In a unilateral upward trend, the focus of contracts is on short-term and ultra-short-term pullbacks for replenishing positions and taking profits on short-term rebounds. Because once it rises, there may be several months without significant pullbacks, and the daily movements are usually slight pullbacks. If you perceive the amplitude of the pullbacks as too large, you may miss out; the more it rises, the more you miss. Therefore, contracts should not remain static in an upward trend without making adjustments; short-term trading emphasizes compound interest. Why don't I need to just hold onto one position? I can capture pullback points every day to replenish positions, achieving compound interest and greater profits. If it moves from 1 to 3, the profit is 2; if it pulls back to 2 and I replenish, the profit is above 3, which is more than 33% extra profit. If you hold it without action, don't take profits on rebounds, and don't replenish on pullbacks, your profit will only be 2. You can't eat a big meal in one bite, but accumulating small amounts can lead to more. A small accumulation can become a great depth, and wind and rain arise from it.

If you aren't making much money during a unilateral rise, waiting for a significant pullback in the future to make profits won't be as easy as now, and your confidence won't be as strong as it is now. Human nature drives people to seek higher ground; when a significant pullback occurs, you will hesitate and worry about whether it can rise again, rather than seeing it as a great opportunity. When you are on the mountain, the view down is scenic, but when you reach the bottom and look up at the peak, that distance feels unattainable.
