dvcrn Polymarket AutoTrader
Automatically trades BTC, ETH, SOL, and XRP price prediction markets on Polymarket using short-term technical analysis signals.
How It Works
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.
Market Discovery — Queries the Polymarket Gamma API to find active, unclosed price prediction markets for the relevant asset expiring soon.
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
Billing — Each cycle deducts 0.001 USDT via SkillPay before executing. If balance is insufficient, a top-up link is returned.
Scheduler — Runs automatically every 5 or 15 minutes (set via
TRADE_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.
