<p><strong>MetaTrader 5</strong> is an industry‑standard <strong>multi‑asset trading platform</strong> that enables retail and institutional participants to trade forex, commodities, indices, stocks and cryptocurrencies from a single interface. Developed by MetaQuotes Software, it succeeded MetaTrader 4 and introduces enhanced charting, a built‑in economic calendar, and support for both hedging and netting account types.</p>

<h2>How It Works</h2>
<p>The platform connects to a broker’s server using the MetaTrader 5 protocol, delivering real‑time price quotes and order execution. Traders can place market, limit, stop, and trailing‑stop orders directly from the chart or the trade tab. Built‑in analytical tools include 38 technical indicators, 44 graphical objects, and 21 timeframes, allowing detailed technical analysis across multiple symbols.</p>
<p>Automated trading is facilitated through <strong>Expert Advisors</strong> (EAs) written in the <strong>MQL5</strong> programming language. <a href="/NewSite/encyclopedia/mql5/" class="ency-link">MQL5</a> supports object‑oriented code, multi‑threaded strategy testing, and access to market depth data. Traders can backtest EAs on historical data, optimize parameters, and deploy them live via the platform’s strategy tester. The integrated Market and Code Base provide ready‑made indicators, scripts, and EAs that can be rented or purchased.</p>
<p>MetaTrader 5 operates on Windows, macOS (through a compatibility layer), and offers web and mobile versions, ensuring access from desktop browsers, smartphones, and tablets.</p>

<h2>Why It Matters for Traders</h2>
<p>The platform’s widespread adoption means liquidity providers and brokers typically offer MetaTrader 5 as a primary trading venue, reducing the learning curve when switching firms. Its multi‑asset capability lets traders diversify without juggling separate software. Advanced charting and a comprehensive library of custom indicators support sophisticated technical strategies.</p>
<p>The MQL5 environment lowers the barrier to algorithmic trading: beginners can modify existing EAs, while experienced coders can build complex systems that utilize tick‑by‑tick data and market depth. The strategy tester’s visual optimization and forward‑testing features help validate performance before risking capital.</p>
<p>Because many regulated brokers, including <strong>STB Provider</strong>, offer MetaTrader 5, traders benefit from consistent order execution, transparent pricing, and access to the broker’s full range of 500+ instruments under the same familiar interface.</p>

<h2>Example</h2>
<p>A trader opens a long position on EUR/USD at 1.0850 with a volume of 1.0 lot (100,000 EUR). They attach an Expert Advisor that implements a 20‑pip trailing stop. The EA monitors the trade; when the price reaches 1.0870, the stop loss moves from 1.0830 to 1.0850. If the price later rises to 1.0900, the stop adjusts to 1.0880. Should the market reverse and hit 1.0880, the position closes automatically, locking in a profit of approximately 30 pips, or $300 for a standard lot.</p>
