Regarding the pickup code,

1: First, the first take-profit level is 53, and the lowest point is 535.
The stop-loss is 621. After the pickup code was updated, the stop-loss was slightly broken, but I still held on after the reminder in the tweet.
2: Tonight, the 57 level couldn't go down, so the second take-profit is unlikely. If the 57 level breaks below, you can wait for the second take-profit level. The short-term high is around 67.5.
