Live Trading Setup (Optional)

For live trading, you'll need Polymarket API credentials:

Environment Variables

Create a

.env

file or set these environment variables:

# Polymarket CLOB API (for live trading)
POLYMARKET_API_KEY=your_api_key
POLYMARKET_SECRET=your_secret
POLYMARKET_PASSPHRASE=your_passphrase

# Alternative: Private key method
POLY_PK=your_private_key_hex
POLY_FUNDER=your_funder_address

Getting API Keys

1. Sign up at polymarket.com
2. Complete KYC verification
3. Deposit $1,000+ for CLOB API access
4. Generate API keys in account settings
5. Fund your account with USDC

Note: Paper trading works without any setup. API keys are only needed for live order placement.

• Medium Risk: Time decay, book imbalance
• High Risk: Momentum, latency arbitrage

Recommended Approach

1. Start with paper trading on all tools
2. Begin with low-risk NegRisk arbitrage
3. Scale gradually as you understand each strategy
4. Never risk more than 5% of capital per trade
5. Diversify across multiple strategies

Data Sources

• Market Data: Polymarket Gamma API (real-time, rate-limited)
• Order Books: Polymarket CLOB API (real-time pricing)
• BTC Price: Hyperliquid API (1-minute candles, no rate limit)
• Volume Data: Historical and real-time Polymarket feeds

All tools handle rate limits automatically and include retry logic.

Troubleshooting

Common Issues

"No markets found"

• Check internet connection
• Verify Polymarket APIs are accessible
• Try again in a few minutes (temporary API issues)

"Rate limited"

• Tools automatically handle rate limits
• Wait for retry or reduce concurrent requests
• Consider using --no-books flag to reduce API calls

"No signals generated"

• Markets may not have optimal conditions
• Try different time periods or strategies
• Check if markets are active (weekends have lower volume)

"Tool timeout"

• Network connectivity issues
• Large universe scan can take 60+ seconds
• Use Ctrl+C to interrupt and retry

Debug Mode

Add debugging to any tool:

DEBUG=1 node negrisk_scanner.cjs scan

Legal & Disclaimer

• Not financial advice. These are educational tools.
• Paper trading recommended until you understand each strategy.
• Market risk exists. Prediction markets can be volatile.
• API dependencies. Polymarket could change/restrict APIs.
• Competition increases. As more people use these tools, edges may decrease.

Start small. Test thoroughly. Scale gradually.

Felix Bottom Line

Most prediction market traders lose money because they trade emotions, not math. This suite finds mathematical edges that exist before human psychology kicks in.

It won't make you rich overnight. It will find 5-15 systematic opportunities per day that institutional traders are already exploiting.

The question isn't whether these edges exist—it's whether you'll act on them before they disappear.

$19. Six tools. One unfair advantage.
