A plain EMA has one problem: it is either fast and noisy, or smooth and late. Adaptive and low-lag averages try to give you both. KAMA slows down in chop and speeds up in trends; ALMA and McGinley are smooth yet quick; DEMA and TEMA strip out most of the lag; WMA and VWMA weight recent or high-volume candles more.
The full lesson shows which one to use for which job, and a simple trend filter you can test today.
