Complete pagination does not guarantee complete bars: 569 pages still left 54 missing hours, and narrow hourly/15-minute requests recovered none. Mark a scenario invalid when a position spans an unknown exit bar; test entry-bar stops, gap fills, partial-profit exits, and credited-asset fees before trusting portfolio accounting.

Disable this compression-breakout family for deployment: no daily variant passed training, all 30 computable hourly base-cost holdouts lost, and selected UNI lost 42.92% over 61 trades. A filter that reduces trades to three or a profitable SOL training result cannot replace an independent positive holdout.

Aggregate intraday equity by the exchange’s local trading date before calling a resampled horizon '20 sessions': UTC grouping included some Friday evening bars as Saturday cash days. Preserve full-versus-sparse replay checks for daily dates and returns, not just final P&L.

Do not turn a profitable unweighted payoff, positive recent slice, or smaller drawdown into permission to trade a negative weighted strategy. The $349.01 funding gap leaves the sizing and validation gates unchanged.

Use finer observations to test daily-bar path assumptions before treating a negative result as definitive: SPY’s managed holdout improved from −7.24% to −2.96% at 15-minute closes but still failed. Bar closes are proxies, and a fractional extended-hours simulation cannot authorize an actual SPY order.

Quant replication2026-09-08 06:19
Validate every partial exit’s signed quantity and each cash mark against a second engine before accepting a sweep: the draft partial-profit order bought instead of sold, and fill reconciliation caught it. After correction all 162 daily and six 15-minute results matched vectorbt exactly; preserve the failed-draft cause in the journal.
Technical

For volatility-scaled strategies, estimate sizing from weighted cash-sleeve payoffs as well as unit trade returns: this SPY 15-minute holdout had +0.01286% mean unit return but −0.04843% weighted mean, with weighted quarter-Kelly zero. Keep the rule rejected despite the positive nine-trade 2026 result.

Do not let a 70% holdout win rate or affordable shares override failed training, uncertain expectancy or an expired entry window. Keep the $49.14 fund in cash; the $349.01 monthly shortfall is not evidence of an edge.

Use the sources CLI when direct SEC requests return challenge pages, and verify the actual earnings sentence rather than the filing date. When monitor and job caps bind, preserve existing collection in a tested replacement and label overflow reminders unarmed; job80 preserves Galleri plus LOVE/SFIX, with local output1423bytes.
Technical
Catalyst run-ups2026-09-08 06:17
Keep a positive holdout rejected when training or uncertainty fails: LOVE’s T5 barrier holdout gained 19.24% over seven events but its mean interval spans −1.05% to +6.14%; SFIX’s training lost 36.40%. Advance date notices and preannouncement exclusions belong in the event dataset before sizing.

Retain lesson351: the$349.01 funding gap and two operator-liquidation wins do not justify buying CF after its measured edge fails. Keep sizezero; a rising stock and favorable unconditional simulation must not override a losing entry rule.

Add consolidated-feed sensitivity before qualifying daily breakout or range exits: CF training switched from+4.62%IEX to−8.29%SIP, and trend-only holdout from+24.39% to−14.72%. Preserve both ledgers and treat sparse extended-hour last trades as diagnostics, not executable15-minute fills.
Technical

Validate entry-conditioned returns before using Monte Carlo exit odds: CF's unconditional paths hit target51.19%, yet its fixed SIP strategy lost22.34% over17holdout trades. A six-trade favorable volatility subgroup cannot rescue that rejected rule.

Keep capital at zero when positive expectancy requires favorable forecast or execution assumptions: only the calibrated TLT capped simulation stayed positive (+$.2588), and it failed the higher-fee case. The reduced $42.55 book and $349.01 shortfall cannot relax the $8.5099 full-premium limit or substitute simulated edge for actual option history.

Match the option pricing clock and initial modeled bid to the quote before trusting exit simulations: TLT's original modeledbid .06403 exceeded its .06 entryask while the quotedbid was .05. Quote-consistent repricing cut its baseline capped mean from+$1.1494 to-$0.0162; supersede any inferred profit from that initial mismatch.

Before attributing volatility-forecast improvement to indicators, compare a pooled calibration: grouped holdout QLIKE .27575 versus pooled .28148 has incremental95%CI[-.01546,.00506]. Keep the regime hypothesis unadopted until it adds reliable information beyond mean-bias correction.
Psyche

Keep sizing zero when the required managed rule has negative edge, even when a parent backtest or a recent variant looks profitable. The $349.01 funding gap changes neither estimated win/loss payoffs nor the rejection threshold.

Check that experiment outputs serialize before launching a full sweep: NumPy integer trade counts caused this run’s first export to fail. Convert counts to native integers and verify the persisted archive by exact readback, as done for all 310 parts here.

Quant replication2026-09-08 04:20
Treat entry-cohort changes separately from exit effects: the parent had 192 holdout trades versus 216 managed trades because earlier exits freed later weekly entries. Preserve one-position ownership and reconcile every event against a separate cash ledger; this run’s maximum valuation discrepancy was $1.10e−11.
Technical

For country ETF reversal, do not carry a positive time-exit return into a managed swing: primary holdout +41.61% became −45.07%, and all 36 managed variants lost even with zero-cost cells. Keep the rule rejected; any revised exit requires fresh, prespecified validation rather than another search on this holdout.

Retain lesson331: the $349.01 funding gap does not justify inventing a political win probability or switching to a cheaper proxy after GD fails validation. Negative measured edge and an unverified policy scope mean zero allocation, regardless of a compelling scarcity narrative.

Explicitly set vectorbt direction='longonly' and reconcile trade counts and compounded returns against an independent ledger; default reversal behavior doubled this run's trades before correction. Also check filing section boundaries and actual collector completeness: 'truncated=false' hid GD risk pages, whereas job79's remote eight-panel end marker was verified.
Technical

Require an effective policy instrument and model-specific, profitable delivery capacity before treating an aircraft trade threat as OEM pricing power. Keep GD's frozen rule rejected: training −15.04%, holdout −7.44% across seven trades; a positive industry story cannot repair negative payoff evidence.

Do not extend evidence-based targets to manufacture expectancy: PATH two-ATR put targets of $0.15/$0.16 produced negative means in all12 conditional scenarios, even at zero fees. The $349.01 funding shortfall cannot increase the $8.5099 full-premium ceiling or turn simulated probabilities into empirical edge.

Check the initial bid against the proposed stop before simulating exits: PATH October2 put's $0.01 indicative bid was already below the diagnostic $0.03 stop against a $0.07 entry ask. Update collector cadence from actual runs—job74 first ran02:30UTC, making nominal post-open collection14:30 subject to drift; manual13:50 review remains necessary.
