learn.whatIsHeading

The Crypto Fear and Greed Index Calculator computes a composite sentiment score from 0 (extreme fear) to 100 (extreme greed) using weighted inputs including volatility, market momentum, social media sentiment, BTC dominance, and Google Trends data.

Formel

Index = (Volatility Score × 25%) + (Momentum Score × 25%) + (Social Score × 15%) + (Dominance Score × 10%) + (Trends Score × 10%) + (Survey Score × 15%)

V: Volatility Score (0-100) — Inverse volatility score — high volatility = low score (fear)
M: Momentum Score (0-100) — Market momentum relative to 30/90-day moving averages
S: Social Score (0-100) — Social media volume and sentiment from Twitter/Reddit
D: Dominance Score (0-100) — Bitcoin dominance trend (rising = fear, falling = greed/altcoin speculation)

Schritt-für-Schritt-Anleitung

1Gather input metrics: BTC volatility (30-day), momentum (vs 30/90 day averages), social media volume
2Score each component from 0-100 based on historical percentile ranking
3Apply the weighting formula to compute the composite index value
4Interpret: 0-25 = extreme fear (buy signal), 75-100 = extreme greed (caution signal)

Häufig gestellte Fragen

Is the Fear and Greed Index a good trading indicator?

Historically, buying during extreme fear (<20) and selling during extreme greed (>80) has been profitable over multi-month horizons. However, it is a lagging/coincident indicator and should not be used alone for timing trades.

How often is the index updated?

The index is calculated daily using the previous 24 hours of data. Some providers also offer hourly updates. The most commonly referenced version is from alternative.me, updated once per day.
