AMZN is at 3345 now and 30 JUL 21 3300C/3350C/3400C Call Fly can be bought for -0.67 credit. What does it mean? Can you really buy a fly for a credit? Is it because Vol is so low? I tried but didn't get a fill even for a small debit.
You answered your own question.... As for IC vs fly,an IC is a bunch of stacked flys.. As an example,look at the 10-15 25-30 IC.. It can be broken down to 3 5 pt flys on top of each other.. 10-15-20 + 15-20-25 + 20-25-30
