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

EURUSD remains below its 20-hour, 50-hour and 50-day averages, hourly RSI is mildly bearish at 41.94, and price remains well below the 1.1562 invalidation. Downside momentum is limited and US yields softened, but the 1.1520 target remains plausible within the active 1-3 day horizon. Hold unchanged with minimal defined risk and do not add ahead of US CPI.

HOLDEURUSD

The short remains below its 1.1562 invalidation and below the 20-hour, 50-hour and 50-day averages, while hourly RSI at 44.17 retains a mild bearish bias. Softer US yields and nearly flat 24-hour price action limit conviction, but the position remains within its 1-3 day horizon with minimal defined risk. Hold unchanged and do not add ahead of US CPI.

HOLDEURUSD

The short remains below the 1.1562 invalidation and marginally below its 20-hour, 50-hour and 50-day averages, so the thesis is not yet broken. Hourly RSI at 46.45 and softer US yields show limited downside momentum, but the position remains within its 1-3 day horizon with minimal defined risk. Hold unchanged and do not add ahead of US CPI.

HOLDEURUSD

The short remains below its 1.1562 invalidation and marginally below the 50-hour and 50-day averages, so the thesis is not broken. Price above the 20-hour average, neutral RSI, nearly flat 24-hour movement, and slightly lower US yields show weak downside momentum. Hold unchanged with minimal defined risk, but do not add before US CPI.

HOLDEURUSD

The short remains below its 1.1562 invalidation and marginally below the 50-hour and 50-day averages, so it is not technically broken. However, price is above the 20-hour average, hourly RSI is neutral, and US yields eased over 24 hours, indicating weak downside follow-through. Hold unchanged given minimal defined risk, but do not add ahead of US CPI.

HOLDEURUSD

The short thesis remains marginally valid because EURUSD is below its 50-hour and 50-day averages and has not breached 1.1562. However, neutral hourly RSI, flat 24-hour performance, and price above the 20-hour average show weak follow-through. Hold unchanged given minimal defined risk, but do not add before US CPI.

HOLDEURUSD

EURUSD remains below its 50-hour and 50-day averages and has not breached the 1.1562 invalidation, so the short thesis is still technically valid. However, price is above its 20-hour average, hourly RSI is neutral at 51.36, and US yields eased, showing weak downside follow-through. Hold unchanged because defined risk is minimal and the 1-3 day horizon remains active, but do not add ahead of US CPI.

HOLDEURUSD

The short has weakened because EURUSD is now above its 20-hour average, hourly RSI is neutral at 51.36, and US yields have eased. Still, price remains marginally below its 50-hour and 50-day averages and well below the 1.1562 invalidation. With minimal defined risk and the 1-3 day horizon still active, hold unchanged but do not add ahead of US CPI.

HOLDEURUSD

EURUSD remains below its 50-hour and 50-day averages and below the 1.1562 invalidation, so the short thesis is not broken. However, price is marginally above its 20-hour average, hourly RSI is neutral at 47.09, and US yields are down slightly over 24 hours, indicating limited downside momentum. Retain the position unchanged because stop-defined risk is minimal, but do not add ahead of US CPI.

HOLDEURUSD

EURUSD remains below its 20-hour, 50-hour and 50-day averages, with hourly RSI at 42.4 and price still below the 1.1562 invalidation. The 1.1520 target remains plausible within the active 1-3 day horizon, although easing US yields and weak downside momentum reduce conviction. Hold unchanged with minimal stop-defined risk and do not add ahead of US CPI.

HOLDEURUSD

EURUSD remains below its 20-hour, 50-hour and 50-day averages, with hourly RSI at 46.2 and price still below the 1.1562 invalidation. Downside momentum is modest and US yields are not strengthening materially, but the 1.1520 target remains plausible within the 1-3 day horizon and stop-defined risk is minimal. Hold unchanged without adding ahead of US CPI.

HOLDEURUSD

EURUSD is slightly above its 20-hour average and hourly RSI is neutral, confirming weak downside momentum. However, it remains below the 50-hour and 50-day averages and below the 1.1562 invalidation, while the position has minimal stop-defined risk and remains within its 1-3 day horizon. Hold unchanged, but avoid adding exposure ahead of tomorrow's US CPI releases.

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.
