remix it with your own signals, data sources, or strategy. The skill handles all the plumbing (market discovery, import, trade execution). Your agent provides the alpha.

> ⚠️ Fast markets carry Polymarket's 10% fee (`is_paid: true`). Factor this into your edge calculations.

> ⚠️ **Risk monitoring does not apply to sub-15-minute markets.** Simmer's stop-loss and take-profit monitors check positions every 15 minutes — which means they will never fire on 5m or 15m markets before resolution. Any risk settings you configure in the Simmer dashboard have no effect on these positions. Size accordingly and do not rely on automated stop-losses for fast market trades.

## How It Finds Markets

- Queries **Polymarket directly** (Gamma API) for live fast markets — doesn't depend on Simmer's market inventory
- Discovers new markets as they appear, every cycle
- Works with BTC, ETH, or SOL — just change the asset (`--set asset=ETH`) or ask your bot to look for whatever market you want
- Runs every 5 minutes to catch each trading window (or every 1 minute for mid-window opportunities)

**You don't need to wait for markets to show up in Simmer.** FastLoop finds them in real-time on Polymarket, then imports and trades them through Simmer.

## When to Use This Skill

Use this skill when the user wants to:
- Trade crypto sprint/fast markets (5-minute or 15-minute) on any supported asset
- Automate short-term crypto prediction trading
- Use CEX price momentum (or any custom signal) as a Polymarket signal
- Monitor sprint market positions

## Setup Flow

When user asks to install or configure this skill:

1. **Ask for Simmer API key**
   - Get from simmer.markets/dashboard → SDK tab
   - Store in environment as `SIMMER_API_KEY`

2. **Ask for wallet private key** (required for live trading)
   - This is the private key for their Polymarket wallet (the wallet that holds USDC)
   - Store in environment as `WALLET_PRIVATE_KEY`
   - The SDK uses this to sign orders client-side automatically — no manual signing needed

3. **Ask about settings** (or confirm defaults)
   - Asset: BTC, ETH, or SOL (default BTC)
   - Entry threshold: Min divergence to trade (default 5¢)
   - Max position: Amount per trade (default $5.00)
   - Window: 5m or 15m (default 5m)

4. **Set up cron or loop** (user drives scheduling — see "How to Run on a Loop")

## Quick Start

```bash
# Set your API key
export SIMMER_API_KEY="your-key-here"

# Dry run — see what would happen
python fastloop_trader.py

# Go live
python fastloop_trader.py --live

# Live + quiet (for cron/heartbeat loops)
python fastloop_trader.py --live --quiet

# Live + smart sizing (5% of balance per trade)
python fastloop_trader.py --live --smart-sizing --quiet
```

## How to Run on a Loop

The script runs **one cycle** — your bot drives the loop. Set up a cron job or heartbeat:

**Linux crontab** (local/VPS installs):
```
# Every 5 minutes (one per fast market window)
*/5 * * * * cd /path/to/skill && python fastloop_trader.py --live --quiet

# Every 1 minute (more aggressive, catches mid-window opportunities)
* * * * * cd /path/to/skill && python fastloop_trader.py --live --quiet
```

**OpenClaw native cron** (containerized or OpenClaw-managed setups):
```bash
openclaw cron add 
  --name "Fast Loop Trader" 
  --cron "*/5 * * * *" 
  --tz "UTC" 
  --session isolated 
  --message "Run fast loop trader: cd /path/to/skill && python fastloop_trader.py --live --quiet. Show the output summary." 
  --announce
```

**Via OpenClaw heartbeat:** Add to your HEARTBEAT.md:
```
Run: cd /path/to/fast market && python fastloop_trader.py --live --quiet
```

## Configuration

Configure via `config.json`, environment variables, or `--set`:

```bash
# Change entry threshold
python fastloop_trader.py --set entry_threshold=0.08

# Trade ETH instead of BTC
python fastloop_trader.py --set asset=ETH

# Multiple settings
python fastloop_trader.py --set min_momentum_pct=0.3 --set max_position=10
```

