Methodology

Stocks, flows, and proxies stay separate.

Liquidity Ocean standardises unlike series for comparison while preserving raw units, native frequency, lineage, overlap groups, and limitations.

Present readingNo numerical Macro Waterline is published. A regime can exist only when Reservoir and Pressure both clear their coverage gates.

This instrument is a method view. No value, direction, or macro score is inferred from missing coverage.

What this instrument is allowed to say.

Robust z-scores use rolling median and median absolute deviation.
Extreme values are capped for classification, while raw values remain visible.
Related observations nominate one primary measure instead of being summed twice.

Normalisation enables comparison, but it does not turn different economic concepts into the same thing or prove causation.

Raw units, transformation window, source vintage, method version, and overlap family travel with every result. The reserve-liquidity expression is a U.S. heuristic, not global liquidity or a capital-flow measure.
