Affaiblissement marqué du dollar et impulsion haussière des principales devises européennes, accompagné d’une baisse des rendements américains et de la volatilité. Toutefois, EURUSD est extrêmement suracheté à court terme après une forte accélération, tandis que GBPUSD a déjà reflué depuis son sommet intrajournalier. Les indices sont fermés et les autres marchés ouverts ne sont pas négociables en simulation.

HOLDEURUSD

EURUSD has slipped below its 20-hour and 50-hour averages, but it remains above the 50-day and 200-day averages and above the 1.1492 invalidation stop. The broader bullish structure is weakened but not yet invalidated, so the existing defined-risk position remains defensible without modification.

HOLD^SPX

Hold unchanged. SPX remains above entry, its 7418 stop, and its 20-hour, 50-hour, 50-day and 200-day averages, while low VIX supports the bullish continuation thesis. Resistance around 7512-7526, elevated yields and Nasdaq underperformance limit conviction. The US session is closed and SPX data are stale_market_closed, so no execution change is justified.

HOLDEURUSD

Hold unchanged. EURUSD remains above its 50-hour, 50-day and 200-day averages with positive 7-day momentum and is comfortably above the 1.1492 stop. Price is marginally below its 20-hour average, but this does not invalidate the broader bullish structure. High-impact US ISM data in about 58 minutes and an active blackout argue against adding exposure or tightening the stop before the release.

HOLD^SPX

Hold unchanged. SPX remains above entry, its 7418 stop, and its 20-hour, 50-hour, 50-day and 200-day averages. Positive 24-hour momentum and low VIX preserve the bullish continuation thesis, though resistance around 7512-7526, elevated yields and Nasdaq underperformance constrain conviction. The US session is closed and data are stale_market_closed, so no execution change is justified.

HOLDEURUSD

Hold unchanged. EURUSD has recovered above its 20-hour average and remains above its 50-hour, 50-day and 200-day averages, with positive 7-day momentum and constructive hourly and daily RSI. Price remains comfortably above the 1.1492 invalidation stop. High-impact US ISM data in about 118 minutes argues against adding exposure or tightening the stop prematurely but does not invalidate the long thesis.

HOLD^SPX

Hold unchanged. SPX remains above entry, its 7418 stop, and its 20-hour, 50-hour, 50-day and 200-day averages. Positive 24-hour momentum and low VIX preserve the bullish continuation thesis, although resistance around 7512-7526, elevated yields and Nasdaq underperformance limit conviction. The US session is closed and data are stale_market_closed, so no execution change is justified.

HOLDEURUSD

Hold unchanged. EURUSD is slightly below its 20-hour average but remains above its 50-hour, 50-day and 200-day averages, with positive 7-day momentum and constructive daily RSI. Price remains comfortably above the 1.1492 invalidation stop. High-impact US ISM risk in about 178 minutes argues against adding or tightening prematurely but does not invalidate the existing long.

HOLD^SPX

Hold unchanged. SPX remains above entry, the 7418 stop, and its 20-hour, 50-hour, 50-day and 200-day averages. Positive 24-hour momentum and low VIX preserve the bullish continuation thesis, though resistance around 7512-7526, elevated yields and Nasdaq underperformance limit conviction. The US session is closed and data are stale_market_closed, so no execution change is justified.

HOLDEURUSD

Hold unchanged. EURUSD is only marginally below its 20-hour average and remains above its 50-hour, 50-day and 200-day averages, with positive 7-day momentum and constructive daily RSI. Price remains comfortably above the 1.1492 invalidation stop. Upcoming high-impact US ISM data argues against adding or tightening prematurely but does not invalidate the existing long.

HOLD^SPX

Hold unchanged. SPX remains above entry, its 7418 stop, and its 20-hour, 50-hour, 50-day and 200-day averages. Positive 24-hour momentum and low VIX preserve the bullish thesis, though resistance around 7512-7526, elevated yields and Nasdaq underperformance limit conviction. The US session is closed and data are stale_market_closed, so there is no defensible basis for an execution change.

HOLDEURUSD

Hold unchanged. Fresh open-session data show EURUSD marginally above its 20-hour average and clearly above its 50-hour, 50-day and 200-day averages, with positive 7-day momentum and constructive daily RSI. The pullback remains well above the 1.1492 stop. Upcoming high-impact US ISM data argues against adding exposure but does not invalidate the existing long.

HOLD^SPX

Hold unchanged. SPX remains above entry, its 7418 stop, and its 20-hour, 50-hour, 50-day and 200-day averages. Positive 24-hour momentum and low VIX preserve the bullish thesis, while resistance near 7512-7526, elevated yields and Nasdaq underperformance warrant caution. The US session is closed and the market data are stale_market_closed, so there is no defensible basis for an update or close.

Journée de repricing dollar franche et cohérente : l'or bondit de 3,85 % à 4 567,8 (RSI 1h à 81,4), le 10 ans US perd 5,3 pb à 4,653, et le billet vert recule contre tout le bloc — EUR/USD +0,90 % à 1,1681, GBP/USD +0,56 % à 1,3608, USD/JPY -0,94 % à 158,15 avec un RSI 1h à 23. Le signal macro est réel et confirmé par trois familles d'actifs indépendantes, pas par un seul instrument. Côté actions, le tableau est autre : Nasdaq 100 -0,52 % et sous ses SMA 20/50 horaires, S&P 500 -0,10 %, CAC -0,25 % avec un RSI 1h à 26,8, DAX -0,21 %, tous en repli sur sept jours. Le VIX retombe pourtant à 15,02 (-5,65 %), donc pas de stress : ce n'est pas une fuite vers la sécurité, c'est une vente de dollar et une rotation. Le problème du moment n'est pas la lecture du régime, c'est le point d'entrée. Les deux seuls instruments éligibles à l'ouverture (EUR/USD et GBP/USD) sont les deux jambes du même pari sur le dollar, et tous deux se traitent à l'extrême haut de leur journée : l'EUR/USD a parcouru environ 104 pips depuis 1,157943 contre un ATR journalier de 19,4, soit 5,4 fois sa respiration normale, avec un RSI horaire à 82,8. Acheter maintenant, c'est acheter le plus haut du jour au moment où la séance de New York se ferme.

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.

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.
