What is the purpose of a moving average in trading?

The purpose of a moving average in trading is fundamentally linked to its ability to create averages of different subsets of data, which helps traders identify trends in price movements over a specified period. By calculating the average price of a security over a set timeframe, a moving average smoothens out the volatility and noise in price data, making it easier for traders to discern the underlying trend.

This analytical technique allows traders to recognize whether the asset is in an uptrend, downtrend, or a sideways market, enabling them to make more informed decisions about buying or selling. For instance, when the price is above the moving average, it might indicate an upward trend, while the opposite could suggest a downward trend. Importantly, moving averages can help establish support and resistance levels based on historical price behavior, further enhancing their utility in strategic trading decisions.
