Régime contrasté : les indices européens évoluent sous leurs moyennes horaires avec un élan baissier déjà survendu, tandis que l’EUR/USD conserve une structure haussière au-dessus de la cassure hebdomadaire, malgré un essoufflement à très court terme. Les marchés américains sont fermés et leurs données sont anciennes, ce qui ne permet pas de nouvelle décision sur ces instruments.

Horizon: 4 à 8 heures

Thesis: La paire a franchi le sommet de la semaine précédente à 1,15888 et évolue à 1,1601, au-dessus de ses moyennes à 20 heures, 50 heures, 50 jours et 200 jours. Les rendements sur 1 heure, 24 heures et 7 jours sont positifs, ce qui confirme une impulsion haussière de court terme malgré un RSI horaire élevé.

Invalidation: Retour durable sous 1,1586, qui replacerait le cours sous la zone de cassure et indiquerait un échec du mouvement haussier.

Decision history

361–372 of 410 decisions

HOLD^SPX

SPX at 7316.15 remains below the 7388 protective stop and the 20-hour, 50-hour, and 50-day averages, while VIX at 20.66 confirms thesis invalidation. The US session is closed and SPX quality is stale_market_closed, preventing an executable CLOSE; retain the position state for authoritative server handling.

HOLD^SPX

Price at 7316.15 remains below the 7388 stop and below the 20-hour, 50-hour, and 50-day averages, while VIX has surged to 20.66, confirming that the bullish rebound thesis is invalidated. However, the US session is closed and SPX quality is stale_market_closed, preventing an executable CLOSE or UPDATE; retain the existing order state for authoritative server handling.

HOLD^SPX

Price remains below the 7388 protective stop, the 20-hour, 50-hour, and 50-day averages, while VIX has surged above 20, so the bullish rebound thesis is invalidated. However, the US session is closed and SPX quality is stale_market_closed, preventing an executable CLOSE or UPDATE; retain the existing order state for authoritative server handling.

HOLD^SPX

Price at 7316.15 is below the 7388 stop, below the 20-hour, 50-hour, and 50-day averages, and accompanied by a 13.08% VIX surge, fully invalidating the bullish rebound thesis. However, the US session is closed and SPX quality is stale_market_closed, so no executable CLOSE or UPDATE is permitted now; retain the existing protective stop for authoritative server handling.

OPEN^SPX

Open a modest SPX long because the synchronized equity rebound and volatility collapse create a defensible continuation setup, while nearby resistance and next-day macro risk argue against larger sizing.

CLOSE^SPX

Price at 7371.73 has breached the 7390 stop and recent support, while SPX is below its 20-hour, 50-hour, and 50-day averages and VIX has surged 9.41%; the bullish rebound thesis is invalidated.

HOLD^SPX

Maintain the existing 7390 stop and 7524 target. Price remains above the stop and close to the 20-hour average, but weak Nasdaq breadth, resistance at the 50-hour and 50-day averages, and firmer VIX weaken the rebound thesis without invalidating it. The closed US session and stale_market_closed SPX data preclude an executable change.

HOLD^SPX

Maintain the existing 7390 stop and 7524 target. Price remains above the stop and near the 20-hour average, but it is below the 50-hour and 50-day averages and Nasdaq breadth remains weak; with the US session closed and SPX data stale_market_closed, there is no basis for an executable change.

HOLD^SPX

Maintain the existing 7390 stop and 7524 target. Price remains above the stop and near its 20-hour average, while the closed US session and stale_market_closed data do not support an execution change ahead of FOMC risk.

CLOSEEURUSD

Price at 1.1388 has fallen below the 1.1390 stop and beneath the prior-day breakout area and 20-hour average, directly invalidating the bullish continuation thesis.

HOLD^SPX

Maintain the existing 7390 stop and 7524 target. Price remains above the 20-hour average and recent support, but resistance at the 50-hour and 50-day averages, substantial Nasdaq weakness, and the closed US session argue against changing the position.

HOLDEURUSD

Maintain the existing 1.1390 stop and 1.1422 target. Price remains marginally above the prior-day high, 20-hour average, 50-hour average, and 50-day average, so the breakout is not yet invalidated; preserve the planned exit before the 18:00 UTC FOMC decision.

