Shared Market Read

• Event risk today: HIGH — Durable Goods Orders at 8:30 AM ET. This is the most consequential week of the year: FOMC July 29 (Wed, 2 days), PCE July 30 (Thu, 3 days), mega-cap earnings (META, MSFT, AMZN, AAPL) Wed–Thu. The US-Iran ceasefire and Brent collapse (-9.6%) transform the macro landscape entering the week. None of which matters to VESPER — the overnight hold is unconditional.
• Session character expected: Recovery rally / gap-up on ceasefire relief. Futures sharply higher (SPY +0.88%, NQ +1.44%). The oil collapse is the dominant pre-market driver — energy (XLE) sells off hard, while transports, airlines, and consumer discretionary benefit. Potential fade into afternoon if Durable Goods disappoints or pre-FOMC positioning takes over. The intraday tape is rich but irrelevant to my desk.
• VIX regime: 17.57 (LOW — crossed back from MID <18 over the weekend on ceasefire news). VESPER has no VIX filter — holds through all regimes. The backtest's 2023–24 holdout (5.57 bps/day net) covered every VIX regime.
• Key levels: SPY prior close 738.90, futures +0.88% suggesting a gap-up open near ~745. SMA20 746.15 (below SMA20), ATR(14) 7.01. The only level that matters for VESPER: tonight's 16:00 auction-inclusive close, which sets the entry anchor.
• Macro backdrop: US-Iran ceasefire transforms the week's dominant macro risk. Oil collapsed 9.6% (Brent $88.96), reversing the oil-risk premium that built up through July. Stock futures rallying sharply on the relief. 10-year yield at 4.69% (down from 4.71%). VESPER holds through all of it — the overnight premium is paid for bearing these gaps.

VESPER — SPY (unconditional overnight hold)

p_trade: 1.0 | direction: long | conviction: high

Summary: The strategy is unconditional — every session, every night, no exceptions. The only content worth stating is the position status, kill/watch distances, and the realized-cost check.

Position status (from ledger): Long SPY at $738.75 — entered 2026-07-24 at 16:00 ET MOC anchor. 30.00 shares, $22,164.64 notional (90% of equity at entry). Held over the weekend (Friday close → Monday open), awaiting 09:31 ET exit.

Exit today (09:31 ET): Marketable-limit sell at 09:30:00 ET, flat by 09:31. The US-Iran ceasefire and oil collapse produced a sharp rally in S&P 500 futures (+0.88%) — this should be a favorable exit after a rough stretch of 5 losses in the last 7 cycles. The weekend hold (Friday→Monday) is a single observation in the backtest — the overnight premium spans the calendar gap. The pre-market gap-up is a tailwind.

Entry tonight (16:00 ET): Unconditional MOC buy SPY at 16:00 ET. Standard sizing: 90% of projected equity. The overnight premium does not care about today's Durable Goods print, ceasefire-driven intraday rotation, or the FOMC overhead. The clientele segmentation edge is a property of the session boundary, not of tonight's specific catalyst mix.

FOMC week note: The FOMC decision is Wednesday (July 29) at 2:00 PM ET. VESPER holds through FOMC nights unconditionally — the backtest's 1759-cycle sample includes every FOMC night. The backtest's 2023–24 holdout (5.57 bps/day net) covers every FOMC, CPI, and NFP night in the sample. The COVID -26.52% drawdown is the validated in-sample worst. Tonight's entry is one of ~250 annual observations. The FOMC decision is noise on that scale.

Mechanism watch status: OK — trailing-250 +8.277 bps, trailing-500 +4.995 bps (as of last cache edge, prior to tonight's cycle). Both well above the 0.655 bps/day kill floor. The recent stretch of losses (5 of 7 cycles losing) is normal single-session noise (σ = 88.6 bps/day) — the trailing-250 mean will tick one observation forward but should remain decisively above floor. The weekend gap (Friday close → Monday open) is a longer observation window but is mechanically encompassed by the backtest's measurement convention.

Execution-cost SPRT: CONTINUE — n=7, LLR +2.625 (+0.319 to CONSISTENT at +2.944; -5.569 to DEGRADED at -2.944). In simulation the ledger prices at the anchors, so shortfall ≡ 0. The monitor is decision-relevant only against real broker fills. The budgeted round-trip cost of ≤ 1.0 bps/day remains the binding operational constraint.

What I'm watching: (1) 09:31 exit fill quality — the ceasefire-driven gap-up should produce a clean exit, favorable after the recent losing stretch; (2) the 16:00 close anchor price — Monday sessions often see elevated opening volume; the entry anchor's precision depends on the auction-inclusive 16:00 bar; (3) mechanism watch update after tonight's cycle closes — the trailing-250 mean will update with the weekend observation; expected to remain well above the 0.655 bps/day floor.

Invalidation: VESPER does not invalidate — the strategy is unconditional. The only invalidation path is a Mechanism Watch trigger (trailing-250 AND trailing-500 < 0.655 bps/day, confirmed by two-window P12 protocol), which would initiate a TEMPER review. No such conditions are present.
