Options available on the Dopex platform are known as “European”. The key feature of a European option is that it can be exercised only at the expiration, during a specified time window. If, at this time, the value of the option is positive (the spot price is above the strike price for call options or below the strike price for put options), exercising the option would result in some gains to the option holder. One trick though - the person holding the option has to declare they exercise it. If they don’t do this, the option will expire worthless. Obviously, buying an option, having a profitable position and failing to exercise it is going to be a frustrating experience for users. For this reason, you can use an auto-exercising contract. This contract will exercise all the profitable positions for the user.
