Yesterday's dynamic alert: "...current 828, defend 825...", actually triggered stop loss at 825, dropped to a low of 812, then quickly pumped back, currently 821.

The Fibonacci 618 of 766-887 is precisely 812, and the retracement has reached a key level.
812 has completed 3 segments, and the current price is above the significant high point of 81992. It is advisable to maintain a rebound expectation and go long, with defense points at 812/809 and a short-term target of 830/838.
