Régime intrajournalier contrasté et peu lisible : détente du VIX et des rendements américains favorable au risque, mais indices américains encore sous leurs moyennes horaires principales et divergents entre eux. Le dollar recule fortement, tandis que EUR/USD et GBP/USD sont déjà surachetés à court terme. Les minutes du FOMC dans moins de deux heures augmentent fortement le risque de retournement et de volatilité.

HOLD^SPX

The long thesis remains intact: SPX is above entry, above its 20-hour, 50-hour, 50-day and 200-day averages, and above the 7418 invalidation, with positive 24-hour momentum and support from a low, falling VIX. Hold unchanged because the market is closed and data are stale; nearby 7512-7526 resistance, elevated yields, Nasdaq underperformance and weekend gap risk do not provide a defensible basis to update or close.

Journée de repricing macro violent contre le dollar, mais qui ne se transmet pas aux actions. Le dollar est vendu contre tout le bloc : EUR/USD +0,78% à 1,1667, GBP/USD +0,55% à 1,3607, USD/JPY -0,70% à 158,45. Le 10 ans américain perd 5,9 pb à 4,651 et l'or explose de +3,58% à 4548, soit +2,93% sur 24h après avoir traversé sa SMA20 horaire de 4428 en une seule bougie (12:00Z). Le VIX recule de 4,40% à 15,22, sous sa SMA50 journalière de 17,03. Tout l'appareil de mesure pointe vers un assouplissement anticipé des conditions financières. Le problème est la contrepartie manquante : les actions ne suivent pas. Le S&P 500 ne gagne que 0,12% à 7726 et reste sous sa SMA20 horaire (7741) et sa SMA50 horaire (7754) ; le Nasdaq 100 est en baisse de 0,22% à 29514, à 280 points sous ses deux moyennes horaires, malgré un rebond franc depuis son plus bas de 29292. Sur sept jours les deux indices sont négatifs (-0,47% et -0,12%). Une baisse des taux et une baisse de la volatilité qui n'achètent pas d'actions, avec l'or en tête du mouvement, ressemblent davantage à une prime de débasement ou de risque budgétaire qu'à un régime de reflation, et cette lecture n'est pas favorable aux indices. L'Europe est fermée (CAC et DAX, réouverture 20/08 07:00Z) et termine faible, le CAC clôturant à 8501,91 exactement sur son plus bas du jour, RSI horaire à 26,83. Les instruments porteurs du signal le plus net (or, baril, USD/JPY, VIX, 10 ans) sont tous non négociables en simulation ; le champ éligible se réduit au S&P 500, au Nasdaq 100, à l'EUR/USD et au GBP/USD. Régime : extension généralisée, direction non confirmée par les actifs risqués, à moins de deux heures d'un événement à fort impact.

HOLDGBPUSD

Opened only one slot ago and the premise is unchanged: 1.3299 is still below 1h SMA20/50 (1.33049/1.33204) and daily SMA50/200 (1.33459/1.34162), and GBP remains the weakest major (-0.43% 24h, -1.06% 7d). Price is retesting the broken prior-week low at 1.33003 from below rather than reclaiming it, and 1h RSI 42.44 with daily RSI 36.66 keeps the trend bearish without being extreme. Stop 1.3322 still has 2.35x 1h ATR of room at 0.038% of capital risk, and the -0.31R mark is ordinary entry noise, not evidence against the thesis. No change to stop 1.3322 / target 1.3230.

HOLD^CAC

Price 8406.06 still holds above the 8380 stop (0.31%, 0.95x 1h ATR) and above 1h SMA20/50 (8376.29/8373.88) and daily SMA50/200 (8309.32/8179.21), with +80.26 unrealized and the stop already locking in gain. VIX at 18.67 has not breached the stated 20 invalidation despite soft US equities and the oil selloff, so the thesis is not broken. The Europe cash session is closed until 2026-07-28T07:02 UTC and execution requires an open session, so no stop tightening or exit is executable this slot; leaving stop 8380 / target 8550 unchanged rather than pre-tightening into an overnight gap.

HOLDEURUSD

Short remains structurally correct: 1.1377 is below 1h SMA20/50 (1.13855/1.13866) and well below daily SMA50/200 (1.14019/1.16070), with 24h -0.35% and 7d -0.40%. The bounce off 1.1365 is shallow and 1h RSI at 43.96 is neutral, not a reversal signal; stop 1.1389 still has 1.49x 1h ATR of room and risk at stop is only 0.034% of capital. VIX has not confirmed the return of risk appetite that would invalidate the thesis. No change to stop 1.1389 / target 1.1330; not chasing the stop tighter ahead of the 14:00 UTC CB Consumer Confidence print.

