For SOL, a review is of great help to us to improve short- and medium-term trading. My review is different from others, there are a lot of verbose things, you may not understand or necessarily practical. I will only talk about the most important things: how the point comes from and the basis for judgment. On the day of 8.1, after the SOL pullback fell below 170, I had basically confirmed that the SOL pullback to around 155-157 would stop falling, which is the dip buying point. It is definitely the first person on the whole network to judge that this is the bottom buying point, and I see that many people stop falling after 8.3 and start to judge that it is too slow. Because this is the golden section point of the large band of 125-206, if it falls further, it will turn to a bearish trend. Then from 155 as the starting point, how much will it rebound? I also spoke in the ban group for the first time (as shown in Figure 3), and the rebound was 175, 181, and 186 in order. How did these three points come about? The lowest point is 155.5+(206-155.5)*0.382/0.50/0.618, respectively. 186.5 is just the highest point last week, and it is also the position where 155.5 has recovered to 0.618 since it stopped falling and rebounded. At that time, after confirming the dip point at 155.5, I quickly said that it was not too much to recover 30 points after a pullback of 50 points. Looking back now, 155.5+30=185.5. It has just recovered 30 pips. So by the time it was around 186, Fiporeci's three rebound points had all arrived. Then yesterday I also said that in the short term, it will be confirmed that 177 is firm from 186 to below 180, and then it will attack 200. That's what is about to happen this week. As soon as 186.50 breaks through in the short term, you can also chase up and cover the position, and the part of the increase will be unloaded at 189-191 first. This is called rolling. Why can I cover my position after breaking through 186.5? Because the bulls will become stronger if they break through the 0.618 position. It is the same as last night that if ETH breaks through 4266 (yesterday's daytime decline recovered the 0.618 position), you can chase the current price and cover the position.
