Volatility spike events — the archive 155 archived

Volatility events are two-sided moves: price ran hard in one direction and then reversed, with neither the up nor the down leg dominating cleanly. They often appear around macro prints (a spike then fade), thin-session wicks, or brief loss-of-liquidity episodes. The archive uses this shape label when the net move is small but the peak excursion was significant — a round-trip that would have liquidated anyone who did not manage their stops.