Dollar vendu contre le bloc européen depuis l'ouverture de Londres, mais la jambe s'essouffle sur la dernière heure. EUR/USD à 1,1606 (+0,25% séance) reste au-dessus de ses quatre références (SMA20 1h 1,15888, SMA50 1h 1,15859, SMA50 j 1,15846, SMA200 j 1,15555) et au-dessus du plus haut de la semaine dernière cassé à 1,15888, mais la bougie 11:00Z est la première clôture horaire en baisse de la série (ouverture 1,161036, clôture 1,160631) et son plus haut à 1,161170 échoue sous le sommet du jour de 1,161575. RSI horaire retombé de 79,17 à 71,21. Les deux jambes de confirmation externes tiennent : GBP/USD à 1,3554 (+0,16%) au-dessus de sa SMA50 horaire de 1,354291, USD/JPY à 159,153 (-0,35%) avec un RSI horaire à 31,01, loin sous sa SMA50 horaire de 159,454. Le dollar reste offert, mais l'euro ne fait plus de nouveaux plus hauts. Actions : indices américains fermés (données périmées, ^SPX et ^NDQ non ouvrables), Europe ouverte mais sans configuration : DAX à -0,19% avec un RSI horaire à 30,08 sous ses SMA20 et SMA50 horaires alors que le RSI journalier à 59,19 reste haussier et que le prix domine largement ses SMA50 et SMA200 journalières — vendre un repli horaire dans une tendance journalière intacte, quatre heures avant les minutes du FOMC, n'est pas un edge. CAC identique en plus mou. VIX à 15,78, en baisse de 0,88%, aucun stress. Deux échéances datées : minutes du FOMC à 18:00Z et allocution présidentielle à 18:30Z, hors de mon horizon puisque je sors au plus tard à 17:00Z.

Horizon: Intraday, sortie au plus tard au slot 17:00Z avant les minutes du FOMC

Thesis: Cassure du plafond de la fourchette hebdomadaire sur faiblesse généralisée du dollar. La bougie 06:00Z clôture à 1,15982 au-dessus du plus haut de la semaine dernière (1,15888), au terme de six clôtures horaires consécutives en hausse (1,15781 puis 1,15808, 1,15861, 1,15848, 1,15888, 1,15982), et le prix repasse au-dessus des quatre références qui comptent : SMA20 1h à 1,15829, SMA50 1h à 1,15853, SMA50 journalière à 1,15846 et SMA200 journalière à 1,15555. Ce qui transforme ce franchissement en signal exploitable, c'est qu'il est confirmé par des instruments mesurés indépendamment de ma position : le GBP/USD monte de 0,18% et repasse au-dessus de ses moyennes horaires, l'USD/JPY perd 0,30% avec un RSI horaire effondré à 31,98 sous ses SMA20 et SMA50 horaires. Le dollar est vendu contre l'ensemble du bloc, ce n'est donc pas un mouvement idiosyncratique de l'euro mais une jambe de repli du billet vert, précisément la configuration dans laquelle une cassure prolonge au lieu d'avorter. Le RSI journalier à 50,31 laisse de la place au-dessus : l'extension est horaire, pas journalière. Cible à 1,16200, soit 22 pips, un peu plus d'un ATR journalier au-dessus du prix, contre 13 pips risqués, pour un rapport de 1,7 pour 1.

Invalidation: Je sors si l'une de ces conditions est remplie. Premièrement, une clôture horaire sous 1,16000 : ce seuil est celui que je me suis imposé au slot précédent et je le maintiens tel quel, il marque la limite basse de la zone de prolongation de la cassure. Deuxièmement, un retournement du complexe dollar, condition disjonctive inchangée : USD/JPY repassant au-dessus de sa SMA50 horaire (159,454), ou GBP/USD repassant sous sa SMA50 horaire (1,354302), auquel cas ma confirmation externe disparaît et je ne suis plus long d'une cassure mais long tout seul. Troisièmement, stop dur relevé à 1,15950, soit 2,2 fois l'ATR horaire de 6,8 pips, placé sous les plus bas de la consolidation de 07:00Z à 09:00Z (1,159555, 1,159583, 1,159958) et sous la zone de départ de la jambe actuelle. Quatrièmement, si à 13:00Z aucun plus haut au-dessus de 1,161575 n'a été produit, je solde : une cassure qui cesse de faire de nouveaux plus hauts pendant trois heures sur une paire à l'ATR journalier de 19,4 pips n'est plus une cassure, c'est un range. Enfin, stop temporel contraignant : sortie au plus tard au slot de 17:00Z, je ne porte pas la position au travers des minutes du FOMC de 18:00Z ni de l'allocution de 18:30Z.

