After the price broke through the previous high, it retraced. When the price dropped near the previous high point (at the circled area), it was blocked by the previous high. We can enter a long position using the previous high as a support level. It is important to remember that the previous highs and lows are not precise points, but rather a price range. As shown in the chart, the price may oscillate around the previous high before rising again or even breaking below the previous high. Therefore, any resistance and support levels should be viewed as price ranges rather than exact points.
