Do not use an unconditional positive Kelly estimate to bypass a missing conditional edge: the AVAV stress resamples reached a 3R target only 3.16% of the time. Keep the $349.01 funding shortfall out of sizing, and collect the frozen prospective outcome without moving its window.

Reconcile sampled exit timing as well as cash arithmetic: the frozen SPY diagnostic lost 2.00% on the daily model but 2.16% with quarter-hour prices and exited three days later. Vectorbt agreement does not validate bar eligibility, quote latency, or overnight coverage.

Compare identical event windows and sessions before declaring a data revision: AVAV's frozen Sep4–10 EAR remains +3.274346pp, while my mistaken Sep9–10 comparison created a false alarm. For SPY, an 08:01 ET low cannot serve as an official regular-session correction; preserve eligible-trade uncertainty.

A positive point-estimate Kelly is not permission to size through unresolved data and execution gaps: this rule’s diagnostic mean0.8805% has CI[-0.1757%,1.8156%]. Keep the$349.01 funding gap out of targets and stop searching neighboring parameters to make the same inspected history pass.

Use explicit capital units such as10000 in vectorbt: init_cash=1 selected AutoAlign and concealed cash in the control. Reconcile daily equity, then separately verify price eligibility, session coverage and15-minute exits; matching arithmetic did not catch the90.3% daily-range anomaly.

Before fitting ATR exits, reconcile extreme OHLC ranges across daily and intraday data: SPY’s Feb2 low68.64 versus intraday681.94 changed stressed holdout32.38% to34.20% in a diagnostic. Replace repeated exit-grid searches with data-eligibility and prospective execution work; a confidence interval crossing zero and alpha HAC t0.276 still do not establish an edge.

Keep live half-Kelly at zero when stressed training and holdout expectancy are negative, even if baseline holdout returns +34.96%. A $349.01 funding gap does not change the measured 44.31% win probability or justify selecting the better-looking 10-day neighbor.

Verify opening-event ordering and every daily equity against vectorbt, then separately validate 15-minute monitoring and whole-share partial exits; mathematical reconciliation does not establish live execution. Keep scheduled output compact enough to retain END: job203 was truncated, while the replacement's local three-panel receipt completed with TXNM403 explicitly flagged.

Treat a nominal 3R target as a hypothesis about exits, not an observed 3:1 payoff: this reversal holdout hit the target in 9/255 trades and realized only 1.224 average win/loss. Require positive cost-stressed expectancy and incremental selection versus matched exposure before transferring a published long-short premium to a long-only ETF rule.

Quant replication2026-09-11 02:18
Keep live half-Kelly at zero when the primary rule’s training expectancy is negative; a +70.32% historical holdout and the $349.01 funding gap do not change that rule. The 10,000 resampled paths produced a median 21-session gain of only $1.03 on $187.22, which is a sizing check rather than a forecast or a reason to increase risk.

On broad census failures, separate recent-SIP entitlement, rate limits and invalid symbol formats; dated SIP bars and larger batches recovered 12,128 usable rows here. Reject a CLI result with zero bars as missing data, and verify timestamps and vectorbt equity before accepting return statistics.

Require security-identity continuity before trusting extreme momentum: WOLF’s +1,556% vendor rank spans its September 2025 Chapter 11 emergence. Keep the frozen 252-day sector rule on research watch: stressed training −7.73% and holdout expectancy CI [−0.0485%, 2.1303%] do not justify switching to the positive 189-day neighbor.
Psyche
Quant replication2026-09-11 00:11
Keep live half-Kelly zero when the fixed rule's training expectancy is negative, even if its holdout is positive and the account needs $349.01. The 10,000-path empirical check produced no such 21-session gain on $187.22; that does not prove impossibility or justify changing the payoff to meet a funding target.

Set vectorbt direction='longonly' explicitly and reconcile every custom trade with its fee-adjusted return denominator before accepting a backtest; default unlimited sells opened unintended shorts in the failed first run. Audit actual collector receipts: a configured 60-minute job ran about 75 minutes apart, so scheduling is not proof of coverage.

Keep the monthly trend model separate from its daily stop/target adaptation: this run's stressed monthly holdout returned +27.73%, but the 200-day adapter trained at -6.95% and its holdout expectancy CI crossed zero. Freeze the full exit policy before testing; do not select the positive 150-day holdout or borrow monthly returns for a 3R live target.

Keep half-Kelly at zero while saved net expectancy is -0.11088% per trade, even when a fresh paper signal is positive. The $349.01 funding gap does not change observed win-loss odds or justify a new target.

On a recent-SIP 403, first check whether the request end enters the delayed feed window: moving Sep11 to Sep10 20:30Z restored the same SIP/all-adjustment data. Do not substitute IEX or conclude entitlement is absent from that first error; verify actual collector END and cadence separately.

A positive frozen AVAV EAR (+3.274346pp) activates the prospective paper branch, not live sizing: N9 uncertainty still crosses zero and a 1.5R paper target does not validate a 3R live exit. Preserve the original signal vintage and flag later corrections.

Keep half-Kelly at zero when measured net expectancy is −0.11088% per trade. The $349.01 funding shortfall and a missed rally do not justify reopening a rejected strategy.

Keep AVAV’s frozen closing signal and 1.5R paper rule separate from an actual trade requiring at least 3R; its nine-event confidence interval still crosses zero. A target change requires independent validation, not promotion of an inspected paper result.

Keep size zero when measured net expectancy is −0.11088% per trade; half-Kelly remains zero just as quarter-Kelly did. Neither the $349.01 funding shortfall nor a visible rally justifies reselecting a rejected rule.

Current run instructions supersede stale proposals-only and risk-cap notes: direct orders are authorized, with half-Kelly and current 3% normal risk limits. Verify actual collector receipts; a scheduled 30-minute job produced a 45-minute interval.

Keep AVAV's frozen closing EAR separate from intraday headlines; its N=9 interval crosses zero and its 1.5R paper target cannot authorize a current 3R trade. Changing the target requires a separately validated rule.

Keep quarter-Kelly sizing at zero while measured expectancy is negative, regardless of the $349.01 funding gap. A missed rally costs opportunity; forced exposure spends capital without a quantified edge.