### Settings

| Setting | Default | Env Var | Description |
|---------|---------|---------|-------------|
| `entry_threshold` | 0.05 | `SIMMER_SPRINT_ENTRY` | Min price divergence from 50¢ to trigger |
| `min_momentum_pct` | 0.5 | `SIMMER_SPRINT_MOMENTUM` | Min BTC % move to trigger |
| `max_position` | 5.0 | `SIMMER_SPRINT_MAX_POSITION` | Max $ per trade |
| `signal_source` | binance | `SIMMER_SPRINT_SIGNAL` | Price feed (binance, coingecko) |
| `lookback_minutes` | 5 | `SIMMER_SPRINT_LOOKBACK` | Minutes of price history |
| `min_time_remaining` | 60 | `SIMMER_SPRINT_MIN_TIME` | Skip fast markets with less time left (seconds) |
| `asset` | BTC | `SIMMER_SPRINT_ASSET` | Asset to trade (BTC, ETH, SOL) |
| `window` | 5m | `SIMMER_SPRINT_WINDOW` | Market window duration (5m or 15m) |
| `volume_confidence` | true | `SIMMER_SPRINT_VOL_CONF` | Weight signal by Binance volume |

### Example config.json

```json
{
  "entry_threshold": 0.08,
  "min_momentum_pct": 0.3,
  "max_position": 10.0,
  "asset": "BTC",
  "window": "5m",
  "signal_source": "binance"
}
```

## CLI Options

```bash
python fastloop_trader.py                    # Dry run
python fastloop_trader.py --live             # Real trades
python fastloop_trader.py --live --quiet     # Silent except trades/errors
python fastloop_trader.py --smart-sizing     # Portfolio-based sizing
python fastloop_trader.py --positions        # Show open fast market positions
python fastloop_trader.py --config           # Show current config
python fastloop_trader.py --set KEY=VALUE    # Update config
```

## Signal Logic

Default signal (Binance momentum):

1. Fetch last 5 one-minute candles from Binance (`BTCUSDT`)
2. Calculate momentum: `(price_now - price_5min_ago) / price_5min_ago`
3. Compare momentum direction to current Polymarket odds
4. Trade when:
   - Momentum ≥ `min_momentum_pct` (default 0.5%)
   - Price diverges from 50¢ by ≥ `entry_threshold` (default 5¢)
   - Volume ratio > 0.5x average (filters out thin moves)

**Example:** BTC up 0.8% in last 5 min, but fast market YES price is only $0.52. The 3¢ divergence from the expected ~$0.55 → buy YES.

### Remix It: Plug In Your Own Signal

**This skill is a template.** The default Binance momentum signal is just a starting point. The skill handles all the boring parts (market discovery, import, order execution, budget tracking). You bring the signal.

Ideas for custom signals:
- **Multi-exchange spreads:** Compare prices across Binance, Kraken, Bitfinex — divergence between exchanges can predict CLOB direction
- **Sentiment:** Layer in Twitter/social signals — a viral tweet can move fast markets before the CLOB adjusts
- **Technical indicators:** RSI, VWAP, order flow analysis from your favorite data source
- **News:** Breaking news correlation — use your agent's reasoning to interpret headlines
- **On-chain data:** Whale movements, funding rates, liquidation levels

To customize, edit `get_momentum()` in `fastloop_trader.py` or add your own signal function. The rest of the skill (discovery, import, sizing, fee-aware EV check) stays the same.

## Source Tagging

All trades are tagged with `source: "sdk:fastloop"`. This means:
- Portfolio shows breakdown by strategy
- Other skills won't interfere with your fast market positions
- You can track fast market P&L separately

## Troubleshooting

**"No active fast markets found"**
- Fast markets may not be running (off-hours, weekends)
- Check Polymarket directly for active BTC fast markets

**"No fast markets with >60s remaining"**
- Current window is about to expire, next one isn't live yet
- Reduce `min_time_remaining` if you want to trade closer to expiry

**"Import failed: Rate limit exceeded"**
- Free tier: 10 imports/day. Pro: 50/day
- Fast market trading needs Pro for reasonable frequency

**"Failed to fetch price data"**
- Binance API may be down or rate limited
- Try `--set signal_source=coingecko` as fallback

**"Trade failed: no liquidity"**
- Fast market has thin book, try smaller position size

**"External wallet requires a pre-signed order"**
- `WALLET_PRIVATE_KEY` is not set in the environment
- The SDK signs orders automatically when this env var is present — no manual signing code needed
- Fix: `export WALLET_PRIVATE_KEY=0x<your-polymarket-wallet-private-key>`
- Do NOT attempt to sign orders manually or modify the skill code — the SDK handles it

**"Balance shows $0 but I have USDC on Polygon"**
- Polymarket uses **USDC.e** (bridged USDC, contract `0x2791Bca1f2de4661ED88A30C99A7a9449Aa84174`) — not native USDC
- If you bridged USDC to Polygon recently, you likely received native USDC
- Swap native USDC to USDC.e, then retry
