<p>A <strong>national currency</strong> is the official currency issued and controlled by a country's government or central bank. It serves as the primary medium of exchange, unit of account, and store of value within that nation's economy.</p>

<h2>How It Works</h2>
<p>Each country has its own unique national currency, which is typically represented by a three-letter code, known as an ISO 4217 currency code. For instance, the United States uses the U.S. Dollar (USD), while the Euro (EUR) is used by countries in the Eurozone.</p>
<p>Central banks manage national currencies by implementing monetary policies that influence interest rates, money supply, and inflation. They aim to maintain stability and promote economic growth within their respective countries.</p>

<h2>Why It Matters for Traders</h2>
<p>National currencies play a crucial role in forex trading, as they are the building blocks of currency pairs. For example, the EUR/USD pair consists of the Euro (EUR) and the U.S. Dollar (USD). Understanding the economic health and political stability of a country can help traders make informed decisions about its currency's potential performance.</p>
<p>Traders can use platforms like <strong>MetaTrader 5</strong> to speculate on the rise or fall of national currencies against each other. With up to 1:300 leverage offered by STB Provider, traders can potentially amplify their profits, but they should also be aware of the increased risk involved.</p>

<h2>Example</h2>
<p>Consider the following example using the British Pound (GBP) and the U.S. Dollar (USD) on MetaTrader 5:</p>
<table>
<thead>
<tr>
<th>Currency Pair</th>
<th>Leverage</th>
<th>Trade Size</th>
<th>Pip Value</th>
</tr>
</thead>
<tbody>
<tr>
<td>GBP/USD</td>
<td>1:300</td>
<td>1 lot (£100,000)</td>
<td>£10 per pip</td>
</tr>
</tbody>
</table>
<p>If a trader believes the GBP will strengthen against the USD, they could open a long position with 1 lot (£100,000) at a leverage of 1:300. If the GBP/USD rate moves 100 pips in their favor, their profit would be £1,000 (100 pips * £10 per pip), amplified by the leverage used.</p>
