one thing that makes me not interested in binary options is ..., because Binary options are similar to gambling ... because I see Binary Options only adopt one close position mode, which is expiry time. This feature can automatically close binary options in accordance with the size of the time that you set yourself. For example, if you open a EUR / USD "call" option with an expiry time of 1 hour, the option will only last for 1 hour. When the expiry runs out, the "call" option will close automatically. This expiry can be very important, because when it is closed the price is not at a higher level than its original position, the option means out-of-the-money (failure or loss). The selection of this expiry time can be adjusted to your trading period.
