b_stopband — stop-width band gate DEAD

Corpus lane — EN-26 (ledger-order column) · Scored and did not clear its own noise floor.

What it asks

Reject freak-width setups: the bit wants this trade's stop distance to sit within 0.5×–1.5× the median stop distance of the previous 20 signals.

Exact definition

Stop distance within [0.5, 1.5] x the trailing 20-SIGNAL median stop distance.

NOT a MarketView bit: the trailing median is a function of the previous 20 CANDIDATES, and the bit interface is f(candidate, view) with no access to other candidates. Computed instead as a ledger-order column in the screen script, strictly from candidates with an earlier decision_ct.

Fixed parameters & provenance

Every parameter below was fixed in the design document before any candidate value was computed. No sweep, no tuning: a bit that needs tuning to pass has failed.

Screen analytics — screen-2026-08-07

Conditional association on mean solo R, stratified on the count of the OTHER live bits, against a per-bit prevalence-matched null (50,000 i.i.d. Bernoulli draws at this bit's own prevalence, scored on its own strata). Population: 2,882 candidates, 2,289 filled, MES, 2019-06-04 → 2026-07-31.

Per era · reported separately, never pooled into a verdict — each cell is a smaller sample than the headline

Funnel & fill conditioning · a bit that mostly predicts whether a limit FILLS is not the same discovery as a bit that predicts whether a trade WINS

Novelty vs the six live bits · high agreement means the bit is mostly restating a gate that is already in the stack

By stratum — does it work where the method actually trades? · the live A/B take rule is count >= 4, so the count>=4 rows are the only ones that could change a live trade

Drop record — verbatim

NOT a MarketView bit: 'stop distance within [0.5, 1.5] x the trailing 20-SIGNAL median stop distance' is a function of the previous 20 CANDIDATES, and the bit interface is f(candidate, view) with no access to other candidates. It is computed instead as a ledger-order column in the screen script, strictly from candidates with an earlier decision_ct, and carries its own full-prefix causality proof (every candidate, not a sample) rather than the harness's sampled coverage.

Status — DEAD

NULL: pooled −0.015 R, matched p=0.840 (16.0th percentile), q=0.952. Its real contribution to the record is architectural. It is NOT a MarketView bit — 'the trailing 20 SIGNALS' is a function of previous CANDIDATES, and the bit interface f(candidate, view) has no access to those. It was therefore computed as a ledger-order column strictly from candidates with an earlier decision_ct, and it carries a stronger causality proof than any other column in the screen: full-prefix, every candidate recomputed from its own prefix (2,882 checked, 0 violations) plus 205 whole-column rebuilds on truncated ledgers with every retained row compared, 0 violations.

Retest path

None. The band is a hygiene rule that turned out not to be an edge; if it is ever wanted it should be argued as risk policy, not as a confluence.

Standing caveats

• Fill model optimistic: touch fills, zero net slippage, entry-bar SL/TP not checked inside the fill minute.
• Not a holdout — 2019-2026 was selected on, tuned on and reported on before this lab existed. A good number here means 'worth pre-registering', nothing more.
• MES only; the P1 edge is MES-centric and recent-regime.
• Masters miss four Sunday-evening blocks (May-Jun 2026); data ends 2026-07-31.
• Mean solo R is an average per candidate. The solo ledger is not a book and is never summed (PROTOCOL.md §0).
• Per-era cells are reported separately and are NOT pooled into a verdict; each is a smaller sample than the headline.
• Nothing on this page is TV-verified. A backtest number becomes actionable only after an independent TradingView Pine port reproduces entries AND per-trade PnL on a Deep Backtest export.
• Screening is not certification. Promotion requires all seven PROTOCOL gates, ending in a forward paired evaluation and a Pine referee.
