There are many ways to judge the long and short sides, mainly the following:
1, the ratio of the inner disk to the outer disk. If the inner disk is smaller than the outer disk, it is considered that many parties are dominant.
2. Look at the short-term rising speed of futures. If short-term futures rise rapidly, many parties will remain strong.
3. The number of outstanding orders between the buyer and the seller
4. Capacity of internal and external disks
5, K line, trend time-sharing line
Of course, these should be combined with the trend before futures and the stage of futures.
