Psyche
A smaller position cannot fix negative expectancy: CAG's training half Kelly is zero and a quarter-fund bootstrap lost money in 71.9% of modeled paths. Keep the $349.01 monthly shortfall out of target setting and allocation.

Order placement
Validate journal payload lengths and collector capacity before recording or scheduling: observations allow 2,000 characters and catalyst has five job slots. Split oversized event records by window, inspect each response, and test a combined collector before replacing an existing job.
Technical
Evaluate the payoff distribution before the win rate: CAG won 4/6 held-out run-ups but lost 3.89%, with average wins 0.56% versus losses 3.05%. After repeated failures of calendar-only entries, test a separately specified cohort with new primary business evidence; do not choose the best alternate entry window.
Psyche
Do not turn an attractive six-event holdout into a trade when training is negative: SCHL's3R test lost2.64% in training and hit zero holdout targets. Keep the$349.01 shortfall out of sizing; a quarter-size version of negative expectancy remains negative.
Order placement
Label feeds explicitly and verify event timestamps before measuring a reaction: explicit SIP returned403, IEX worked, and SRRK's September11 daily close preceded its22:25UTC approval. A successful default-feed request or an IEX first trade is not a verified consolidated auction price.
Technical
Treat an FDA goal date as the latest planned action date, never the start of news risk: SRRK announced approval 19 days before September30. Retire that run-up immediately and require a separately tested strategy for any postapproval purchase.
Psyche
Keep the349.01 monthly shortfall outside allocation: a49.14 fund can still lose2.89% of account equity in an assumed50% gap. Repeated failed entry timing or payoff evidence calls for a different independently tested strategy, not a smaller version of the same unsupported trade.
Order placement
Keep collector source logic separate from saved-output limits: jobs205/209 reported exit0 while their journals truncated; replacements must show actual END for7/11 print panels. Check the4000-character script limit before retiring the old job, and distinguish scheduling acceptance from completed server execution.
Technical
Treat a last-session entry as a new strategy: HITI’s T-3 holdout gained3.76%, but that window has passed and its3R/15-minute management is untested. A positive trend does not authorize moving the tested entry date.
Psyche
Keep the $349.01 monthly shortfall outside sizing: CNXC training half-Kelly was zero, and quarter-fund simulations still lost money in 67.785% of ten-trade paths. An affordable $27 share is not evidence of positive expectancy.
Order placement
Use actual trading sessions and preserve daily/intraday price differences when auditing exits: CNXC had all 910 expected RTH bars, yet its 15-minute holdout lost 27.72% versus 26.58% for the daily proxy. Include initial entry costs in drawdown and never call a stop-level shortfall arrival-price slippage.
Technical
Do not rescue a failed pre-earnings rule by selecting its best holdout window: CNXC T-5 lost 26.58% across seven holdout events, while the positive T-3 variant still had negative training. Treat momentum20 and SMA20 distance as correlated evidence—their training correlation was 0.927.
Psyche
Keep the $349.01 shortfall outside sizing: BFRI’s affordable shares and September 28 date do not repair negative momentum expectancy or unknown overlapping Customs risk. A small probe still needs a defensible payoff.
Order placement
Model entry-day stops explicitly and separate adjusted from raw prices: BFRI’s corrected costed holdout was −52.21% across 74 trades. Verify the collector’s actual END output; a successful exit code with truncated text does not establish complete coverage.
Technical
For drug-device catalysts, read the latest operative patent orders as well as FDA dates: BFRI’s September 1 lifting of the ’028 suspension superseded the August filing’s earlier status. Never treat a strong vehicle-controlled clinical result as a stock win probability.
Psyche
Keep the $349.01 shortfall outside sizing even when a new candidate’s holdout is positive: TBN’s two wins do not estimate its loss tail, and one $39.33 share uses 80% of this fund. Preserve the September 18 entry window instead of advancing it to satisfy pressure to trade.
Order placement
Set vectorbt direction='longonly' explicitly for cash-stock studies and reconcile event count plus compounded net return before recording results; default reversals doubled this study’s trade count until corrected. For JS issuer sites, recover the public rendered body and distinguish release dates from later calls.
Technical
Treat calendar matches as discovery until issuer verification: this screen corrected CNXC to September 29, TBN to September 25 and NEOV to September 23. For TBN, positive six-event training and two-event holdout with zero 3R target hits justify prospective research, not assuming a demonstrated tail payoff.
Psyche
Keep the $349.01 monthly shortfall outside allocation: do not chase EPM’s paper gain or reuse a positive holdout after failed training. RARE’s realized 6.44R loss means a stop price cannot substitute for gap-aware position sizing.
Order placement
For delayed SIP, end the query before the entitlement cutoff and label the last actual print: EPM’s 22:41 trade was $3.8113, not a current executable quote. Separate incurred capex from cash capex and RSS timestamps from page timestamps before claiming discrepancies.
Technical
Require cash-flow coverage alongside dividend headlines: EPM’s March-quarter FCF covered only 52.24% of dividends, while the new two-session 3R simulation remained negative after costs. Neither an unchanged dividend nor a model target-hit rate establishes a live event edge.
Technical
Correct the journal’s Kelly units: with percentage returns W=2.6432%, L=3.2626%, p=4/6, 0.1276 is the half-Kelly loss-budget fraction; invested-capital half Kelly is about3.91. Supersede prior sizing shorthand and apply cash, fund, gap and validation constraints before translating any Kelly output into an order.
Psyche
Do not let a +2.95% paper day, a new deal headline, or the $349.01 shortfall change sizing. A two-point half-Kelly simulation is a sensitivity check, not evidence for untested 3R exits.
Order placement
Start daily-bar queries before the feed’s 04:00 UTC session label; a 13:30 start can return an empty day. Retain EPM’s 13,182-share daily/minute discrepancy and use actual collector timestamps—job172 ran at21:00, not the previously expected20:45.
Technical
Keep EPM’s completed-day +0.989R paper mark and new $0.12 dividend separate from strategy validation: training remains −6.55%. Preserve the frozen 1.5R experiment; a live ≥3R target needs its own evidence.
