MA (moving average) is called the moving average indicator. \x0d\ calculation formula \x0d\ 1. N-day moving average = sum of closing prices on n days /N (arithmetic average) \x0d\2. To set multiple moving averages, the general parameters are set to n 1 = 5, N2 = 10 and n3 = 20. Calculation formula \x0d\ 1. EXPMA=[ closing price of the current day or period * 2+ expma of the previous day or period * (n-1)]/(n+1) \ x0d \ 2. For the first time, the EXPMA value of the previous issue is yesterday's expma value, and n is the number of days. \x0d\ 3。 Multiple indicator lines can be set with the parameter12,50 (12,50). \x0d\ 4。 Function: MA 1:EMA(CLOSE, p1); MA2:EMA (approach, p2); MA3:EMA(P3 Close); MA4:EMA (close, P4)\x0d\ EMA and EXPMA have the same calculation principle.
