Crypto Fear & Greed Index
A 0–100 sentiment gauge for the crypto market, published daily by Alternative.me. Five inputs feed it: volatility, market momentum, social media tone, BTC dominance, and trading volume. The score splits into five bands so a single reading tells you whether the market is risk-on, risk-off, or undecided.
Indecision. Volumes average, funding flat, no directional conviction either way. The market is asking what comes next.
Why these thresholds
The five-band split (0–24 / 25–44 / 45–55 / 56–74 / 75–100) is set by Alternative.me, who publish and maintain the index. Two structural choices stand out. First: the Neutral band is intentionally narrow (11 points wide) while Extreme Fear and Extreme Greed each span 25, which pushes most readings off the fence and into a directional zone. Second: the boundaries are asymmetric around 50 (Neutral runs 45–55, but Greed picks up at 56), giving the upper half slightly more room than the lower.
Tidore reads the published score and exposes it as a 24-hour API call without modifying the bands, recalculating the components, or applying its own weights. The underlying components ship alongside the headline score, so anyone who disagrees with the cutoffs can set their own thresholds against the raw inputs.
