MetaTrader 4 vs MetaTrader 5 - What Is Actually Different

The Misunderstanding in the Name

The numbering suggests MT5 replaces MT4 the way version 5 of an app replaces version 4. It does not, and that is the single most useful thing to know about the comparison.

They are separate products. MT5 was written in a different language (MQL5 rather than MQL4), so nothing built for MT4 runs on it - not an indicator, not an expert advisor, not a script. Every tool has to be rewritten, and eighteen years of MT4 tools mostly never were.

That is the actual reason MT4 survived a replacement that arrived in 2010: the ecosystem could not move, so it stayed.

What Is Identical

For everything a beginner does, the two platforms are the same program with a different colour scheme:

• Charting, timeframes, drawing tools, indicators.
• Placing market, limit and stop orders; setting stop-loss and take-profit.
• The four account figures - balance, equity, margin, free margin.
• One-click trading, the trade history, exporting statements.
• Running an expert advisor, once it is written for that platform.

If you learn to trade on one, you can use the other the same afternoon. Nothing conceptual differs.

Where They Genuinely Differ

• Asset coverage - MT5 handles stocks and futures with real exchange depth; MT4 was built for forex and CFDs and stays there.
• Timeframes - 21 in MT5 against 9 in MT4. In practice most traders use four of them.
• Order types - MT5 adds buy stop limit and sell stop limit. Useful for a narrow set of strategies, irrelevant to most.
• The strategy tester - MT5 tests multiple instruments at once and uses all your processor cores. For anyone building automated systems this is the one difference that genuinely matters.
• Hedging - MT4 always allowed opposite positions on the same instrument. MT5 originally did not; it was added later, but which mode you get depends on the broker's account type.
• The economic calendar is built into MT5 and absent from MT4.

The One That Catches People Out

US-regulated brokers require FIFO - first in, first out - meaning if you have two open positions on the same pair, you must close the older one first. MT5's netting mode enforces this natively; MT4's hedging model does not.

This is not a quality difference. It is a regulatory model, and it is the reason some brokers offer only one of the two platforms rather than both.

Which to Choose

If you are trading forex, gold and crypto, and especially if you want the large existing library of indicators and expert advisors, MT4 is still the practical default.

If you want stocks or futures in the same terminal, or you are going to build and backtest automated strategies seriously, MT5.

And if you are starting: use whichever your broker supports best. The platform is not what determines your result. Position size is - and both platforms compute it identically.

Which Runs This Site

MT4. The account here is forex, gold and crypto, the expert advisor that publishes every trade to this site is written in MQL4, and the platform has run without interruption for years. Stability on a live account outweighs a longer feature list.
