About this skill

Analyzing Market Sentiment

Overview

Cryptocurrency market sentiment analysis combining Fear & Greed Index, news keyword analysis, and price/volume momentum into a composite 0-100 score.

Prerequisites

  1. Python 3.8+ installed
  2. Dependencies: pip install requests
  3. Internet connectivity for API access (Alternative.me, CoinGecko)
  4. Optional: crypto-news-aggregator skill for enhanced news analysis

Instructions

  1. Assess user intent - determine what analysis is needed:

    • Overall market: no specific coin, general sentiment
    • Coin-specific: extract symbol (BTC, ETH, etc.)
    • Quick vs detailed: quick score or full component breakdown
  2. Run sentiment analysis with appropriate options:

    # Quick market sentiment check
    python ${CLAUDE_SKILL_DIR}/scripts/sentiment_analyzer.py
    
    # Coin-specific sentiment
    python ${CLAUDE_SKILL_DIR}/scripts/sentiment_analyzer.py --coin BTC
    
    # Detailed breakdown with all components
    python ${CLAUDE_SKILL_DIR}/scripts/sentiment_analyzer.py --detailed
    
    # Custom time period
    python ${CLAUDE_SKILL_DIR}/scripts/sentiment_analyzer.py --period 7d --detailed
    
  3. Export results for trading models or analysis:

    python ${CLAUDE_SKILL_DIR}/scripts/sentiment_analyzer.py --format json --output sentiment.json
    
  4. Present results to the user:

    • Show composite score and classification prominently
    • Explain what the sentiment reading means
    • Highlight extreme readings (potential contrarian signals)
    • For detailed mode, show component breakdown with weights

Output

Composite sentiment score (0-100) with classification and weighted component breakdown. Extreme readings serve as contrarian indicators:
