Fear & Greed Index
Market signalsIn short A 0–100 sentiment gauge for crypto markets. Low readings signal fear (potential oversold), high readings signal greed (potential overheating).
The number is assembled from volatility, volume, momentum, social chatter and dominance — all of which are consequences of price, so the index largely tells you where price has been, not where it is going. It is most useful at the extremes and as a check on your own state of mind: the readings that feel most obviously right are usually the ones everybody else is acting on too.
