The big pie meets pressure here at 79000 as expected. The current thinking is clear: buy on the dip. It's judged that the big pie will continue to rebound and correct before falling again, so the strategy is simple: buy back the previous long positions in batches when it dips to around 78000, with a stop loss set around 77400. It must be emphasized that what we're doing here is just a rebound market lasting about two to three days, not a reversal. The big pie will certainly continue to fall eventually; the more it rebounds, the greater the space for shorting later. It shouldn't be far off for the big pie to break below 70000, but before that, a rebound of a thousand points is also very possible. So for the next few days, let's first take profits from the long rebound, and after forming a structure, we can open shorts.
