Abstract: In a binary option structure, trades of buyers do not having counterpart trades of a market maker. Instead, for each order in a series, a digital processor assigns a zero value to orders whose barrier was not hit and for buyers whose barrier was hit calculates a distance between an entry price and the barrier, the digital processor ranking the distances of buyers associated with each order in the series. Upon expiration of the touch option, the digital processor divides the ranking into a winning part and a losing part and calculates payouts to buyers in the winning part by dividing the total investment series, less any commissions, among buyers in the winning part of the ranking. A display structure seen by participants shows current ranking. In response, buyers can move their barrier after placing the order, provided the barrier was not been hit, and without crossing the entry price.
