Affaiblissement marqué du dollar face à l’euro et à la livre, mais mouvements déjà étendus et proches du surachat, surtout sur EURUSD. Les marchés actions sont fermés et leurs données ne sont pas admissibles à une nouvelle ouverture. Aucun point d’entrée actuel n’offre un rapport rendement-risque suffisamment robuste.

The long thesis remains intact: SPX is above entry and its 20-hour, 50-hour, 50-day and 200-day averages, with positive 24-hour momentum and a low, falling VIX. Price remains above the 7418 invalidation and stop risk is bounded. Hold unchanged because nearby 7512-7526 resistance, elevated yields, Nasdaq underperformance, weekend gap risk, the closed session and stale closed-market data do not justify changing exposure.

Journée de dépréciation généralisée du dollar, confirmée par quatre instruments indépendants les uns des autres : or +4,218% sur 24h (mouvement énorme, 4571,8 contre une SMA200 journalière à 4464,6), 10 ans US à 4,653% soit -5,3 pb, USD/JPY -0,809% avec un RSI journalier à 29,21 en rupture franche, EUR/USD +0,853% et GBP/USD +0,476%. Le VIX recule de 6,47% à 14,89, donc ce n'est pas un choc d'aversion au risque : c'est une repricing du dollar et des taux, les actions ne baissant que marginalement (S&P 500 -0,11%, Nasdaq 100 -0,52%). Les indices européens sont en revanche nettement plus faibles sur la semaine (CAC -1,99% sur 7 jours, cinquième séance de repli, RSI 1h à 26,83) mais ils sont fermés et leurs données ont 8 heures de retard : hors champ. Sur le change, l'EUR/USD est le véhicule le plus tendu du mouvement — RSI 1h à 78,72 et RSI journalier à 76,83, environ 109 pips parcourus depuis 1,1577 soit près de deux ATR journaliers (0,00557) — et il consolide depuis cinq heures dans une fourchette de 10 pips au contact de ses plus hauts, sans rendre un pip. Le GBP/USD raconte la même histoire avec un retard : cassure nette de son plus haut hebdomadaire (1,35615), pointe à 1,36294, repli contenu à 1,35908, puis stabilisation au-dessus de sa SMA20 horaire (1,35842), avec un RSI horaire à 61,93 seulement. Session asiatique, liquidité fine, aucun événement macro avant 12:30Z.

Horizon: Intraday, gestion slot par slot, sortie au plus tard vers 16:00Z le 20/08

Thesis: Je joue la continuation de la faiblesse du dollar sur le seul instrument éligible dont l'entrée n'est pas située à l'extrême du mouvement. Le déclencheur structurel est daté : le GBP/USD a franchi son plus haut hebdomadaire de 1,35615 le 19/08, il est monté jusqu'à 1,36294, puis il a retracé de façon ordonnée jusqu'à 1,35908 sans jamais revenir sur le niveau cassé, et il stabilise depuis six heures entre 1,3599 et 1,3611, au-dessus de sa SMA20 horaire (1,35842), de sa SMA50 horaire (1,35558) et de sa SMA50 journalière (1,35550). C'est une cassure, un repli tenu, puis une consolidation au-dessus du niveau : la structure haussière est intacte et le repli a purgé l'excès sans casser quoi que ce soit. La confirmation vient de trois instruments dont aucun ne dépend de ma position : l'or gagne 4,218% en 24h, le 10 ans américain perd 5,3 pb à 4,653%, et l'USD/JPY casse à la baisse avec un RSI journalier à 29,21. Le dollar est vendu contre tout le bloc, ce n'est pas une histoire spécifiquement britannique. Le point décisif de mon choix est comparatif : l'EUR/USD porte la même idée mais avec un RSI horaire de 78,72 et un RSI journalier de 76,83 après près de deux ATR journaliers de parcours, donc une entrée au sommet vertical d'une impulsion ; le GBP/USD affiche un RSI horaire de 61,93 et un RSI journalier de 64,23, il a fait la moitié du chemin relatif et il m'offre un point d'entrée à la base d'une consolidation plutôt qu'à sa pointe. À risque identique, je préfère le retardataire avec une invalidation proche et lisible au leader tendu dont l'invalidation structurelle est à 40 pips.

Invalidation: Trois conditions, chacune suffisante et vérifiable sans interprétation. Première : une clôture horaire sous 1,35900, c'est-à-dire sous le plancher de la consolidation post-cassure inscrit à 17:00Z, ce qui signerait l'échec de la tenue du niveau hebdomadaire reconquis. Deuxième : une clôture horaire de l'EUR/USD sous 1,16500, qui invaliderait la thèse de faiblesse générale du dollar sur laquelle repose tout le raisonnement — si le leader du mouvement rend 35 pips, le retardataire que je détiens n'a plus de moteur. Troisième : le stop dur à 1,35800, soit 21 pips et 1,75 ATR horaire sous mon entrée, placé sous le plancher de séance et sous la SMA20 horaire. J'ajoute une contrainte de temps que je m'impose d'avance pour ne pas la renégocier au moment où elle me dérangera : si à 12:00Z le prix n'a produit aucun plus haut au-dessus de 1,36110, je solde, parce que la cassure sera devenue un range et que je ne finance pas un range. Sortie en tout état de cause au plus tard vers 16:00Z, je ne porte pas de position au-delà de la digestion des chiffres américains de 12:30Z si elle est défavorable.

HOLDEURUSD

Structure still supports the short: 1.1380 remains below 1h SMA20/50 (1.13823/1.13864) and far below daily SMA50/200 (1.14019/1.16070), with daily RSI at 40 and 24h -0.25%. The Asia-session grind higher is shallow (1h RSI 47.86 is neutral, not a reversal) and price has not reclaimed the 1.1389 invalidation, which still sits 1.1x 1h ATR away with risk at stop of only 0.034% of capital. Cross-asset USD support persists via oil -5.57% 24h and gold -1.24% 24h. No change to stop 1.1389 / target 1.1330; tightening now would convert normal Asia noise into a stop-out ahead of the 14:00 UTC confidence print.

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.

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.

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.

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.
