YearBull turns dated market observations into a consistent independent research system. This page explains what YearBull calculates, which external inputs it uses, and how freshness, limitations, and corrections are handled.
What YearBull calculates
YearBull Rank, Bull Score, YB Market Risk, Cycle, and the Market Bull Index are calculated by YearBull from completed local datasets under the published YearBull methodology. They are YearBull analytical outputs, not vendor scores or trading recommendations.
- YearBull Rank orders the eligible analytical universe by relative market strength while preserving separate stable, infrastructure, and excluded states.
- Bull Score summarizes market-relative momentum, trend, drawdown, and liquidity conditions.
- YB Market Risk describes relative market volatility and stress; it is not an investment-safety rating.
- Cycle places the current analytical state into an Early, Mid, or Late phase.
- Market Bull Index combines trend, breadth, risk, liquidity, and market structure into a market-level reading.
Current external market-data source
For quantitative inputs, CoinGecko provides price, market capitalization, reported trading volume, circulating, total, and maximum supply where available; exchange reported volume, observed tickers and pairs, venue metadata, and the external Trust Rank. These inputs do not determine YearBull’s methodology or conclusions. Trust Rank is not proof of reserves, solvency, licensing, custody quality, or withdrawal availability.
How YearBull uses the inputs
YearBull stores dated snapshots locally, validates and normalizes fields, preserves explicit unavailable states, and calculates its metrics from completed datasets. Exchange coverage, pair and currency concentration, median spread summaries, and related presentation fields are derived by YearBull from the stored observations.
Public pages read from the YearBull database and cache. Opening a profile does not trigger a request to an upstream provider, and the displayed values are not live execution quotes.
Freshness and limitations
The data date or last-checked date shown on a profile is the relevant freshness reference. Values can be delayed, incomplete, unavailable, or revised, and market movement after the displayed timestamp does not by itself indicate an error. Each metric should be read together with its coverage, methodology, and stated limitations.
Editorial sources and quality controls
Project, network, exchange, technical-documentation, and source-repository links are included where available. Project-authored claims are treated as primary-source statements rather than independent verification. YearBull documents material methodology changes, keeps dated analytical records, and separates external observations from its own calculations and editorial interpretation.
Methods and corrections
