Polymarket AutoTrader

Auto-trade BTC, ETH, SOL, XRP on Polymarket price prediction markets at 5-minute and 15-minute intervals using RSI, MACD, and EMA signals.

Automatically trades BTC, ETH, SOL, and XRP price prediction markets on Polymarket using short-term technical analysis signals.

How It Works

1. Signal Generation — Fetches OHLCV candles from Binance (public API, no key required) for each asset on the selected timeframe (5m or 15m). Computes RSI(14), MACD(12/26), and EMA(9/21) crossover.

2. Market Discovery — Queries the Polymarket Gamma API to find active, unclosed price prediction markets for the relevant asset expiring soon.

3. Order Placement — If signal confidence ≥ MIN_CONFIDENCE (default 60%), places a limit order on the soonest-expiring market:

   • BUY signal → buy YES tokens
   • SELL signal → buy NO tokens

4. Billing — Each cycle deducts 0.001 USDT via SkillPay before executing. If balance is insufficient, a top-up link is returned.

5. Scheduler — Runs automatically every 5 or 15 minutes (set via TRADE_TIMEFRAME).

Strategy Details

5-Minute Timeframe

Risk Warning

⚠️ Polymarket prediction markets are binary (YES/NO) and highly volatile. Past signal performance does not guarantee future results. Always start with DRY_RUN=true and small position sizes. Never risk capital you cannot afford to lose.

Usage (via Claude Code)

When this skill is active, you can ask Claude to:

• "Run the Polymarket AutoTrader for BTC and ETH on the 15m timeframe"
• "Show me the current signals for all assets"
• "Start the trader in dry-run mode"
• "Check what Polymarket markets are available for SOL"

Claude will run trader.js with the appropriate environment variables set.
