The signals behind the verdict
The tracker counts 15 live signals and calls a bull market on a strict majority. Fear & Greed and ETF flows each cast two votes (F&G a level and a trend; ETF two non-overlapping flow windows), so those 15 votes live across the 13 explainer pages below, plus seven context indicators that are shown but never counted.
They are chosen to disagree with each other. Four read the price series over different horizons, which makes them fast but correlated. Institutional flows (ETF flows and stablecoin supply) measure settled money rather than sentiment, and move on a different clock. Retail attention (Coinbase app rank, Google Trends) tends to run hot late in a cycle. On-chain activity (miner revenue, active addresses) is the slowest to fake, because it counts what people actually did.
A single indicator is easy to argue with, which is the point of counting fifteen. Each has a fixed, published threshold, and a failed data source is excluded from the vote rather than counted against the market. The exact rules, and an honest note on how correlated these really are, sit on the methodology page. For background on cycles themselves, see the guides.
