Masukura refers to the change of total positions (including long positions and short positions) on that day compared with yesterday. Masukura is positive, which proves that the number of positions has increased. Because long and short positions need funds, the increase in positions means the inflow of funds, indicating that more funds are paying attention to this variety, and the confrontation between long and short positions has also strengthened. Masukura is negative, which proves that the position falls, the funds flow out, and the funds withdraw and wait and see.
