Breakeven rectangle overlay for move contract

I'm sharing this little script allowing you to display a breakeven rectangle for the move contract after manually writing your parameters (strike price, contract price). In case you are long your breakeven (at expiration) is when the price expire outside the rectangle. In case you are short your breakeven (again at expiration) is when the price is staying inside the rectangle at expiration. You can change multiple personalisation parameters as you wish.
