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.

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

# 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):

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:

# 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

{
  "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.

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

• 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
