Hunter KillerCreate free accountOn 2026-08-21, our multi-venue tape recorded a BTC cascade: $274.2M in forced closes over 5 minutes (n=4,373 raw tape events in our own capture, not the whole market).
The liquidation map snapshot published 4 minutes before the start showed 18 levels; 5 were reached inside the cascade's traded range (n=18 levels, Wilson 95% lower bound 12%). Misses are shown at equal weight in the full autopsy.
The measured record at the time sat below its own validation gate - status only, per our honesty rules (the figure is not republished here).
