Ideas for band currency selection: hot spots, sectors, volume-price ratio.
1. If you just blindly chase hot spots and don't understand that a drop in high volume is a precursor to a continued decline, and you don't know that the continued shrinking of trading volume is a buffer before a rebound, it will be easy to chase at the top of the mountain and end up at the bottom of the mountain.
2. If you just follow the trend and chase the sector, but do not know the rules of sector rotation, you are likely to pass by the skyrocketing sector every time and get the coins of the falling sector.
3. If you only look at the technical indicators headed by the relationship between volume and price, although you can make steady profits most of the time, you will not be able to benefit from skyrocketing coins.
Therefore, this requires the volume-price ratio of hot-spot sectors to be used in conjunction with each other in order to run through the entire process of buying low and selling high in the band, so as to get twice the result with half the effort.
