status: CANDIDATE — generated by `python -m occams survey candidates` from survey record #9 (grid-002, seed 20260920); no standing, no alpha spent; registration is the author's `--yes` naming this cell's id (M12.5) tier: mechanism axis: price_daily relates_to: "TASKS-v4.md M12.5 · docs/adr/0039 · docs/surveys/grid-002-seed20260920.html#cell-9ed03d49b0d204e4"

Survey candidate 9ed03d49b0d204e4 — breakout_low on sp_100

A Draft: a proposed Hypothesis carrying a mechanism and a falsifier, with no standing until a human confirms its registration, which is the act that spends alpha. Nothing here has been measured on the measurement partition. Nothing here has cost anything. It was generated from a survey cell; the screen is not a verdict, and the shrinkage from screening 38,976 cells is recorded per question (N6, M12.6).

Mechanism

A buy-limit at the lowest low of the prior 20 bars, held for 20 bars, carries positive EV in net R on an S&P 100 constituent as listed on 2026-09-12 because a fall to a new low is over-sold and bought back (reversal at a new low)

The survey's cell file recorded the sentence as: A buy-limit at the lowest low of the prior 20 bars, held for 20 bars with no regime gate, carries positive EV in net R on an S&P 100 constituent as listed on 2026-09-12 because a fall to a new low is over-sold and bought back (reversal at a new low) — the proposer's wording on the day it ran; the sentence above is the grid's now, and registration stamps the recorded one beside it.

Universe sp_100, regime gate none, breakout_low(lookback=20) · limit, multi_day · hold 20 · stop percent 2 · target 2R.

Both interpretations

If true: the winner cell clears the declared floor and beats random entry at the corrected alpha on the measurement partition — the mechanism the survey screened is real after costs on this universe.
If false: the winner cell is not distinguishable from random entry after costs, or does not clear the floor — the screen's margin was selection, and the shrinkage says by how much.

Falsifier

The winner cell's EV in net R at or below the null's corrected quantile, or below the floor the author declares at registration, on the measurement partition.

What the survey showed — definition partition only, zero alpha, not a verdict

tier held · 12,069 trades · EV gross +0.205, net +0.154 at bounded costs
always-long at this geometry -0.093 over 77,363 · margin +0.247

lowest affordable floor at k = 4: 0.05 R; at k = 9: 0.05 R

Search space

The family's sweep — hold 1, 3, 5, 10, 20, stop 2, 3, 5, target 2, 3 — 30 cells; the accountant prices it at 0.3 alpha on the price_daily axis (rate × 30 cells).

Registration — the author's act

python -m occams question register --from-survey archive/surveys/grid-002-seed20260920-c6i.32xlarge --grid surveys/grid-002.toml --ids 9ed03d49b0d204e4 \

The floor is declared there, by the author; this document supplies none.
