Every estimated off-exchange-share record Tapeboard has captured, one frozen page per market day: the highest-share US names with their CNMS off-exchange volume, short volume and consolidated volume. 5 daily records, most recent first. Every share is an estimate: estimated off-exchange share — media-reported trades only, includes internalizers/wholesalers, not per-ATS, understates weekly FINRA totals by ~10–15%.
