Negative oscillators on the 4-hour chart indicate that any further upward movement can be viewed as a selling opportunity.

From a technical standpoint, the presence of negative oscillators on the 4-hour chart suggests that any subsequent upward movement may be considered a chance to sell. In this case, the USD/JPY pair is likely to encounter resistance around the 200-period simple moving average (SMA) on the 4-hour chart, which currently lies near the 144.35 level. A break above the horizontal barrier at 144.50 would open the way for a test of the psychological level at 145.00.

On the other hand, support may emerge around the 143.75 level, followed by 143.30, which comes ahead of the key 143.00 level. If these levels fail to hold, it would confirm a short-term bearish bias and increase the risk of an accelerated decline toward the monthly low near 142.65. In such a scenario, the downtrend may extend further, leading to a test of lower levels.
