Moving average is a technical analysis tool used to smooth out short-term fluctuations in data points by creating a constantly updated average of a certain number of data points. It is used to identify trends and support and resistance levels in a stock's price action.

Moving average (MA) is a technical analysis tool used to identify trends in financial markets. It is a type of lagging indicator, meaning it is based on past data and is used to predict future price movements. The moving average is calculated by taking the average of a certain number of past data points, usually the closing prices of a security over a certain period of time.
The most common type of moving average is the simple moving average (SMA), which is calculated by taking the average of the closing prices of a security over a certain period of time. For example, a 10-day SMA would be calculated by taking the average of the closing prices of the security over the last 10 days. The SMA is used to identify the overall trend of a security, as well as to identify potential support and resistance levels.
The exponential moving average (EMA) is another type of moving average. It is similar to the SMA, but it gives more weight to recent data points. This makes it more responsive to recent price movements, which can be useful for traders looking to identify short-term trends.
Moving averages can also be used to identify crossovers, which occur when a shorter-term moving average crosses above or below a longer-term moving average. Crossovers can be used to identify potential buy and sell signals.
Moving averages can be used in combination with other technical analysis tools to identify potential trading opportunities. They can also be used to identify potential support and resistance levels, as well as to identify potential trend reversals. However, it is important to remember that moving averages are lagging indicators, meaning they are based on past data and are not always reliable for predicting future price movements.
