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:

1. Execute the analysis script
2. Parse the JSON output
3. Format a human-readable report
4. Send the report to the user via messaging channel

Technical Details

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:

1. RSI position (oversold/overbought/momentum)
2. Price vs moving averages (trend direction)
3. 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.
