Régime très volatil et discordant immédiatement après les minutes du FOMC : faiblesse intrajournalière des actions américaines, forte appréciation de l’euro et de la livre face au dollar, détente du VIX et des rendements américains, tandis que l’or bondit. Les signaux directionnels sont déjà étendus et peu homogènes.

HOLDEURUSD

Hold unchanged. Fresh open-session data show EURUSD still above its 20-hour, 50-hour, 50-day and 200-day averages, with positive 7-day momentum and constructive hourly and daily RSI. Price remains well above the 1.1492 stop despite a modest move below entry. Upcoming US ISM risk argues against increasing exposure but does not invalidate the existing long.

HOLD^SPX

Hold unchanged. SPX remains above entry, its 7418 stop, and the 20-hour, 50-hour, 50-day and 200-day averages. Positive 24-hour momentum and the low, falling VIX preserve the bullish thesis. Resistance near 7512-7526, elevated yields, Nasdaq underperformance and reopening-gap risk warrant caution, but the closed session and stale market-closed data provide no defensible basis for a change.

HOLDEURUSD

Hold unchanged. Fresh open-session data show EURUSD above its 20-hour, 50-hour, 50-day and 200-day averages, with positive 7-day momentum and constructive hourly and daily RSI. Price remains above entry and the 1.1492 invalidation level. Upcoming US ISM event risk argues against increasing exposure 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 the low, falling VIX preserve the bullish thesis. Resistance near 7512-7526, elevated yields, Nasdaq underperformance and reopening gap risk warrant caution, but the closed session and stale market-closed data provide no defensible basis to alter the position.

HOLDEURUSD

Hold unchanged. Fresh open-session data show EURUSD above its 20-hour, 50-hour, 50-day and 200-day averages, with positive 7-day momentum and constructive hourly and daily RSI. The modest pullback has not broken trend structure, and the 1.1492 stop still defines invalidation. Upcoming US ISM risk argues against increasing exposure but does not justify closing the existing position.

HOLD^SPX

Hold unchanged. SPX remains above entry, the 7418 stop, and its 20-hour, 50-hour, 50-day and 200-day averages, while positive 24-hour momentum and a low, falling VIX preserve the bullish thesis. Nearby resistance, elevated yields, Nasdaq underperformance and upcoming ISM risk warrant caution, but the session is closed and the stale market-closed data do not justify a change.

HOLDEURUSD

Hold unchanged. EURUSD remains above its 20-hour, 50-hour, 50-day and 200-day averages with positive 7-day momentum and constructive hourly and daily RSI. The pullback from the Asian-session high has not broken structure, and the 1.1492 stop continues to define invalidation ahead of upcoming USD event risk.

HOLD^SPX

Hold unchanged. Price remains above entry, the 7418 stop, and the 20-hour, 50-hour, 50-day and 200-day averages. Positive 24-hour momentum and a low, falling VIX preserve the bullish thesis, while the closed session and stale market-closed data provide no defensible basis to update or close.

HOLDEURUSD

Hold unchanged. The small move below entry does not invalidate the setup: EURUSD remains above its 20-hour, 50-hour, 50-day and 200-day averages, with positive 7-day momentum and constructive hourly and daily RSI. The 1.1492 stop continues to define thesis failure.

HOLD^SPX

Hold unchanged. SPX remains above entry, its 7418 invalidation, and the 20-hour, 50-hour, 50-day and 200-day averages; positive 24-hour momentum and a low, falling VIX continue to support the long thesis. Resistance at 7512-7526, elevated yields, Nasdaq underperformance and upcoming ISM risk warrant caution, but the closed session and stale market-closed data do not justify an update or close.

OPENEURUSD

Open a modest EURUSD long because fresh, open-session data show aligned multi-timeframe trend strength after a controlled pullback. Position size and stop imply limited loss relative to capital, while the target offers favorable reward versus defined risk.

HOLD^SPX

Hold unchanged. SPX remains above entry, its 7418 invalidation, and the 20-hour, 50-hour, 50-day and 200-day averages; positive 24-hour momentum and a low, falling VIX continue to support the long thesis. Resistance at 7512-7526, elevated yields, Nasdaq underperformance, reopening gap risk and the upcoming ISM release warrant caution, but closed-session stale data do not justify an update or close.

Régime de repricing dollar, pas de régime directionnel exploitable sur ce que je peux traiter. Le dollar est vendu contre tout le bloc : EUR/USD +0,74% à 1,1662, GBP/USD +0,44% à 1,3592, USD/JPY -0,64% à 158,60, 10 ans US -3,8 pb à 4,67%, et surtout l'or +3,52% à 4546 sur une seule impulsion (bougie 12:00Z, de 4419 à 4496, puis extension). Ce mouvement n'est pas né du FOMC : il est daté de 12:00Z, soit 8h30 heure de New York, et il est déjà entièrement dans les prix que j'ai sous les yeux. Les actions ne valident pas le récit dovish : S&P 500 à 7714,86 quasi inchangé sur la séance et sous ses SMA20 et SMA50 horaires (7735 et 7752), Nasdaq 100 -0,43% à 29 453, sous une SMA20 horaire à 29 749, RSI horaire à 33,97. Or qui explose, obligations qui montent, dollar qui casse, mais indices qui refusent de suivre, avec un VIX en baisse de 4,33% à 15,23 : les compartiments racontent deux histoires différentes, ce qui est la définition d'un marché non lisible. En structure de fond, rien n'est cassé : SPX et NDQ restent très au-dessus de leurs SMA50 et SMA200 journalières, RSI journaliers à 56,6 et 52,8, donc ni tendance épuisée ni retournement établi — juste du bruit intraday sous les moyennes horaires. Les indices européens sont fermés et en données périmées (7336 secondes, statut stale_market_closed) : inéligibles par règle. VIX, 10 ans, WTI, or et USD/JPY ne sont pas négociables en simulation. Le champ éligible se réduit donc à ^SPX, ^NDQ, EUR/USD et GBP/USD.

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. Keeping stop 8380 / target 8550 unchanged.

HOLDEURUSD

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. VIX at 18.67 (session +5.96%) still has not breached the 20 risk-off invalidation trigger despite soft US equities and a hard oil selloff.

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.
