Scheduled Execution

This skill is designed for daily automated execution at 10:00 AM (UTC+8). To schedule via OpenClaw cron: # Create a cron job to run daily at 10:00 AM UTC+8 # This corresponds to 02:00 UTC The cron job should: Execute the analysis script Parse the JSON output Format a human-readable report Send the report to the user via messaging channel

Data Source

API: Binance Public API Endpoint: /api/v3/klines Rate Limits: 1200 request weight per minute (well within limits) No Authentication Required: Public market data

Timeframes

4h: 6 candles (24 hours of data) 1d: 30 candles (30 days of data)

Indicators Explained

RSI: Momentum oscillator (0-100). <30 = oversold, >70 = overbought SMA 20/50: Trend indicators. Price > both SMAs = bullish Support/Resistance: Recent low/high averages Price Change: Percentage change over specified period

Sentiment Logic

Sentiment is determined by combining multiple signals: RSI position (oversold/overbought/momentum) Price vs moving averages (trend direction) Recent price changes (momentum strength) Each signal contributes to a bullish/bearish score, which determines: Overall sentiment (Bullish/Bearish/Neutral) Confidence level (0.3 to 0.9) Detailed reasoning

Extending the Skill

To add more cryptocurrencies: Edit scripts/fetch_crypto_data.py and modify the symbols list: symbols = ["BTCUSDT", "ETHUSDT", "SOLUSDT", "ADAUSDT"] To add more indicators: Extend the calculate_technical_indicators() function with additional calculations (MACD, Bollinger Bands, etc.). To customize sentiment logic: Modify the analyze_sentiment() function to adjust weighting and thresholds.
