Quote from IV_Trader:
why ???
Not the brightest bulb on the block here, but it seems to me that you would have to have some expectaton that ISRG was going to revert towards 130 to want to fly this trade. From what I can see, the choice was take an $8 and change profit now or risk $6 of it to go for a max of $17. From there it seems like it's an judgement call.
