Forced selling in $QQQ is stacking three ways into Friday OpEx. Price is under the 50-day and below the gamma flip at 719. Dark pools printed 73% short volume yesterday, that distribution is mechanical, not discretionary profit taking. Lose the 50-day and CTAs start cutting Nasdaq exposure. Negative gamma means market makers sell into every bit of weakness on top of that. Three flows, one direction: a clear path toward the 710 put wall. Meanwhile the rest of the market still enjoys long-gamma dampening, so the tape looks fine. Classic two-speed OpEx, tech gets forced while the index pins. History says the weak sleeve usually tags its wall before the weekend. Consensus treats every tech dip as a buy signal here. I'm staying light on tech longs until price reclaims 719. If 710 breaks on volume, next support cluster sits near 693-700. How far do you let mechanical flow run before stepping in?
