<p>The <strong>Price Rate of Change Indicator (ROC)</strong> is a momentum oscillator that measures the percentage change in price over a specified period. It's a popular tool among traders, helping them identify trends, potential reversals, and overbought/oversold conditions.</p>

<h2>How It Works</h2>

<p>The ROC indicator is calculated using the following formula:</p>

<table>
  <tr>
    <td><strong>ROC</strong></td>
    <td>= [(Close - Close<sub>n</sub> periods ago) / (Close<sub>n</sub> periods ago)] * 100</td>
  </tr>
</table>

<p>Where:</p>
<ul>
  <li><strong>Close</strong> is the current closing price</li>
  <li><strong>Close<sub>n</sub> periods ago</strong> is the closing price <strong>n</strong> periods ago</li>
  <li><strong>n</strong> is the number of periods in the lookback period</li>
</ul>

<p>The default setting for <strong>n</strong> is 12 periods, but traders can adjust this value based on their preference or the specific instrument they're trading.</p>

<h2>Why It Matters for Traders</h2>

<p>The ROC indicator matters for traders because it helps them:</p>

<ul>
  <li>Identify trends: A positive ROC suggests an uptrend, while a negative ROC indicates a downtrend.</li>
  <li>Find potential reversals: Divergences between the ROC and price action can signal a trend reversal.</li>
  <li>Spot overbought/oversold conditions: Extreme ROC values can indicate that an asset is overbought or oversold, presenting potential entry or exit points.</li>
</ul>

<h2>Example</h2>

<p>Let's say you're using the ROC indicator on MetaTrader 5 to analyze EUR/USD. The default setting is 12 periods. If the current closing price is 1.1850 and the closing price 12 periods ago was 1.1500, the ROC would be:</p>

<table>
  <tr>
    <td>(1.1850 - 1.1500) / 1.1500 * 100 = 3.04%</td>
  </tr>
</table>

<p>This positive ROC value suggests an uptrend in EUR/USD.</p>
