Most of the time when I use the Options Play calculator to establish my bull call vertical it selects the upside call I am selling to generate very little premium. Seems this provides very little benefit vs just buying the long call. Example being bull call spread on Gilead shows buying the in the money call for $5.45 and selling the upside out of the money call for only $0.46 (10/17 expiration). Very little benefit to selling the upside call. Thoughts??
