The Simple Moving Average (SMA) is a statistical calculation used to analyze data points by creating a constantly updated average price over a specific period. It is commonly used in financial markets to smooth out price fluctuations and identify trends by averaging the closing prices of a security over a predetermined number of days, such as 10, 20, or 50 days. The SMA helps traders and analysts detect potential support and resistance levels, as well as generate buy or sell signals based on the interaction between the SMA and the asset’s price.
