There is no hindsight, there are always clear points and directions. At this position, look at the yellow line segment in Figure 1. At present, it is a top divergence plus trend line suppression. The demand for a correction at this position is further strengthened. I think there is no volume support at this position. There is not much room above. The short-term correction space is estimated to be not very large, between 65500-66100. In fact, I think the final upper position is around 72000, but it may not be reached in the short term. In addition, I am a spot position. At this position, I will sell 2 layers slightly and wait for the next best position to increase the position.
