Each gauge is 0–100, the weighted mean of its inputs' ranks within trailing 10- or 20-year windows (50: the inputs at their window medians), the record since 1981. The regime and the three gauges use today's data; Economic Breadth and Housing use the revised monthly record.
43 indicators feed the site's composites · 23 of them feed the three gauges · the record since 1981 · fixed rules, written down · every figure traced to its source · revisions kept
Each cell is one indicator, colored against its own historical thresholds.
Some map the state of the economy; others read the market. They are not the same question, and the site keeps them apart.
