What is a Moving Average?

A moving average smooths price fluctuations to reveal the underlying trend. The SMA gives equal weight to all prices in the period. Longer periods create smoother lines that react slower to price changes. Popular periods are 20 (short-term), 50 (medium-term), and 200 (long-term).

How to Read Moving Averages

When price is above the MA, the trend is generally bullish. When below, bearish. The slope of the MA shows trend strength. Multiple MAs can show trend at different timeframes - when faster MAs are above slower MAs, it's bullish (stacking).

Trading Signals

Key signals include: Price crossing the MA (trend change), MA crossovers (Golden Cross: 50 crosses above 200, Death Cross: opposite), MA acting as dynamic support/resistance, and MA slope changes indicating momentum shifts.

Trading Strategies

Simple trend-following: Buy when price crosses above MA, sell when crosses below. Pullback strategy: In uptrend, buy when price pulls back to MA and bounces. Multiple MA system: Use two MAs and trade crossovers.

Formula

Formula
SMA = (P1 + P2 + ... + Pn) / n
where P = Price, n = Number of periods
