now to open short not so good.
now to sell Long not so good if you bought some long last Friday
For example if you buy some CBBC (long) last Friday around 25% IV, when market @ X price
Today your CBBC price may drop if the IV become 20%, when market price is X too.
Pls correct me if I understand this wrongly. ...
good morning all , and lofu hing!
