<p>Lagging indicators are a type of technical analysis tool that follows price action, confirming trends after they have already begun. They are called 'lagging' because they react to changes in the market after the fact, providing signals that a trend is in place, but not necessarily the start of the trend.</p>

<h2>How It Works</h2>
<p>Lagging indicators work by smoothing out price data over a specific period. This is typically done using moving averages, which calculate the average price over a set number of periods. Other examples include the <a href="/NewSite/encyclopedia/moving-average/" class="ency-link">Moving Average</a> Convergence Divergence (MACD) and the Average Directional Index (ADX). These indicators help to filter out noise and provide a clearer picture of the overall trend.</p>

<h2>Why It Matters</h2>
<p>Lagging indicators are useful for confirming trends and generating buy or sell signals. They can help traders to identify when a trend is strong and likely to continue, or when it may be losing momentum. However, they are not useful for predicting trend changes or generating early entry or exit signals. Therefore, they are often used in conjunction with leading indicators to provide a more comprehensive view of the market.</p>
