Polymarket FastLoop Trader

Trade Polymarket's 5-minute BTC fast markets using real-time price momentum from Binance.

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

How it works: Every cycle, the script finds the current live BTC fast market, checks BTC price momentum on Binance, and trades if momentum diverges from market odds.

This is a template. The default signal (Binance momentum) gets you started. Your agent's reasoning is the edge — layer on sentiment analysis, multi-exchange spreads, news feeds, or custom signals to improve it.

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

When to Use This Skill

Use this skill when the user wants to:

• Trade BTC sprint/fast markets (5-minute or 15-minute)
• Automate short-term crypto prediction trading
• Use CEX price momentum 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 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)

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

Quick Start

# 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:

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

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:

# 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

Example config.json

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

CLI Options

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.

Customizing Your Signal

The default momentum signal is a starting point. To add your own edge:

• Multi-exchange: 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
• Technical indicators: RSI, VWAP, order flow analysis
• News: Breaking news correlation — use your agent's reasoning to interpret headlines

The skill handles all the Simmer plumbing (discovery, import, trade execution). Your agent provides the alpha.

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
