Webb31 mars 2024 · The formula for calculating the EMA is as follows: As exemplified in the chart above, EMAs calculated over a fewer number of periods (i.e., based on more recent prices) show a higher weightage than those calculated over longer periods. It can be shown by calculating the value of “K” for two different time periods: WebbH ( ω) = ∑ (m = − ∞ to ∞) h ( m) e− jωm. The impulse response of an L -sample moving average is h ( n) = 1/ L, for n = 0, 1, ..., L − 1 h ( n) = 0, otherwise Since the moving average filter is FIR, the frequency response reduces to the finite sum H ( ω) = (1/ L) ∑ (m = 0 to L − 1) e− jωm .. We can use the very useful identity
