    Market Breadth & Regime Indicators for Crypto Trading

    6 market breadth & regime indicators, from the AlgoBrain wiki. The state of the whole market: breadth, dominance and regime classifiers that gate other signals. Each lists what it measures, the strategies that use it, the Crypto Data API endpoints that serve it or its inputs, and a prompt for an AI agent to compute it. All of them are in the API: GET /api/v1/indicators/catalog?group=market-breadth-regime.

    6 indicators Most-used by: Alt-Season Momentum Gate (Dominance / Alt-Season Gate), Breakout and Retest (Hyperliquid Basket), Cross-Sectional Relative Value (Hyperliquid Basket), Failed Breakout / Failed Breakdown (Hyperliquid Basket), Liquidity-Vacuum Momentum (Hyperliquid Basket)

    Every Market Breadth & Regime indicator

    Advance/Decline Line #

    Advance-Decline LineA/D LineAD LineAdvance/Decline LineBreadth Line

    The advance/decline line (A/D line) is the foundational market-breadth indicator: a cumulative running total of the number of advancing stocks minus declining stocks each day.

    Used by A building block; no catalogue strategy declares it directly.

    Breadth Thrust #

    Breadth Thrustbreadth-thrustZweig Breadth ThrustBreadth Thrust Indicator

    A breadth thrust is a market breadth momentum signal that marks a violent, broad shift from an oversold market to overwhelming buying pressure across a very large share of stocks.

    Used by A building block; no catalogue strategy declares it directly.

    Financial Conditions #

    financial conditionsfinancial conditions indexFCI

    Financial conditions measure the overall ease or tightness of credit, funding, and risk appetite across the financial system. They are the real-time transmission mechanism of monetary policy — the channel through which central bank decisions actually reach the real economy.

    Used by A building block; no catalogue strategy declares it directly.

    Fractal Dimension #

    Fractal DimensionFractal Dimension IndexFDIBox-Counting DimensionPath Roughness

    Fractal dimension (D) measures how thoroughly a path fills the space it moves through. A perfectly straight line has D = 1; a path so convoluted that it effectively covers a two-dimensional area has D = 2.
