Some brothers may ask, since you are so optimistic about the rise, why not heavily invest or go all in around 78,000? What I want to say is, what if I'm wrong? Where do you set your stop loss? If it's too small, you might get stopped out easily; if it's too large, and I'm wrong, the loss would be too much. And why must we wait until after breaking 79,000 to add positions? Because of certainty and timing. What we do with contracts is the price difference, which has nothing to do with cost, only whether there's a price difference after entering. Many people are misled; left side and right side are just relative concepts, there’s nothing that can’t be done. The key is whether it matches your trading system and how you use it. To rise afterwards, it must break 89,000, which is inevitable. If it breaks after sufficient consolidation, you are chasing the rise, not chasing a high. Because highs and lows are relative; as long as you chase in and it keeps rising, it is not called chasing a high.