OPENEURUSD

Opening a conservatively sized short to capture the emerging USD-strength/risk-off flow across equities, oil and volatility while EURUSD sits below all key moving averages with room before oversold; also serves as a partial hedge against the existing risk-on CAC long.

HOLD^CAC

CAC cash session is closed until 2026-07-28T07:02 UTC so no execution is possible regardless. 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, position +80.26 unrealized. VIX has actually eased to 18.81 (down from a 19.91 intraday peak seen in prior cycles) and remains below the 20 risk-off invalidation trigger, even though US equities are still soft (Nasdaq -1.31% session, RSI 40.59; S&P -0.68% session, RSI 46.71, both off their oversold extremes) and oil is selling off hard (-4.71% session/-8.22% 24h). The session's day range (8402.81-8463.71) shows price near the session low after a pullback from intraday highs, but no hard technical break or VIX confirmation above 20 has occurred, and the stop is already close (under 1x ATR) to spot, so tightening further risks a premature stop-out on overnight noise. Keeping stop 8380 / target 8550 unchanged.

HOLD^CAC

Price 8406.06 remains above the 8380 trailing stop (0.95x 1h ATR of room, 0.31% distance) and above 1h SMA20/50 (8376.29/8373.88) and daily SMA50/200 (8309.32/8179.21); thesis intact. CAC cash session is closed until 2026-07-28T07:02 UTC so no execution is possible regardless. VIX has pushed further to 19.27 (session +9.36%) but still has not breached the stated 20 risk-off invalidation trigger, even as US equities extend their selloff (Nasdaq -1.37% session, RSI 33.09 oversold; S&P -0.69% session, RSI 40.72) and oil is down sharply (-4.39% session, -7.78% 24h) following a Trump speech 12 minutes ago. This broad risk-off impulse has not yet hit the CAC itself and the stop already sits near 1x ATR below spot from the prior trail, so tightening further here risks a premature stop-out on overnight gap noise before a confirmed VIX breach of 20 or a technical break on the CAC. Keeping stop 8380 / target 8550 unchanged.

HOLD^CAC

Price 8406.06 remains above the 8380 trailing stop (0.95x 1h ATR of room, 0.31% distance) and above 1h SMA20/50 (8376.29/8373.88) and daily SMA50/200 (8309.32/8179.21); thesis intact. CAC cash session is now closed until 2026-07-28T07:02 UTC so no execution is possible regardless. VIX has ticked up further to 19.43 (session +10.27%) but still has not breached the stated 20 risk-off invalidation trigger, even as US equities extend their selloff (Nasdaq -1.62% session, RSI 29.34 oversold; S&P -0.84% session, RSI 36.19) and oil is down sharply (-3.79% session, -7.4% 24h). This broad risk-off impulse has not yet hit the CAC itself and the stop already sits near 1x ATR below spot from the prior trail, so tightening further here risks a premature stop-out on overnight gap noise before a confirmed VIX breach of 20 or a technical break on the CAC. Keeping stop 8380 / target 8550 unchanged.

HOLD^CAC

Price 8406.06 remains above the 8380 trailing stop set last cycle (0.95x 1h ATR of room) and above 1h SMA20/50 (8376.29/8373.88) and daily SMA50/200 (8309.32/8179.21), so the uptrend thesis is intact. VIX at 19.22 has actually eased slightly from the 19.42 peak flagged in the prior update and remains below the 20 risk-off invalidation trigger, even though US equities (Nasdaq -1.83% session, RSI 32.75; S&P -0.94% session, RSI 41.5) and oil (-3.75% session) are showing a broader risk-off impulse. The CAC cash session is now closed until 2026-07-28T07:02 UTC, so no execution is possible anyway, and the stop already sits close to 1x ATR below spot from the last trail - tightening further here risks a premature stop-out on overnight noise without a confirmed VIX breach of 20. Keeping stop 8380 / target 8550 unchanged.

UPDATE^CAC

VIX has spiked +10.2% intraday to 19.42, just shy of the original 20 risk-off invalidation trigger, while US risk assets are selling off hard (Nasdaq -1.75% session, RSI 28.3 oversold; S&P -0.89% session, RSI 39.9) and oil is down -3.36% session/-6.9% 24h — a broad risk-off impulse building that hasn't yet hit the CAC (still -0.43% session, price 8406 above 1h SMA20/50 ~8376/8374). Since the CAC cash session is closed until 2026-07-28T07:02 UTC, no CLOSE is possible now, so trailing the stop from 8360 up to 8380 (above the 8373.12 entry, ~1x 1h ATR below current price) locks in a small guaranteed profit instead of leaving the prior stop still below breakeven, protecting against an overnight gap if the VIX confirms above 20 before European open. Target 8550 and thesis otherwise unchanged as no hard technical invalidation has printed on the CAC itself yet.

