agents/slack/performance/trades.csv, row 2026-09-15, blocked=run_magnitude) — 2.24pp short of the −4.97% flag. Flat book (agents/slack/state/position_ledger.json → open_position: null). Rates leg: 10-yr eased to ~4.99–5.00%, a hair below Monday's 19-year high — the pause that permits the mild bid, and the transmission check on any dot-plot outcome.Setup present: no. No trade expected — flat, no 5-day cycle in flight, no exit due, no entry reachable at today's open. p_trade 0.0, direction none, conviction high.
State-machine leg, stated plainly (this is where the position actually is). The ledger is {"open_position": null} — there is no open position, therefore no 5-day cycle in flight: no hold-silently marker, no close-and-log, nothing carried over today's FOMC at all. Today is day 0 of a cycle that has not started. At most one real trade per session is even possible for this stack (an entry at the open from a prior flagged close, or a scheduled close-and-log); neither leg is live — no position to hold or exit, and the entry test is against the run settled at the 09-15 close: −2.73%, 2.24pp short of ±4.97%. A real trade today is therefore mechanically excluded, not merely judged unlikely. Zero FOMC exposure, by structure.
The roll, bounded honestly. From −2.73%, a down-flag needs the reading to deepen ~2.24pp to −4.97%; an up-flag needs ~7.70pp to +4.97%. The reading's day-over-day change is composition-driven, not level-driven: today's close gives close(09-16)/close(09-09) − 1 where the 09-15 reading was close(09-15)/close(09-08) − 1 — both ends of the window roll at once, the base rotating off the 09-08 close as the measuring close advances. I hold no IWM closes for those dates (IWM absent from the Alpaca block; no IWM line in the scanner), and I will not invent one — so the output is a bound, not a point estimate. On a tape characterized as contained, two-sided and direction-undefined until 2:00 PM, with VIX at 16.97 (LOW), the base case is no flag settles at today's close. The honest pre-print position on a fully-priced binary is no position; that is what the gate is already giving me.
Today is a measurement day, not a trade day — and the measurement is bigger than usual, because today's close gates Thursday 09-17's open. If a flag were to settle at today's close, the contrarian entry would fire at 09-17's open and, under the locked mechanism (days_held counted as trading days strictly after entry, exit at days_held >= 5), would exit at the 09-23 close — spanning the FOMC aftermath (09-17), quad witching (Fri 09-18), and the S&P 500 / S&P 100 / Nasdaq-100 quarterly rebalance effective at Monday 09-21's open (BE/P/ILMN added; TAP/TTD/BLDR deleted; DELL/PANW/ANET/SNDK added to the S&P 100) — the quarter's largest passive-flow date. That holds standard 15%, no stand-down, no cut, for the three reasons already reasoned in the desk log: (1) the mechanism has no event-day override by design (strategy_v2.md Rule 6) and a plan-level stand-down is not mine to manufacture — no unilateral tweak; (2) an event-day entry is inside my cleared envelope, not outside it — 9 of 68 validated backtest trades entered on an event day, 8W/1L, net +$580.07, worst −$36.20 (−0.97% of notional), including 2024-09-18 (an FOMC decision day) and 2024-02-13 (CPI); n=9 is monitoring-grade, not proof, and I read it as "no case to stand down," not as a licence to claim event entries are better; (3) event risk is priced in the size — the ~$3,750 fixed notional exists precisely to absorb a stop-free 5-day hold through a week like this, calibrated against the worst trade in my history (−19.66% of notional, 2020 COVID week ≈ −3.0% of account equity). A discretionary cut for one particular calendar would be an untested deviation from a cleared mechanism; if an event-day filter should exist, the path is a fresh spec through the pipeline and TEMPER, not this plan.
Sizing / adjustments: none — standard operating procedure. Nothing to size: flat, no entry reachable at today's open, no scheduled exit. The locked 15%-of-equity fixed notional (≈$3,750 on the $25K account), single position, no stop-loss / no profit target / no early exit has no event-day or event-risk override, and today's HIGH event risk plus the firm-wide NO-GO are gate-irrelevant when the cycle says no-signal. The correct posture into the first rate move of 2026 for this stack is flat-because-unflagged, not flat-because-frightened — and today, for once, those coincide.
What I'm watching:
Invalidation: none applies — flat, no entry reachable at today's open (run −2.73% vs ±4.97%; a flag requires a several-percent single-session IWM close), no scheduled exit, nothing held into the print. This is regime, not calibration — TEMPER's pre-registered 2026-07-24 read holds: range-bound-to-breaking IWM = a structurally unreachable ±4.97% threshold = expected behavior, not edge degradation. Today is the 53rd consecutive logged session since Phase 3 began (07-02 → 09-16; the 08-07 duplicate row remains flagged for cleanup), roughly 3.0× the ~17-session expected inter-signal gap. The nearest Phase 3 graze remains 09-02's −2.95%, still 2.02pp away, with no cluster in either the −4.0%→−4.97% or +4.0%→+4.97% band. SPRT correctly sits at n=0, LLR +0.000, both boundaries (±2.944) untouched — absence of setups is not evidence of degradation and must not flag. No TEMPER conversation warranted. A no-trade day is the mechanism working as designed, not a failure.
no_trade:no_signal (blocked=run_magnitude; run −2.73% settled at the 09-15 close vs ±4.97%; flat book, no 5-day cycle in flight; next entry window = Thu 09-17's open if today's close flags a run, which would exit 09-23's close)No trades taken.
