1. Short-term: refers to stocks held for a short time after buying. If they are only held for one or two days, they will be sold after three or five days at most.

Second, the midline: the holding time is at least one month or even more than half a year.

3. Long-term: held for more than one year or several years.

Fourth, the band: the band is not based on the length of time. It is based on technical trends, such as band holding. The trend of stocks is nothing more than rising, falling and consolidation. In these three trends, rising forms an upward band and falling forms a downward band. If the band is held, it will not be sold during the rising process until the end of the rising band. It may be a week or three months.
