Real-time market sentiment tracking to guide your crypto trading and investment decisions
The Fear & Greed Index is a sentiment analysis tool that measures market psychology across the cryptocurrency market on a scale of 0 to 100. A reading below 25 indicates "Extreme Fear," while above 75 signals "Extreme Greed." The index aggregates multiple data sources to provide a single number representing whether investors are overly fearful (and likely to sell) or overly greedy (and likely to buy at peaks).
This metric has become essential for traders and long-term investors, as it helps identify potential market turning points when sentiment reaches extremes. Many institutional and retail investors use it as a contrarian indicator—buying when fear is extreme and reducing positions when greed is excessive.
The index uses a weighted formula combining six key market metrics:
These components are weighted and normalized on a 0-100 scale daily. Different providers may adjust weightings slightly, which is why you may see minor variations across platforms.
0-25: Extreme Fear
Market is heavily oversold. Historically a strong buying opportunity. Many investors are panic-selling, creating value for patient buyers.
26-45: Fear
Bearish sentiment prevails. Negative news dominates. Cautious accumulation may be warranted.
46-54: Neutral
Balanced sentiment. Markets are neither overbought nor oversold. Normal trading conditions.
55-74: Greed
Bullish sentiment rising. FOMO (fear of missing out) driving purchases. Consider taking partial profits.
75-100: Extreme Greed
Market euphoria. Asset prices stretched. High risk of pullback. Prudent time to reduce exposure or take profits.
The Fear & Greed Index has shown strong correlation with major market turns over several years:
Backtesting shows that buying during extreme fear (0-25) and selling during extreme greed (75-100) consistently outperformed buy-and-hold for swing traders, though long-term holders benefit from simply holding through both cycles.
When index drops to extreme fear, place buy orders. When it hits extreme greed, plan exit positions. This strategy works best on 1-3 month timeframes.
Use extreme fear as a signal to increase crypto allocation (buy dips) and extreme greed to reduce exposure (take profits). Automate this with dollar-cost averaging.
When greed is high (70+), reduce position sizes or set tighter stop-losses. When fear is extreme, you can afford larger positions with wider stops since asymmetric upside appears likely.
Don't trade on the index alone. Use it to confirm signals from technical analysis. Extreme fear + bullish technical pattern = strong buy signal. Extreme greed + bearish divergence = sell.

A reading of 20 indicates "Extreme Fear," typically signaling a potential buying opportunity. Historically, when fear reaches extreme levels (0-25), markets often recover shortly after as oversold assets rebound.
The index is updated daily, with some providers updating multiple times per day. The calculation uses a rolling average of market data from the past 24-48 hours to smooth volatility.
The index should not be your only signal. Use it alongside technical analysis, fundamentals, and risk management. It works best as a confirmation tool when combined with other indicators.
0-25 (Extreme Fear) suggests markets are oversold and may present buying opportunities. 75-100 (Extreme Greed) warns that markets may be overbought and a correction could occur.
Alternative.me is the most widely used and cited. CoinMarketCap and TradingView also provide versions. Each uses slightly different weightings, so comparing multiple sources gives better context.
It provides signals but is not a perfect predictor. It works well for identifying extreme sentiment levels, but markets can stay in extreme fear or greed for extended periods.
