MT4 vs MT5: Which MetaTrader Platform Should You Use?

MT4 and MT5 differ in order types, account modes, timeframes, and tools — this guide breaks down what actually matters for forex and gold traders choosing between them.

If you're weighing up MT4 vs MT5, the honest answer is that it depends on what you trade and how you want your positions managed. MT4 is the older, simpler platform, still widely used in forex because of its hedging support and its long-established library of Expert Advisors. MT5 is the newer platform, built with more timeframes, deeper market data, and multi-asset flexibility, including gold, indices, and futures alongside forex.

Both platforms are made by MetaQuotes and look similar at first glance, which is exactly why so many traders get caught out switching between them. The differences aren't cosmetic. They affect how your trades execute, how opposing positions net against each other, what data you can see on a gold chart during a volatile session, and whether the Expert Advisor your signal provider built will even open on your terminal. This article works through each of those differences on its own terms, then applies them to forex and gold trading specifically.

None of this is about one platform being universally better. It's about matching the platform's mechanics to how you actually trade — and remembering that trading either one carries the same underlying risk of loss, because the platform itself doesn't change the market.

MT4 vs MT5 at a Glance

Before going into the mechanics, here's the comparison stripped down to what actually changes your day-to-day trading.

The rest of this article unpacks each row, because the table alone doesn't tell you which one suits your trading.

Order Types: What's Different Between MT4 and MT5

MT4 gives you four pending order types: Buy Limit, Sell Limit, Buy Stop, and Sell Stop. That's been enough for most retail forex strategies for years, and it's still the baseline most MT4 EAs are built around.

MT5 expands this to six by adding Buy Stop Limit and Sell Stop Limit — orders that place a limit order once price touches a stop level first. That's useful if you want a limit entry but only after confirming a breakout direction, rather than being filled the instant a stop level is hit.

MT5 also introduces order filling policies that MT4 doesn't have natively:

• Fill or Kill (FOK): the entire order must be filled at the requested volume, or it's cancelled outright.
• Immediate or Cancel (IOC): as much of the order as possible fills immediately at the available price, and any unfilled remainder is cancelled rather than queued.

For most manual forex traders, these distinctions won't change much day to day. For anyone running EAs where partial fills or slippage on size matter, MT5's filling policies give more explicit control over what happens when liquidity is thin — a scenario that tends to come up more on gold and less liquid pairs than on EURUSD.

Hedging vs Netting Accounts

This is the difference that trips up more traders switching platforms than anything else. Hedging vs netting on MetaTrader determines what happens when you open opposing positions on the same symbol.

Take a concrete scenario: you open a long EURUSD position, then later open a short EURUSD position, without closing the first one.

• On an MT4 hedging account, both positions sit independently in your terminal. You'll see two separate trades — one long, one short — each with its own entry price, stop loss, and take profit. Your net exposure is effectively flat, but you're carrying spread and potentially swap on both legs, and you can manage each one separately.
• On an MT5 netting account, the platform automatically combines them. The short order closes some or all of the long position first, and whatever remains becomes a single net position. You won't see two open trades — you'll see one, reflecting your net exposure.

MT4 only supports hedging. MT5 supports both hedging and netting, but which one you get depends on your broker and account type. If your strategy relies on deliberately holding opposing positions — grid systems, certain correlation trades, or specific EA logic — confirm your account mode before you trade, not after.

Timeframes and Charting Tools

MT4 gives you nine timeframes: M1, M5, M15, M30, H1, H4, D1, W1, and MN1. That's been sufficient for most strategies for close to two decades, and plenty of traders never feel the gap.

MT5 expands this to 21 timeframes, filling in the gaps with options such as M2, M3, M4, M6, M10, M12, M20, H2, H3, H6, H8, and H12. If your strategy is tuned to a specific interval — say a 20-minute breakout filter or a 3-hour trend read — MT5 lets you view that timeframe natively instead of approximating it by eye on a chart that doesn't quite match.

