Does the overnight gap work on NQ? Eighteen years, tested
The rule as it ran
Gap from yesterday's close, fade or follow. Run on NQ, the E-mini Nasdaq-100.
close 1600; signal 931; threshold 0.3; exit 1100; mode fade; sides Both
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.
Nothing in this record points at one thing to do differently by eye; the rule as written is what it is.
That is what the record says about the rule as written. It is not what next year says.

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 : E - The overnight gap
as you locked it:
The overnight gap, at the settings the door shows before anyone touches them (SHELF-01 v1.1): close 1600; signal 931; threshold 0.3; exit 1100; mode fade; 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

13. IF YOU TRADE THIS BY EYE
Nothing in this record points at one thing to do differently by eye; the rule as written is what it 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.
