Look for a smooth adjustment parameter exponential calculation for it and the various ways the study forecast. Conclude that the method how to forecast by exponential smooth as a method of time series forecasting using the most appropriate. Based on the measurement accuracy of a minimum equal to the MAD 0.022305035, 0.09146232, and 0.00002551 minimum minimum 0.000922720 MAPE, 0.009264273, and 0.015505682, the three lowest RMSE of currency is equal to 0.028619282, the currency of the country of Singapore 0.125242600. Malaysia, and how the interest rate, the lowest RMSE value equality is equal to 0.000168682 of the currency in Viet Nam.