MT5 also includes a built-in Depth of Market (DOM) tool, showing the volume sitting at different price levels for a symbol. MT4 has no equivalent natively. DOM is most useful on instruments where you want a read on immediate buying and selling pressure rather than just the last traded price — which matters more for gold than for a major forex pair, given how quickly gold's liquidity can shift during volatile sessions.

Programming Language and Strategy Testing

MT4 runs on MQL4, MT5 on MQL5. They look similar but aren't interchangeable — code written for one won't compile or run on the other without being rewritten, which is the root of most EA and copy-trading compatibility questions.

The bigger practical difference sits in the Strategy Tester. Say you've built an EA that trades three currency pairs at once, using signals from one pair to time entries on another. In MT5's Strategy Tester, you can backtest that EA across multiple symbols within a single test run, because MT5 supports multi-symbol backtesting natively.

MT4 can't do this in the same way. Its Strategy Tester is built around testing one symbol at a time. If your EA logic depends on reading correlated pairs together, you either accept an incomplete backtest on MT4 or rebuild and test the logic on MT5 instead.

For traders who only backtest single-pair strategies, this gap won't matter much. For anyone building or buying EAs with cross-pair logic — including some gold-correlated systems that reference a proxy symbol for the dollar or yields — MT5's testing environment reflects that behaviour more accurately.

Symbols and Market Data

MT5's Market Watch window goes further than MT4's, offering a fuller depth-of-market view per symbol where your broker supports it, on top of the standard bid/ask ladder and the DOM tool already mentioned for individual charts.

MT5 also includes a built-in economic calendar tab directly in the terminal. You can see upcoming data releases and previous readings without leaving the platform. MT4 has no native equivalent — traders using MT4 typically rely on an external calendar or a signal provider's alerts to stay ahead of scheduled news.

For a forex trader watching for a central bank decision, having the calendar inside the same window as open positions removes one extra tab to check. For a gold trader, the same calendar matters just as much, since gold tends to react sharply to US inflation data and central bank commentary.

EA and Copy Trading Compatibility

This is where the MQL4/MQL5 split becomes a practical problem rather than a technical footnote. An EA compiled for MT4 will not run on MT5, and an EA compiled for MT5 will not run on MT4. They are separate files, built on separate language versions, with no built-in converter that reliably turns one into the other.

This matters directly for copy trading. Say you follow a Telegram signal provider and want to copy their calls to your live account. If that provider only distributes an MT4-compatible setup, and your account happens to be MT5, the file simply won't open — it isn't a settings issue, it's an incompatible platform.

The practical fix is running separate setups per platform rather than expecting one to serve both. This is the kind of split MarketSync is built to handle: it supports copying signals to both MT4 and MT5 accounts, but each connected account is designated as one or the other, not both at once. When you connect an account, you choose MT4 or MT5 explicitly, then select your broker server and enter the account number and trading password — the investor password won't work, since copying trades requires the account's full trading password. Because the same signal source in MarketSync's library can be attached to multiple accounts, a trader who wants the same signals mirrored onto both an MT4 and an MT5 account can set that up with independent settings on each, rather than having to pick one platform for that signal provider.

Which Platform Is Better for Forex Trading

For forex specifically, the decision usually comes down to how you manage positions and how many pairs you're watching.

Consider a EURUSD scalper who regularly opens partial hedges — a small opposing position to manage risk mid-trade while waiting for a level to hold or break. That style depends on the platform showing both positions independently rather than netting them together, which points towards an MT4 hedging account, since hedging is available there regardless of broker.

Now consider a multi-pair swing trader running positions across several currency pairs, holding for days, and timing entries around scheduled data releases. That trader benefits more from MT5's expanded timeframe set for fine-tuning entries, and from having the economic calendar built into the same window as open trades. Multi-symbol backtesting matters more here too, since swing strategies often factor in correlation between pairs.

Neither approach is objectively correct. The scalper's hedging need and the swing trader's data need are genuinely different requirements, and MT4 or MT5 for forex trading should follow from which one you actually are.

