$FOLKS I remember that the cost for the long position yesterday was 7 dollars, and what about the cost for the short position? I found that both of their costs have decreased. Today the cost for the long position has changed to 5.8, and the cost for the short position has changed to 7.47.

However, there is a strange phenomenon: yesterday the short position made 4 million, and normally today it should make more, but I don't know why it shows that the profit has decreased.
