MetaTrader 4 (MT4) Review

MetaTrader 4 (MT4) is a third-party trading platform built by MetaQuotes Software and released in 2005. It was designed for retail forex and quickly became the industry standard — to this day it is the single most widely offered platform among retail brokers, supported by more brokers than any competitor.

MT4's staying power comes from three things: a remarkably stable charting engine, a low hardware footprint that runs on almost anything, and MQL4 — the scripting language that spawned the largest ecosystem of Expert Advisors (automated trading robots) and custom indicators in retail trading. If a strategy has been coded for retail, the odds are it exists for MT4.

It is not the most modern platform. It was built before multi-asset trading and depth-of-market became standard expectations, and MetaQuotes itself now positions MT5 as the successor. But for a forex-focused trader who wants automation, a huge community library and a broker that almost certainly supports it, MT4 remains a defensible — and often optimal — choice.

• Expert Advisors (EAs): fully automated trading robots written in MQL4, running 24/5 on your charts.
• Custom indicators & scripts: thousands of free and paid tools via the built-in Market and Code Base.
• Nine timeframes and 30+ built-in technical indicators with a clean, fast charting engine.
• One-click trading and a built-in strategy tester for backtesting EAs on historical data.
• Cross-device sync: Windows, macOS (via web), web terminal and full-featured iOS/Android apps.

MT4 uses an instant- and market-execution model with four pending order types: buy limit, sell limit, buy stop and sell stop. It runs a hedging position model, so you can hold simultaneous opposing positions on the same symbol — useful for certain grid and hedging strategies that MT5's netting mode restricts.

Charting offers nine fixed timeframes (M1 to MN) and more than 30 built-in indicators, with unlimited charts open at once. The platform's weaknesses for power users — a single-threaded strategy tester and no native Level 2 depth-of-market — were precisely the gaps MetaQuotes set out to close in MT5. In exchange, MT4 gives you the deepest third-party tool ecosystem on the market.

Automation is MT4's signature strength. Expert Advisors are coded in MQL4 and run unattended on your charts, executing entries, exits and risk rules without you at the screen. The MetaTrader Market and Code Base give you instant access to thousands of EAs, custom indicators and scripts — free and paid — directly inside the terminal.

The built-in Strategy Tester lets you backtest an EA against historical price data before risking capital, and the MQL4 community remains one of the largest developer ecosystems in retail trading. For copy-trading, many brokers layer MT4 with MetaTrader Signals or third-party social platforms.

MT4 runs natively on Windows, in any browser via the web terminal, and on iOS and Android through full-featured mobile apps that sync positions and charts in real time. macOS users typically run it through the web terminal or a broker-supplied build. Its low hardware requirements mean it runs smoothly even on older machines and VPS hosting — the standard setup for running EAs around the clock.

Because MT4 is so widely supported, your choice should come down to the broker's spreads, execution quality and regulation rather than the platform itself. Look for tight raw spreads, fast fills and tier-1 regulation (FCA, ASIC, CySEC). Many top brokers offer MT4 alongside MT5 or cTrader, so you can test the platform on a demo before committing real capital.
