Call: No trade expected — flat, no_trade:no_signal, blocked = run_magnitude. Today's decision window is {Aug 12, 13, 14, 17, 18}, base = Aug 11 close — four of five bars (Aug 12–17) settled, only today's IWM close is live. The prior logged measurement through Aug 17's close was +1.16% (trades.csv 08-17 row), ~3.81pp short of the ±4.97% flag. To reach threshold today the window would need to land at +4.97% (a ~5% one-day IWM rally → contrarian short) or -4.97% (a ~5% one-day IWM collapse → contrarian long). Neither is plausible on a LOW-VIX (15.83), defensive-Dow-floor tape: the tech-led gap hits small caps modestly, but a ~5% single-session IWM move is a tail event (>3σ) that does not occur against a flat Dow and $91 oil. The up-run leg is dead; the down-run leg, marginally less implausible given the downside gap, is still ~4pp out of reach. State: FLAT (no open position, no scheduled exit in the 5-day cycle) — the ledger (position_ledger.json) confirms open_position: null; I remain flat, watching for a genuine extreme run to trigger a contrarian entry; today is not that day.
Sizing vs. event risk: Literally nothing to size — flat, no signal, no scheduled exit. (Had a flag somehow fired — the only conceivable case is a contrarian LONG on a -4.97% down-run — entry would be at TOMORROW's open, the morning of the FOMC Minutes, with the fixed 5-day hold spanning that event on day 1. That is inherent to the validated mechanism: no stop, no event-skip, no early exit is a locked design choice, and 15%-of-equity sizing was grounded in the worst-case historical tail (-19.66% on the 2020 COVID week ≈ -3% of equity). Noted for the record, not as an override.)
Session-character fit: None needed — SLACK is the firm's one swing stack; it checks IWM once for a completed multi-day measurement and is categorically indifferent to whether today is two-tier tech-down/value-up, news-driven, or low-vol. A tech-led gap with a Dow floor neither helps nor hurts a setup that is structurally far short of the flag either direction.
Key levels: None beyond the locked ±4.97% gate and the ~$300 / ~$292 / ~$291.6 structural references that feed future windows. Watch IWM vs ~$300 — a decisive break with genuine small-cap catch-up (IWM leading rather than lagging) is the only realistic fast path to a flag in the coming sessions; continued lag keeps every future measurement multiple points short. The week's macro fork (FOMC Minutes Wed, retail earnings Wed/Thu) is the forward catalyst that could finally give small caps the catch-up leg — but it lands on future windows, not today's.
Invalidation: No invalidation scenario applies — flat, no entry reachable (window structurally ~4pp short either direction), no scheduled exit. A no-trade day is the mechanism working as designed, not a failure: TEMPER's 2026-07-24 retrospective pre-registered range-bound-to-breaking IWM = structurally unreachable threshold = expected behavior, not edge degradation; my SPRT stays CONTINUE (n=0, LLR +0.000) — absence of setups is not evidence of degradation. The only event that changes my day is a firm-wide override (today GO, which changes nothing for a flat swing stack) or a confirmed flag — neither is reachable.
Forecast honesty (scored on calibration, not optimism): p_trade 0.01 — the floor. Unlike 08-17, today's window is not fully settled pre-market (it includes today's IWM close), so this is a slightly less-than-total certainty than a locked value — but the residual is confined to a tail-scale single-day IWM move that the tape makes implausible, not a plausible stretch, so 0.01 is honest. Direction none — at the logged +1.16% and with both legs ~4pp short, there is no lean worth expressing; even the less-implausible down-run (→ long) is far enough out of reach that expressing it would be noise, not signal. Conviction high — this no-trade call rests on a near-settled, script-verified measurement (+1.16% thru Aug 17) plus a structural read of today's defensive tape, so I'd stake more on it than on a live-print estimate; nothing in the two-tier gap-down or second-tier macro moves that near-settled number toward threshold.
paper_trade.py logs no_trade:no_signal (blocked=run_magnitude, near-miss telemetry = run through Aug 17 close, +1.16% vs ±4.97%, ~3.81pp short; window structurally ~4pp short either direction today). No contingency: the flag cannot reach threshold today without a tail-scale single-day IWM move.No trades taken.
