A WMA, to nie jest żadna średnia ważona (weighted), tylko WilderMovingAverage,
średnia smoothed, więc jak się nie znasz, to nie pi*rdol człowiekowi głupot.
A, i tak cię lubię.
Żółta to WMA(13)Close, biała to EMA(27)Close.Welles Wilder's Moving Average Formula
The standard exponential moving average formula converts the time period to a fraction using the formula EMA% = 2/(n + 1) where n is the number of days. For example, the EMA% for 14 days is 2/(14 days +1) = 13.3%. Wilder, however, uses an EMA% of 1/14 which equals 7.1%. This equates to a 27-day exponential moving average using the standard formula.
