In a process of computing both averages we use some number of last price values (= Number of Periods; normally around 20). Consider a price of the last trade and the previous one . Gain has positive value when , otherwise it is equal to zero. Loss can be defined in a similar way. It has positive value when , otherwise it is equal to zero.
