Régime intrajournalier instable et fortement influencé par l’affaiblissement du dollar : EURUSD et GBPUSD progressent nettement mais sont déjà surachetés à l’échelle horaire, tandis que les indices américains divergent et restent sous leurs moyennes horaires courtes malgré le recul du VIX et des taux. Aucun point d’entrée ne présente actuellement un rapport rendement-risque suffisamment robuste.

HOLDEURUSD

Downside momentum remains weak as EURUSD trades above its 20-hour average with neutral hourly RSI, while US yields have eased modestly. However, price is still below the 50-hour and 50-day averages and has not breached the 1.1562 invalidation. With minimal stop-defined risk and the 1-3 day horizon still active, retain the short unchanged.

HOLDEURUSD

EURUSD has reclaimed its 20-hour average and hourly RSI is neutral, so downside momentum has weakened. However, price remains below the 50-hour and 50-day averages and has not breached the 1.1562 invalidation. With the 1-3 day horizon still active and stop-defined risk minimal, retain the position without modification.

HOLDEURUSD

The short thesis has weakened as EURUSD rebounded slightly above its 20-hour average and hourly RSI normalized to 50.59, but price remains below the 50-hour and 50-day averages and has not breached the 1.1562 invalidation. The defined risk remains minimal, so no change is warranted yet.

HOLDEURUSD

EURUSD remains below its 20-hour, 50-hour and 50-day averages, with hourly RSI at 42.13 and firm US yields continuing to support the USD. Price remains well below the 1.1562 invalidation level, while the 1.1520 target is still plausible. Nearby support and limited downside follow-through reduce conviction but do not yet invalidate the short.

HOLDEURUSD

The short thesis remains valid: EURUSD is below its 20-hour, 50-hour and 50-day averages, hourly RSI remains weak at 39.74, and price is still well below the 1.1562 invalidation. Local support and subdued recent movement limit conviction, but the 1.1520 target remains plausible and stop-defined risk is minimal.

HOLDEURUSD

EURUSD remains below its 20-hour, 50-hour and 50-day averages, with hourly RSI at 39.74 and price still well below the 1.1562 invalidation. Elevated US yields continue to provide tactical USD support. Nearby support limits conviction, but the 1.1520 target remains plausible and stop-defined risk is minimal.

HOLDEURUSD

The short remains technically valid: EURUSD trades below its 20-hour, 50-hour and 50-day averages, price remains well below the 1.1562 invalidation, and elevated US yields provide tactical USD support. The latest hourly rebound and nearby support reduce conviction, but the 1.1520 target remains plausible and stop-defined risk is minimal.

HOLDEURUSD

The short remains profitable and technically valid: EURUSD is below its 20-hour, 50-hour and 50-day averages, recent hourly candles show renewed downside momentum, and price remains below the 1.1562 invalidation. Hourly RSI at 33.1 raises rebound risk, but the 1.1520 target remains reachable and stop-defined risk is minimal.

HOLDEURUSD

EURUSD remains below its 20-hour, 50-hour and 50-day averages, with hourly RSI at 42.93 and elevated US yields providing modest USD support. Price remains below the 1.1562 invalidation, and stop-defined risk is minimal, though consolidation limits conviction.

HOLDEURUSD

EURUSD remains below its 20-hour, 50-hour and 50-day averages, with hourly RSI at 44.64 and price still below the 1.1562 invalidation. Consolidation limits conviction, but elevated US yields provide tactical USD support and the existing stop-defined risk remains minimal.

HOLDEURUSD

EURUSD remains below its 20-hour, 50-hour and 50-day averages, with hourly RSI at 44.64 and price still well below the 1.1562 invalidation level. The latest rebound is modest, stop-defined risk remains minimal, and the existing target still offers favorable reward relative to risk.

HOLDEURUSD

Hold without modification. EURUSD remains below its 20-hour, 50-hour and 50-day averages, hourly RSI has weakened to 40.57, and the latest completed hour closed near its low. Price remains below the 1.1562 invalidation level, while stop-defined risk is minimal.

Journée de rupture nette sur le dollar, déclenchée à 12:00Z et corroborée par quatre instruments indépendants : EUR/USD +0,77% à 1,1673, GBP/USD +0,51% à 1,3611, USD/JPY -0,74% à 158,38, or +3,08% à 4552 et 10 ans US en repli de 4,8 pb à 4,66%. Ce n'est pas du bruit de séance, c'est un repricing dollar/taux généralisé, tous les mouvements naissant sur la même bougie horaire. Le VIX recule à 15,17 (-4,7%), donc l'impulsion n'est pas une fuite vers la sécurité : c'est une lecture dovish anticipée. Côté actions, tableau moins lisible : S&P 500 quasi inchangé sur la séance (7716,87) mais sous ses SMA 20 et 50 horaires, Nasdaq 100 à 29470 en baisse de 0,37% et 1% sous sa SMA 50 horaire, tous deux très au-dessus de leurs moyennes journalières — correction dans une tendance haussière intacte, sans direction tranchée à l'échelle du slot. Europe close et donc hors jeu : CAC à 8501,91 clôture pile sur son plus bas du jour après -1,99% en 7 jours, DAX plus résilient. Le fait dominant reste le calendrier : minutes du FOMC dans 57 minutes, blackout actif, suivies d'une allocution présidentielle 30 minutes plus tard. Tout le champ éligible (S&P, Nasdaq, EUR/USD, GBP/USD) est directement exposé à ces deux publications.

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.

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.
