Full Definition
MetaTrader is the world's most widely used retail forex trading platform, developed by MetaQuotes Software. The two main versions, MetaTrader 4 (MT4) and MetaTrader 5 (MT5), support automated trading via Expert Advisors, custom indicators, comprehensive charting tools, and one-click order execution. MetaTrader is offered by thousands of forex brokers globally, making it the de facto standard for retail traders.
MT4 was released in 2005 and remains popular for its simplicity, stability, and the massive library of third-party EAs and indicators available in the MQL4 language. MT5 was released in 2010 with expanded capabilities including more timeframes (21 vs 9), more order types, depth of market (DOM) display, built-in economic calendar, multi-asset trading (stocks, futures), and a faster strategy tester. MT5 uses MQL5 which is more powerful but less backward-compatible than MQL4. Both platforms run on desktop, web, and mobile.
For example, a trader on MT4 can open a chart of EUR/USD, drag an EA onto it, and the EA begins executing the coded strategy automatically. The terminal shows trade history, account balance, equity, margin, and P&L in real time. A subscriber running a copy trading signal through MT4 or MT5 has every trade from the master account appear on their chart with the original stop loss and take profit levels, scaled to their account size.
In copy trading, MetaTrader is the standard environment for executing signals. SteadyFlowFX works with MT4 and MT5 accounts at supported brokers, allowing subscribers to connect and receive the 9 algorithms trading 8 currency pairs automatically. The verified Myfxbook 71.3 percent win rate and 1.73 profit factor are reproducible on subscriber MetaTrader accounts as long as the broker offers comparable spreads and execution. Understanding MetaTrader helps subscribers set up their platform correctly and verify that copied trades appear exactly as expected.
