MetaTrader 4

The standard thatdefined the industry.

Two decades on, MT4 remains the most widely deployed retail trading terminal on earth — and the ecosystem is the reason. Thirty built-in indicators and twenty-three analytical objects cover the charting essentials; thousands of community EAs, scripts and custom indicators cover everything else.

The Ecosystem

Experience,as infrastructure.

The signals marketplace turns experience into infrastructure: subscribe to a provider and your terminal mirrors their trades automatically, with your own risk caps layered on top. For many clients, that is the whole strategy — and it works from day one.

Everything runs against the same aggregated Tier 1 book as MT5 — the classic terminal loses nothing on execution.

FAQ

Good questions,straight answers.

MT4 or MT5 — which should I pick?

New to MetaTrader? Start with MT5 — more timeframes, better tester, active development. Deep in the MT4 ecosystem with EAs you trust? Stay; MQL4 code does not run on MT5 unmodified, and stability beats novelty.

Can I use one login across all platforms?

Your trading account credentials work across MT4/MT5 desktop, mobile and WebTrader simultaneously. The IEXS app adds client-portal functions on the same identity.

Do EAs keep running when my computer is off?

No — EAs live in the terminal, and the terminal must be running. Serious automation runs on a VPS near the venue so the terminal stays online around the clock.

Will my MQL4 EAs run on MT5?

Not unmodified — MQL4 and MQL5 are different languages. If your EA portfolio is proven on MT4, staying is a perfectly good decision.
