Polymarket AutoTrader

# Polymarket AutoTrader

Automatically trades BTC, ETH, SOL, and XRP price prediction markets on [Polymarket](https://polymarket.com) 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`).
