Market Open: Dollar Slips Into Key Support Zones Ahead of US Session (Aug 3)

USD Weakness Tests Multi-Session Levels

The biggest move overnight came from USD/JPY, dropping hard to 156.68 from 160.24 (-2.22%). That’s not noise—that’s a structural shift pushing price straight into a support band we’ve been watching between 156.00–156.50. This zone held twice in July.

If buyers defend here again, we could see a corrective bounce back toward 158.20. But a clean break below 156.00 opens the door to 154.80 quickly. Momentum favors sellers for now, but this is not a chase zone—this is a reaction zone.

Across the board, USD pairs are soft. EUR/USD is down to 0.8669 (-0.43%), grinding toward a key support at 0.8650. GBP/USD is tracking similarly at 0.7424, sitting just above 0.7400, a psychological level that’s been sticky.

• •Key level: USD/JPY 156.00 support — break = continuation, hold = bounce setup

EUR/USD Compression: Breakout Brewing

EUR/USD has been compressing for three sessions, and we’re now right at the lower edge of that range. Price is leaning on 0.8650 support with lower highs forming—pressure is building.

If we break and hold below 0.8650, the next downside target sits around 0.8615. On the flip side, any reclaim above 0.8700 flips short-term structure back bullish and traps late sellers.

This is classic range breakdown vs fakeout territory. The first move might not be the real move, so patience matters here.

• •Trade idea: Break below 0.8650 → target 0.8615 | Reclaim 0.8700 → squeeze toward 0.8740

GBP/USD and AUD/USD Divergence

GBP/USD is weaker alongside the dollar move but not breaking down aggressively. Price is hovering above 0.7400, a level that’s acted as both support and resistance over the past two weeks.

A breakdown below 0.7400 likely accelerates toward 0.7350. But if buyers defend it again, we’re looking at another rotation back toward 0.7470.

Meanwhile, AUD/USD is the outlier, pushing higher to 1.4272 (+0.16%). That’s testing resistance near 1.4300. If it breaks clean, we could see a continuation move toward 1.4350. If it fails, expect a sharp pullback—this pair tends to move fast once momentum stalls.

• •Key divergence: AUD/USD strength vs broad USD weakness—watch for continuation or sharp rejection at 1.4300

What to Watch Into US Open

We’re entering the US session with multiple pairs sitting right on decision points. That usually means volatility expansion is coming.

Dollar sentiment is bearish overall, but we’re not at fresh breakdown levels—we’re at support. That changes how we approach trades. Selling into support is risky unless we get confirmation.

For traders using PropDynamiq to compare execution conditions, this is the kind of session where spreads, slippage, and speed matter most—especially around breakout levels.

• •Trigger mindset: Wait for confirmation breaks or clean rejections—avoid mid-range entries