OPENGBPUSD

Adding the strongest relative-weakness expression of the dollar theme already in the book, with size cut to 12,000 units (~$15.9k notional, ~$36 risk at stop, 0.036% of capital) precisely because it is correlated with the existing EURUSD short; the stop is set ~2.9x the 1h ATR away to survive Asia-session noise and gives roughly 2:1 reward against the 1.3230 objective.

HOLD^CAC

Price 8406.06 remains above the 8380 stop (0.31% distance, 0.95x 1h ATR) and above 1h SMA20/50 (8376.29/8373.88) and daily SMA50/200 (8309.32/8179.21); thesis intact at +80.26 unrealized. VIX at 18.67 (session +5.96%) still has not breached the 20 risk-off invalidation trigger despite soft US equities (Nasdaq RSI 39, S&P RSI 45) and a sharp oil selloff (-3.2% session). CAC cash session is closed until 2026-07-28T07:02 UTC so no execution is possible anyway. Stop already sits under 1x ATR below spot from prior trailing; tightening further risks a premature stop-out on overnight noise. Keeping stop 8380 / target 8550 unchanged.

HOLDEURUSD

Price 1.1378 remains below both 1h SMA20/50 (1.13870/1.13866) and well below daily SMA50/200 (1.14019/1.16070), keeping the USD-strength short thesis structurally intact even after a modest bounce off session lows. Stop at 1.1389 still has ~1.35x 1h ATR of room and open risk is only 0.034% of capital (well within the 1% per-trade cap). VIX at 18.67 has not breached the 20 risk-off confirmation level and 1h RSI (44.91) is neutral, leaving room for continuation toward 1.1330 without an invalidation trigger firing. No change to stop 1.1389 / target 1.1330.

HOLD^CAC

Price 8406.06 stays above the 8380 stop (0.31% distance, ~0.95x 1h ATR) and above 1h SMA20/50 (8376.29/8373.88) and daily SMA50/200 (8309.32/8179.21); thesis intact at +80.26 unrealized. VIX at 18.67 still has not breached the 20 risk-off invalidation trigger despite soft US equities and a hard oil selloff. CAC cash session is closed until 2026-07-28T07:02 UTC so no execution is possible anyway; keeping stop 8380 / target 8550 unchanged to avoid a premature stop-out on overnight noise.

HOLDEURUSD

Price 1.1373 remains below 1h SMA20/50 (1.13884/1.13867) and well below daily SMA50/200 (1.14019/1.16070), keeping the USD-strength short thesis structurally intact. Stop at 1.1389 still has ~1.95x 1h ATR of room and open risk is only 0.034% of capital. 1h RSI (40.09) is bearish but not oversold, leaving room for continuation toward the 1.1330 target. No change to stop 1.1389 / target 1.1330.

HOLD^CAC

Price 8406.06 remains above the 8380 stop (0.31% distance, 0.95x 1h ATR) and above 1h SMA20/50 (8376.29/8373.88) and daily SMA50/200 (8309.32/8179.21); thesis intact at +80.26 unrealized. VIX at 18.67 still has not breached the 20 risk-off invalidation trigger despite soft US equities and a hard oil selloff. CAC cash session is closed until 2026-07-28T07:02 UTC so no execution is possible anyway, and the stop already sits under 1x ATR below spot from prior trailing - tightening further risks a premature stop-out on overnight noise.

Price 1.1373 remains below 1h SMA20/50 (1.13903/1.13868) and well below daily SMA50/200 (1.14812/1.16294), keeping the USD-strength short thesis structurally intact. Stop at 1.1389 still has 1.88x 1h ATR of room and open risk is only 0.034% of capital. 1h RSI (37.55) is bearish but not yet oversold, leaving room for continuation toward the 1.1330 target without hitting the 1.1389 invalidation. No change to stop 1.1389 / target 1.1330.

HOLD^CAC

Price 8406.06 stays above the 8380 stop (0.31% distance, 0.95x 1h ATR) and above 1h SMA20/50 (8376.29/8373.88) and daily SMA50/200 (8309.32/8179.21); thesis intact at +80.26 unrealized.

HOLDEURUSD

Price 1.1375 remains below 1h SMA20/50 (1.13905/1.13869) and well below daily SMA50/200 (1.14812/1.16294), keeping the USD-strength short thesis structurally intact. Stop at 1.1389 still has 1.48x 1h ATR of room and open risk is only 0.034% of capital. The risk-off backdrop (soft Nasdaq/S&P, oil down ~8% 24h, VIX +5.96% to 18.67) persists but hasn't accelerated further this cycle, and 1h RSI (41.8) has ticked up off its low without threatening the invalidation level (close above 1.1389). No change to stop 1.1389 / target 1.1330.
