The so-called Masukura is relative. Let's put it this way, if it is 100 lots, which corresponds to 100 lots, then Masukura is actually 0 lots, because the bulls have not increased, but the individuals have changed.

If 100 lots are multi-open, that is to say, 50 lots are multi-flat and 50 lots are empty, then the actual position is 50 lots (500 lots are long and 500 lots are empty).

2. If one of the buyers and sellers is the original trader, the position will remain unchanged.

3. If both buyers and sellers are original traders, and both positions are closed, the position will be reduced.