Which Platform Is Better for Gold Trading

Gold tends to behave differently to most forex pairs — moves can sharpen quickly around scheduled US data, and liquidity can thin out during the handover between trading sessions. That makes MT5's extra tools more relevant for gold trading than they might be for a calmer forex pair.

Picture a gold trader watching XAUUSD through a session with a major US data release due. MT5's Depth of Market gives a live read on where buy and sell volume is sitting as the figure drops, which is useful precisely because gold's price can shift rapidly in that window. The additional timeframes matter too — a trader who normally works off H1 and H4 charts might want to check an H2 or H3 view specifically to filter noise during that volatility, an option MT4 doesn't offer.

The built-in economic calendar reinforces this. Trading gold around scheduled US data benefits from having the release time in the same window as the chart, rather than switching between platform and browser mid-session.

None of this means gold can't be traded on MT4 — plenty of traders do, particularly if their broker or EA is MT4-only. But if you're choosing a platform specifically with gold in mind, MT5's data tools are built for exactly this kind of volatility.

Can You Use MT4 and MT5 at the Same Time

Yes, and it's more common than traders expect. There's no restriction on running both terminals on the same computer, connected to different accounts, at the same time.

A practical example: a trader keeps an MT4 hedging account for their forex trading, where they run a strategy that occasionally opens opposing positions deliberately, and a separate MT5 netting account for gold, where they want the Depth of Market and wider timeframe range. Both terminals run side by side on the same machine, each connected to its own broker account, with no interaction between them.

This is also the setup MarketSync supports on the copy-trading side. Since each connected account is designated as MT4 or MT5 individually, a trader running this exact forex-and-gold split could connect both accounts, attach the same or different signal sources to each, and manage the settings independently — copying a forex signal to the MT4 hedging account and a gold signal to the MT5 netting account, without either setup affecting the other.

Frequently asked questions

Is MT5 replacing MT4?

MT5 is the newer of the two platforms and MetaQuotes has continued developing it, but MT4 remains widely available and heavily used, particularly among forex traders relying on hedging accounts or long-established MT4 EAs. There's no fixed date by which MT4 disappears — that's a decision each broker makes on its own timeline.

Can I convert an existing MT4 account into an MT5 account?

Not directly — MT4 and MT5 accounts are separate account types on separate platforms, even at the same broker. You'd need to open a new MT5 account and transfer funds across, rather than upgrading the existing one in place.

Do all brokers offer both MT4 and MT5?

No. Availability varies by broker, and some offer only one platform or restrict certain account types or instruments to one over the other. Check with your specific broker before assuming both are on offer.

Is MT5 harder to learn than MT4 for a beginner?

The core interface — charts, order panel, Market Watch — is similar enough that most beginners adjust within a session or two. The extra features, like the additional order types and Depth of Market, add options rather than complexity you're forced to use.

Which platform do most prop trading firms support?

This varies by firm and can change, so it's worth checking directly with the specific prop firm rather than assuming either platform is standard. Some support only one, others offer both across different evaluation programmes.

Will my broker eventually stop supporting MT4?

Possibly, but timing depends entirely on the individual broker's plans, not on a fixed cutoff from MetaQuotes. If continuity matters to your strategy, it's worth asking your broker directly rather than assuming either platform's support is guaranteed indefinitely.

Deciding and moving forward

The choice between MT4 and MT5 comes down to three questions: do you need hedging or are you fine with netting, do you need the extra timeframes and data tools MT5 offers, and is your EA or signal provider built for one platform specifically. Answer those honestly against how you actually trade forex or gold, rather than picking whichever platform seems newer or more commonly used.

Once you've settled on a platform, connecting it to a copy trading setup is a separate, later step — and one where MarketSync lets you attach signal sources to whichever account type you've chosen, MT4 or MT5, using that account's trading password, with the option to run both platforms side by side under independent settings if your trading actually calls for it.
