What are Moving Averages?
Moving Averages are trend-following or lagging indicators because they are based on past price data. They average out the price of an asset over a specific period, helping traders identify the direction of the trend and potential support or resistance levels. The most common types of Moving Averages used in trading are:
- Simple Moving Average (SMA): This is the average price over a specified number of time periods. It gives equal weight to each price point within the period.
- Exponential Moving Average (EMA): This type gives more weight to recent prices and reacts more quickly to price changes than SMA.
How Do Moving Averages Work?
Moving Averages work by smoothing out price fluctuations and making it easier to identify the overall trend. Here’s how they can be applied in trading:
- Trend Identification: An upward-trending MA suggests a bullish market, while a downward-trending MA indicates a bearish market.
- Support and Resistance: Prices often bounce off MAs, which can act as support in a bullish market or resistance in a bearish market.
- Crossovers: When a shorter-period MA crosses above a longer-period MA, it can signal a buying opportunity (bullish crossover). Conversely, when a shorter-period MA crosses below, it may suggest a selling opportunity (bearish crossover).
