<p>A <strong>currency pair</strong> is the quotation of two different currencies, where the value of one currency is expressed relative to the other. In the foreign exchange market, every trade involves buying one currency and simultaneously selling another, which is why prices are always shown as pairs such as EUR/USD or GBP/JPY.</p>

<h2>How It Works</h2>
<p>The first currency in the pair is the <strong>base currency</strong>; the second is the <strong>quote currency</strong>. The price indicates how many units of the quote currency are needed to purchase one unit of the base currency. For example, an EUR/USD rate of 1.0850 means one euro buys 1.0850 U.S. dollars. Trading platforms like <strong>MetaTrader 5</strong> display these rates in real time and allow traders to open long (buy) or short (sell) positions on the pair.</p>
<p>The difference between the buying (ask) and selling (bid) price is the <strong>spread</strong>, measured in <strong>pips</strong>. A <a href="/NewSite/encyclopedia/pip/" class="ency-link">pip</a> is the smallest price movement, typically 0.0001 for most pairs. Traders monitor spreads and pip values to calculate potential profit or loss.</p>

<h2>Why It Matters for Traders</h2>
<p>Understanding currency pairs is essential because it determines how market movements affect a position. When the base currency strengthens against the quote, a long position gains value; when it weakens, the position loses value. Conversely, a short position profits from a decline in the base currency. Knowledge of pair characteristics—such as volatility, liquidity, and typical <a href="/NewSite/encyclopedia/spread/" class="ency-link">spread</a>—helps traders choose instruments that match their risk tolerance and strategy.</p>
<p>Pairs are grouped into majors, minors, and exotics. Majors involve the U.S. dollar and are the most liquid, often featuring tighter spreads. Exotics pair a major currency with one from an emerging market and tend to have wider spreads and higher volatility, which can increase both opportunity and risk.</p>

<h2>Example</h2>
<p>Assume a trader opens a long position on EUR/USD at 1.0850 with a lot size of 10,000 euros. If the price rises to 1.0900, the gain is 50 pips. Since each pip for a mini lot (10,000 units) equals 1 USD, the profit is 50 USD. If instead the price falls to 1.0800, the loss is 50 pips, or 50 USD. The trader’s net result depends on the entry price, direction, and the spread paid at execution.</p>
