Put/call ratio history (20-year stitched series)
Changed onEXCHANGE-WIDE daily put/call series per family (total, index, equity, etp, vix, spx), stitched from the frozen ratio archives (from 2006; spx from 2010) and the daily statistics feed (2019-10-07 onward). Dated definition edges are declared in definition_changes; response coverage (incl. any live-tail gap) is machine-readable in 'coverage'. Open-interest legs exist from 2019-10-07 only - the archive era is volume-only, declared null. Rules: rows filtered by [start, end]; dates after the committed dataset come from a bounded live tail; 'limit' keeps the NEWEST rows and sets truncated=true.
