Market Open: Dollar Tests Key FX Levels as Monday Trade Gets Underway — August 17

EUR/USD: 0.8600 Becomes the Line in the Sand

EUR/USD has slipped from a previous 0.86453 reference to 0.8626, a 0.22% decline. That puts 0.8600 within striking distance and makes it the obvious psychological support to watch through the European session and into the US open.

Price action below 0.8620 would keep sellers in control and expose 0.8600. A clean break and failed retest of 0.8600 would strengthen the bearish setup, with 0.8580 the next area to monitor. But don't chase weakness directly into the round number: a rejection from 0.8600 could squeeze price back toward 0.8645, which now acts as the first meaningful resistance reference.

EUR/GBP adds another piece to the picture. It's up 0.06% at 0.8550, suggesting the euro's weakness isn't uniform across crosses. That makes the EUR/USD support reaction more useful than simply assuming broad euro selling.

• •Setup: Watch 0.8600 for a break-and-retest short. If support holds instead, 0.8645 is the first recovery target and resistance test.

USD/JPY: Buyers Push Toward 159.50

USD/JPY is moving the other way, trading at 159.23 versus 159.01 previously. The 159.00 area is now the first intraday pivot, while 159.50 is the immediate upside resistance zone. Above that sits the much bigger 160.00 psychological level.

Momentum traders have a straightforward map: sustained trade above 159.50 opens a run toward 160.00, but a breakout that quickly falls back below 159.50 would warn of exhaustion. If 159.00 gives way, we'd look toward 158.50 as the next downside zone rather than fighting for longs in the middle of a pullback.

USD/CHF complicates any simple dollar-strength story. It's down 0.23% at 0.8099, while USD/CAD has eased 0.12% to 1.3859. Treat USD/JPY as its own momentum trade and demand confirmation at resistance.

• •Setup: A confirmed hold above 159.50 favors continuation toward 160.00. A rejection followed by a loss of 159.00 shifts attention to 158.50.

GBP/USD and AUD/USD: Don't Ignore the Opening Weakness

GBP/USD is 0.17% lower at 0.7375 after a previous 0.73874 reading. The nearby 0.7400 handle is resistance until reclaimed. Sellers can watch for failed rallies into 0.7390-0.7400, while a break below 0.7370 would put 0.7350 into play. A sustained move above 0.7400 invalidates that immediate bearish structure and could trigger a deeper rebound.

AUD/USD shows the largest percentage decline in the supplied FX board, down 0.60% at 1.4035 from 1.4120. That makes 1.4000 the critical support zone for the next leg. A decisive break below it would confirm continuation pressure; if buyers defend 1.4000, 1.4120 becomes the obvious recovery benchmark.

There are no economic events listed in the supplied calendar, so opening-range behavior and technical confirmation deserve extra weight. For PropDynamiq traders, that means keeping execution simple: wait for breaks, retests and failed breakouts rather than predicting turns before price confirms them.

• •Setup: Favor GBP/USD shorts below 0.7400 while watching 0.7350; on AUD/USD, use 1.4000 as the decision point between continuation and a rebound toward 1.4120.

Key Takeaways

Monday's best setups sit around clear psychological levels, so confirmation matters more than chasing the opening move.

• •EUR/USD: 0.8600 is pivotal; a confirmed break favors 0.8580, while a defense can target 0.8645.
• •USD/JPY: Watch 159.50 for breakout confirmation toward 160.00; losing 159.00 weakens the bullish structure.
• •AUD/USD and GBP/USD: Focus on 1.4000 and 0.7400 respectively, using failed retests to define entries and invalidation.
