Quote from Twinsen:
I cannot understand why he uses a short butterfly instead of a credit spread (see in his webinar 38th minute)? Stock at 620.
615 -1 5.0
620 +2 0.73
625 -1 0.00
credit received: 3.54
What is the point of using 625 here?
Also it is not clear to me what will happen with this spread later because the short 615 is in the money. Do I need to buy it back or let it expire? And if I buy it back what will be my profit in result?
