its to prevent a buyer from getting rugged on a strike price they didn't intend to purchase the option for
there'd be a race condition upon a pending buy where the seller could cancel the call and create a new one with the same premium but higher strike price

this should be moved above any of the external calls. Currently the seller could re-enter and cancel after receiving premium :)
