I had to scramble mightily to get these on at the 11 CST pop/VXST/VIX ratio of >1.15, first opening the 14/17 for a 2.25 debit and then the 15/18 for a 2.20 debit ... .
The break even for the former is 14.75 with a max profit potential of 75/contract and a 15.80 break even for the latter with a max profit potential of 80/contract.
