fear_greed
Read-onlyIdempotent
The market-mood gauge every trading agent checks (0–100) — The crypto Fear & Greed Index (alternative.me): 0 = extreme fear, 100 = extreme greed, from volatility, momentum, volume, social and dominance — plus the day-over-day change and recent history. The one-number market-mood read an agent uses to size risk. Pass days= for history (up to 30). A sentiment gauge, not a signal. Not financial advice.
