After surging to the 3.149 level, there was some pullback in the afternoon. Currently, it remains around 3.1, showing signs of accumulation at higher levels.

On the four-hour chart, the head and shoulders pattern is obvious, but no effective breakout has formed. Next, focus on whether the 3.150 resistance holds. There is also significant room for a pullback below, and since it is at a high point, consider a cautious approach with a slight upward bias to watch for a pullback.

Enter in the opposite direction, watch around 3.120 for control, with the target between 3.030-3.050.
