<p>Economic Order Quantity (EOQ) is a calculation used to determine the optimal order size for inventory management, balancing ordering costs and holding costs. It's a fundamental concept in operations management, widely applicable in various industries, including trading.</p>

<h2>How It Works</h2>
<p>EOQ is calculated using the following formula:</p>
<table>
<tbody>
<tr>
<td><strong>EOQ</strong></td>
<td>= √(2DS / H)</td>
</tr>
</tbody>
</table>
<p>Where:</p>
<ul>
<li><strong>D</strong> is the annual demand for the item (in units)</li>
<li><strong>S</strong> is the order cost (in currency)</li>
<li><strong>H</strong> is the holding cost (in currency per unit per year)</li>
</ul>
<p>Here's how it works:</p>
<ol>
<li>Estimate annual demand, order cost, and holding cost.</li>
<li>Plug these values into the EOQ formula.</li>
<li>The result is the optimal order size that minimizes total inventory costs.</li>
</ol>

<h2>Why It Matters for Traders</h2>
<p>In trading, EOQ helps manage risk and optimize costs. Here's why it matters:</p>
<ul>
<li><strong>Risk Management:</strong> EOQ helps control inventory risk by ensuring you don't tie up too much capital in inventory.</li>
<li><strong>Cost Optimization:</strong> It minimizes total inventory costs, including ordering and holding costs.</li>
<li><strong>Efficiency:</strong> EOQ helps streamline operations, reducing the time and effort spent on frequent, small orders.</li>
</ul>

<h2>Example</h2>
<p>Let's say you're a forex trader using <strong>MetaTrader 5</strong> and you want to determine the optimal lot size for your trades. You estimate:</p>
<ul>
<li>Annual trading volume (D): 100,000 lots</li>
<li>Transaction cost (S) per trade: $10</li>
<li>Holding cost (H) per lot per year: $50</li>
</ul>
<p>Plugging these values into the EOQ formula gives:</p>
<table>
<tbody>
<tr>
<td><strong>EOQ</strong></td>
<td>= √(2 * 100,000 * $10 / $50) = 400 lots</td>
</tr>
</tbody>
</table>
<p>So, the optimal lot size for your trades is 400 lots.</p>