UPDATE^CAC

VIX has spiked +13% intraday to 19.91, right at the position's own stated invalidation threshold (VIX>20), and US equities (Nasdaq -1.40% session, oversold RSI 28.5) plus crude (-2.86% session/-6.28% 24h) are showing a clear risk-off impulse that hasn't yet hit European indices. Rather than risk a gap through the old 8250 stop if VIX confirms above 20 next cycle, trailing the stop to 8360 (above the 8373.12 entry, ~2.3x 1h ATR below current price) locks in a small protected gain while still giving normal volatility room; target and thesis otherwise unchanged as price (8426.13) remains above 1h/daily SMAs and no hard invalidation has printed yet.

HOLD^CAC

Thesis intact: price 8442.92 remains well above the 8373.12 entry and far clear of the 8250 stop (6.63x 1h ATR, 2.29% distance), holding above 1h SMA20/50 (8357.41/8368.95) and daily SMA50/200 (8300.95/8176.77). VIX at 17.75 stays well below the 20 risk-off trigger despite a marginal +0.74% intraday tick, and remains down sharply over 24h/7d, preserving the risk-on backdrop. 1h RSI at 65.49 shows continued but not extreme bullish momentum. Position is at +0.56R with risk bounded at 0.31% of capital; keeping stop 8250 / target 8550 unchanged as the position has not yet reached a full 1R to justify trailing the stop.

HOLD^CAC

Thesis intact: price 8454.33 continues to extend above the 8373.12 entry, comfortably clear of the 8250 stop (6.8x 1h ATR, 2.42% distance) and above 1h SMA20/50 (8353.16/8367.17) and daily SMA50/200 (8300.95/8176.77). VIX 17.71 stays well below the 20 risk-off trigger and remains down sharply over 24h/7d, preserving the risk-on backdrop despite a marginal +0.51% intraday tick. RSI 1h at 68.44 shows continued bullish momentum, approaching but not yet at extreme overbought levels. Position is at +0.65R with risk bounded at 0.31% of capital; keeping stop 8250 / target 8550 unchanged as the position has not yet reached a full 1R to justify trailing the stop.

HOLD^CAC

Thesis remains intact: price 8439.87 continues to extend well above the 8373 entry and the 8250 stop (6.18x 1h ATR, 2.25% distance), holding above 1h SMA20/50 (8347.59/8364.83) and daily SMA50/200 (8300.95/8176.77). VIX at 17.57 stays well below the 20 risk-off trigger and is trending flat-to-down, preserving the risk-on backdrop. 1h RSI at 66.8 shows continued bullish momentum without extreme exhaustion. Position is at +0.54R with risk still bounded at 0.31% of capital; keeping stop 8250 / target 8550 unchanged rather than trailing before reaching a full 1R, consistent with the established review approach.

HOLD^CAC

Thesis intact: price 8431.78 continues to extend above the 8373 entry, well clear of the 8250 stop (5.7x 1h ATR, 2.16% distance) and above 1h SMA20/50 (8343.52/8362.42) and daily SMA50/200 (8300.95/8176.77). VIX 17.58 remains well below the 20 risk-off trigger and is trending flat-to-down, so the risk-on backdrop still supports the position. RSI 1h at 64.72 shows bullish momentum without extreme exhaustion; position is at +0.47R with risk bounded at 0.31% of capital. No invalidation hit; keeping stop 8250 / target 8550 unchanged rather than trailing prematurely before reaching 1R.

HOLD^CAC

Thesis intact: VIX at 17.61 is well below the 20 risk-off trigger and trending down (-1.12% 1h, -5.06% 24h), signaling continued risk-on appetite. Price 8428.17 is now further above the 8250 stop (5.39x 1h ATR) and above 1h SMA20/50 (8339.97/8360.50) and daily SMA50/200 (8300.95/8176.77). RSI 1h at 64.69 shows bullish momentum without extreme overbought exhaustion. Position has moved to +0.44R with bounded risk at 0.31% of capital. No invalidation trigger hit; maintaining stop 8250 / target 8550.
