$PERP feels that it can’t be pulled anymore. This position can be empty first, and then fill up when it rises! Don't stud directly, the fluctuation is very large, the small position is advanced, and the position can be covered when it rises, and the average price can be pulled.
This kind of pull is definitely going to fall all the way. At present, it is almost at the top, and the forecast is around 0.88, 0.94!
