Is there a site where I can plug in some options and it spits out a profit/loss diagram? I am interested in creating a structured note-like option model using GLD. I would like to see if I can create the note I saw where you get 2x the upside until 35% profit, if the price goes down 10% you lose no money, but after that you lose dollar for dollar. So basically you are capped at 35% for 2 yrs, you have the safety of not losing money if GLD goes down 10%, anything more than 10% loss you lose dollar for dollar. Any help would be appreciated.
