Does opening-range retest work on NQ? Eighteen years, tested
The rule as it ran
Break of the opening range, pullback to the broken edge, first close back beyond it; follow or fade. Run on NQ, the E-mini Nasdaq-100.

One trade a day, the first signal in the window, on one-minute bars, with one tick of slippage each way and commission. Trades dated 2023 or later are the seen era; the years before decide the verdict. Tested September 15, 2026, under SHELF-01.
Against 5,000 coin flips the written rule is a coin (1484 of 5,000 matched or beat it on the unseen years); whatever you do on top of the written steps is where any edge is, and your fills are how to find out which part.
Everything this rule made, it made in the years you learned it in; the fifteen before them say the written rule is a coin, and whatever you do on top of it is where any edge is.

THINRIDGE ENGINE REPORT - SCORED UNDER PROTOCOL v1.1
==============================================================
SCOPE: Scored under Protocol v1.1 on FirstRate 1-min unadjusted via Thinridge engine. Intake testimony: NOT received (rule tested as locked). Contamination map sworn: no (seen era as declared or by archive date). Human review of reconciliation residue: NO.
1. THE RULE AS LOCKED
family : S - Opening-range retest
as you locked it:
Opening-range retest, at the settings the door shows before anyone touches them (SHELF-01 v1.1): range_start 930; range_min 15; last_entry 1130; exit 1530; min_range 0.0; mode follow; sides Both
seen era from 2023, the split the six teardowns were scored on
as the engine read it:
exit model : time only
filter : none
lineage : #1
bars : one-minute (every signal, fill and exit is on the one-minute series)
entries : one trade a day, the first qualifying signal in the window
history : 18.6 years, seen era = 2023 onward (declared by submitter, not sworn)
: trades dated 2023 or later are the seen era; trades before 2023 are the unseen era, and the unseen era decides the verdict
2. VERDICT
SCORE : 29 / 100
VERDICT : REJECTED
GATES : G7 era-manufactured edge (expectancy sign)
CRATERS : pillar(s) below 50%: II, III, IV, VI
Pillars : I=5 II=0 III=0 IV=5 V=12 VI=7

Exits: time 3943, $69,794.40
On the books, unseen era (net -$2,674.20): 10:00 -$35,031.40 11:00 -$53,749.60 12:00 -$18,760.00 13:00 -$10,515.00 14:00 -$8,240.00 15:00 $8,170.00
Eras: unseen -$2,674.20, seen $72,468.60; largest unseen year 2022 = n/a of the unseen net
Plateau: 47% retained on a 10% nudge; sign flip no
Drought: 173 months without a new high (ending 2023-07); median year -$2,747.00; years of median to recoup n/a
The era is the rule: the seen years carry all of $69,794.40; the unseen years made -$2,674.20. Longest wait for a new equity high: 173 months, median year -$2,747.00.
No next run is pointed at: no change fixes an era; the rule as written is the seen years' rule.
13. IF YOU TRADE THIS BY EYE
Against 5,000 coin flips the written rule is a coin (1484 of 5,000 matched or beat it on the unseen years); whatever you do on top of the written steps is where any edge is, and your fills are how to find out which part.
Everything this rule made, it made in the years you learned it in; the fifteen before them say the written rule is a coin, and whatever you do on top of it is where any edge is.
That is what the record says about the rule as written. It is not what next year says.
WHAT THIS CANNOT TELL YOU: the score assumes this rule walked in
once (see lineage) and that your development did not touch the
unseen era. Neither was sworn. A Thinridge audit exists to take
that testimony. Not investment advice. No guarantee of future
results. Statistical analysis of a mechanical rule as submitted.
