The Fed didn't just hike — it flagged another hike this year, which means borrowing costs stay punishingly high for longer and the 10-year borrowing benchmark is already above 5%, a level not seen in decades. After the initial sell-off, futures are bounci

Verdict: well-built rules, unconfirmed trend — wait for ADX to arm

This idea has a real internal tension you need to understand before doing anything: the bearish macro case (a second flagged Fed hike, the 10-year above 5%) points one way, while the mechanical rules on QQQ and SPY are written as long-biased conditions with a 2.6% stop and 5.2% target. The strongest point for acting is the completed backtest — positive across all three windows, +13.5% over 60 months across 167 trades, with improving win rates and shrinking drawdowns (8.0%, then 7.1%, then 4.5%) in recent windows. The strongest point against is that the setup is not armed: SPY's ADX sits at 19.0 versus a required reading above 22 and QQQ's is at 7.9, roughly 14 points away, so no entry is live today. Compounding that, the parameter-sensitivity evaluation ran out of its time budget and established no robust nearby setup, so the published configuration stands unverified against variants, and the fundamentals cut both ways — look-through revenue growth is negative (QQQ top-10 at about -10.1% year over year, SPY's slice about -22.5%), yet margins are strong (53.6% gross and 28.4% net for QQQ's covered names), meaning the squeeze thesis must overcome genuine earnings power. We score thesis support mid-range because the macro catalyst per the September 16–17 Yahoo Finance and CNBC coverage is a close call and futures bounced after the initial sell-off. Set alerts and wait for ADX to confirm before committing capital.

Trade now: entry conditions are close but not fully armed

The entry conditions are two-thirds live on both tickers. On QQQ, the last close of $704.72 sits below the 21-day EMA at $712.41 (met) and RSI (14) at 37.0 is below the 50 threshold (met), but ADX (14) is 7.9 versus a required reading above 22 — roughly 14 points away. SPY is closer: at $754.05 the price is below its 21-day EMA at $762.99 (met), RSI at 31.1 clears the momentum filter (met), and ADX at 19.0 needs about 3 more points to cross 22. Until that last condition turns, the right action is a standing alert, not an order: be ready to act the day ADX confirms trend strength while price and momentum stay in range. If entries trigger, the plan is explicit: risk per position is capped at 2.6%, take-profit at 5.2% — roughly 2:1 reward to risk — a 40-session time exit, and support-based exits that activate if price closes below the second support level (QQQ: $695.25; SPY: $739.76). Position size is capped at 25% per name. The evidence read comes from completed backtest statistics on the QQQ daily pair: over 60 months the setup produced a 13.5% return across 167 trades with a 45.5% win rate and an 8.0% maximum drawdown; the shorter 24- and 12-month windows showed 7.0% and 4.0% returns with progressively better drawdowns (7.1% and 4.5%). Note the tension with the article's bearish thesis — these rules are written as long-biased conditions, so the macro short argument (Fed tightening, the 10-year above 5% per the thesis) and the mechanical rules point in opposite directions. That mismatch matters: follow the rules for the trigger, but know which book you're trading. One parameter caveat: the sensitivity evaluation ran out of its time budget before a robust nearby-parameter setup could be established, so the published configuration is the tested one as-is — no alternative tuning was validated.

The macro headwind is real, and the tactical rules engine banked gains through it

The idea's macro premise has genuine support in the cited coverage. Per Yahoo Finance's September 16, 2026 report, Wall Street went into the decision expecting a hike but flagged it as a close call — meaning the market was split on how restrictive policy would be. Per CNBC's live coverage dated September 17, the hike itself sparked a sell-off before futures recovered. That bounce is exactly the entry the idea wants: a better price to get short rather than chasing the initial drop, with the 10-year benchmark per the thesis above 5%, a level not seen in decades. The completed backtest evidence gives a concrete read on how a rules-based expression of this trade behaved. On daily QQQ/SPY bars over the last 60 months,…
