How to try the top?
When it just rose to 80,000 two days ago, it did not reach the integer mark and retrace quickly and sharply like before. I immediately judged that it would be possible to enter the market if it fell back to 78,800-78,666, which is likely to be a bottom-fishing. As a result, it broke through and stabilized at 8w the next day. In fact, the most stable way to determine whether it can stabilize at the 8w mark and start preparing to attack 9w is to wait for it to rise to around 81,600 and retest 78,800 once before entering the market, and it will be very safe to chase the rise. (Why 81,600? This is the first pressure point above 8w)
Similarly, it fell back 5k points to around 9w yesterday. Although it also probed around 9w twice, the retracement was larger than that of reaching around 8w, and it has risen nearly 25,000 points since Trump's election day, so there is a certain room for a correction, so it can be conservatively chased here. So yesterday and today, the retracement entered more, and all profits can be stopped at 8.8-8.9w. If you really want to continue attacking 10w, it will be safest to wait for it to rebound to 91600 and then enter the market when it falls back to 88800-88600, and this is the place to buy at the bottom.
