Fear & Greed Index

Use sentiment as regime context, not a trade command

A fear and greed score compresses several market observations into one number. That makes it easy to scan, but it also hides methodology, timing, missing inputs, and disagreement between components. An AI agent should retain that evidence before using the score in a brief, alert, or risk explanation.

Evidence to attach to every score

• Composite score, regime label, as-of time, change from the prior observation, and recent percentile or range.
• Component values and weights, transformations or inversions, lookback windows, and methodology version.
• Missing or delayed inputs, fallback values, confidence impact, and the next scheduled update.
• The role of the score in the workflow: context for a brief, alert-priority input, risk explanation, or research trigger.

Responsible interpretation: “Greed” describes the current risk-seeking regime; it does not identify what to buy, when to enter, or how much capital to commit. Preserve the evidence and combine it with the decision’s actual risk factors.
