Moving Average

What Is a Moving Average?

A moving average (MA) takes the closing prices of a set number of periods and averages them, creating a single smooth line on your chart. As each new candle closes, the oldest price drops out and the newest is added, so the average "moves" with the market. The two most popular types are the Simple Moving Average (SMA), which weights all prices equally, and the Exponential Moving Average (EMA), which gives more weight to recent prices.

Common Moving Average Strategies

The most basic signal is a crossover: when price crosses above the MA, it is considered bullish; below, bearish. A more reliable approach uses two MAs: a faster one (like the 20-period) and a slower one (like the 50-period). When the faster MA crosses above the slower, it signals a potential uptrend ("golden cross"). When it crosses below, a potential downtrend ("death cross"). The 50 and 200-period MAs are the most watched by institutional traders.

Choosing the Right Period

Shorter MAs (10-20 periods) react quickly and work well for short-term trading but produce more false signals. Longer MAs (50-200 periods) are slower but more reliable for identifying the dominant trend. Many traders use multiple MAs: a short one for entries, a medium one for trend direction, and a long one for the big picture. Moving averages work best in trending markets. In ranging conditions, prices whipsaw back and forth across the MA, generating false signals. Combine them with RSI (Relative Strength Index) or MACD (Moving Average Convergence Divergence) to filter out noise.
