<p>Fibonacci numbers and lines, derived from the Fibonacci sequence, are widely used in technical analysis to identify support and resistance levels, as well as potential price targets. This sequence, starting with 0 and 1, adds the two preceding numbers to generate the next one (e.g., 0, 1, 1, 2, 3, 5, 8, 13, ...).</p>

<h2>How It Works</h2>
<p>Fibonacci lines are drawn on charts by connecting the highest and lowest points of a price swing. The resulting lines are then extended to identify potential support and resistance levels. These levels are calculated using Fibonacci retracement and extension levels, which are based on the Fibonacci sequence.</p>
<ul>
  <li><strong>Fibonacci Retracement Levels</strong>: These are ratios of the Fibonacci sequence used to identify potential support and resistance levels. Common retracement levels are 23.6%, 38.2%, 50%, 61.8%, and 78.6%.</li>
  <li><strong>Fibonacci Extension Levels</strong>: These are used to identify potential price targets. Common extension levels are 127.2%, 161.8%, and 261.8%.</li>
</ul>
<p>To use Fibonacci tools on MetaTrader 5, traders can add the Fibonacci retracement and extension tools from the <strong>Insert</strong> menu.</p>

<h2>Why It Matters for Traders</h2>
<p>Fibonacci numbers and lines matter to traders because they provide a framework for analyzing price movements and making informed trading decisions. By identifying support and resistance levels, traders can:</p>
<ul>
  <li>Enter trades at more favorable prices</li>
  <li>Set stop-loss orders to manage risk</li>
  <li>Identify potential profit targets</li>
</ul>

<h2>Example</h2>
<p>Let's say a trader is analyzing the EUR/USD pair on MetaTrader 5 and wants to use Fibonacci retracement to identify potential support levels. The trader would first identify the highest and lowest points of the current price swing. If the swing high is 1.2000 and the swing low is 1.1500, the trader would draw a Fibonacci retracement line from 1.2000 to 1.1500. The line would then display the following retracement levels:</p>
<table>
  <tr>
    <th>Fibonacci Level</th>
    <th>Price Level</th>
  </tr>
  <tr>
    <td>0.0%</td>
    <td>1.2000</td>
  </tr>
  <tr>
    <td>23.6%</td>
    <td>1.1687</td>
  </tr>
  <tr>
    <td>38.2%</td>
    <td>1.1614</td>
  </tr>
  <tr>
    <td>50.0%</td>
    <td>1.1672</td>
  </tr>
  <tr>
    <td>61.8%</td>
    <td>1.1636</td>
  </tr>
  <tr>
    <td>78.6%</td>
    <td>1.1600</td>
  </tr>
  <tr>
    <td>100.0%</td>
    <td>1.1500</td>
  </tr>
</table>
<p>The trader can now use these levels to identify potential support zones and make more informed trading decisions.</p>
