MACD is a specific Trading coordinate in the Bitcoin knowledge graph. In practical terms, it identifies the subject described here: The relationship between two exponential averages, displayed with a signal line and histogram. This definition is narrower than promotional usage and should be read together with the implementation, date and evidence attached to the entry.
MACD is best understood as part of a system rather than as an isolated definition. Its related coordinates show the mechanisms, incentives and historical records that give the term practical meaning.
MACD describes how participants value, trade or obtain exposure to bitcoin. Market behavior can affect adoption and mining economics, but it does not rewrite consensus rules. Price evidence and protocol evidence answer different questions.
Understanding MACD helps distinguish a verifiable Bitcoin mechanism or historical record from slogans, products and market narratives.
Primary or authoritative records make these details checkable: moving average convergence divergence subtracts one exponential moving average from another and compares the result with a signal average; every calculation needs price field, periods, initialization and timeframe. They should be verified before using the coordinate in analysis.
The practical limit is: MACD is a transformed history of price, not independent information or a causal forecast; crossover rules lag, behave differently by regime and can be overfit through parameter, asset and sample selection. A definition, office, chart pattern or published claim is not by itself a prediction or Bitcoin consensus rule.
