<p>The ISO currency code is a three-letter alphabetic code defined by the International Organization for Standardization (ISO) to represent a currency. It's a crucial component in the foreign exchange (Forex) market, enabling seamless transactions between different currencies.</p>

<h2>How It Works</h2>
<p>The ISO currency code is a standard way to denote a currency in the Forex market. It's used in various financial systems, including MetaTrader 5, the popular trading platform offered by STB Provider. The first letter represents the currency's major unit, the second letter represents the currency's minor unit, and the third letter is a check digit used for error detection.</p>
<p>For instance, the ISO currency code for the US Dollar is 'USD'. Here, 'U' represents the major unit, 'S' represents the minor unit (cent), and 'D' is the check digit.</p>

<h2>Why It Matters for Traders</h2>
<p>The ISO currency code is vital for traders as it helps in:</p>
<ul>
  <li><strong>Precision</strong>: It ensures accurate representation of currencies, preventing errors in transactions.</li>
