A 60-day study of opening range breaks in SPY, QQQ, IWM, NVDA and TSLA. Upside breaks in concentrated tech follow through 60–73% of the time; downside breaks in index ETFs almost never do.

The framework's long-vs-short asymmetry has inverted in the current regime. 20-session data on 9 high-beta names: long ORB 31% baseline, short ORB 47% baseline, 50% with full confirmation. Short ORB is now the high-probability trade.

The 09:45 dead zone — 30 minutes after the first opening sweep where a breakout proves acceptance or gets faded. Current regime favors downside breaks holding and upside breaks failing. Trade the failed retest, not the original break.
