Can anyone help??? I want to make a program that will calculate and count down time decay for binary Fx options in 24hrs and a 1 week timeframe. Example..... All or nothing (0-100) buy call option eur/usd to be above 1.3700. I want to see the time decay count down as the spot price moves up, down or sideways in regards to my strike price in the desired timeframes.
