Moving averages: MA vs EMA settings and uses

A moving average averages price over a window, filtering noise so the trend shows through. Understand it and many other indicators make more sense.

MA vs EMA

A simple MA weights every candle in the window equally; an EMA weights recent prices more, so it turns faster and is more easily whipped by short-term moves. Use EMA to hug current price, MA for smoothness.

Choosing periods

There's no magic number, but a common short/medium/long stack is 20 / 60 / 120 (or 250). Short reads sentiment; long reads the big picture. Longer periods are smoother but lag more.

Three common uses

• Direction: price above the MA leans bullish, below bearish; MAs stacked in order (alignment) means a healthy trend.
• Crosses: a short MA crossing above a long one is a golden cross (bullish), below is a death cross — reliable in trends, noisy in ranges.
• Dynamic S/R: in uptrends price often bounces off the MA; combine with support & resistance.
