Can I run the same gold EA on both MT4 and MT5?

Not directly — MQL4 and MQL5 are different programming languages and an EA written for one cannot run on the other without recompilation or rewriting. Some EA developers provide both MT4 and MT5 versions of their software (requiring separate purchases or both included in one license). If you have an MT4 gold EA you want to use on MT5, you need either the developer to provide an MT5 version or a qualified developer to port the EA code. Attempting to copy MT4 EA files into an MT5 Experts folder will not work.

Which broker should I use for MT5 gold trading?

The key criteria for a gold EA broker on MT5: raw spread account (spread on XAUUSD under 15 pips during London session), fast ECN execution (under 30ms order execution time), EA trading explicitly permitted (no restriction on scalping or automated trading), and MT5 account type with hedging enabled. IC Markets, Pepperstone, Tickmill, and FP Markets are commonly used by automated gold traders for these reasons. Verify current spreads and EA policy directly with any broker before funding, as these can change.

What happens to my XAUUSD EA if I switch brokers from MT4 to MT5?

Switching brokers means: (1) You need an MT5-compatible version of your EA — the MT4 version will not work. (2) You need to reconfigure EA parameters for the new broker's XAUUSD symbol name, spread, and point value. (3) Your EA's historical performance data on the old broker does not transfer — you are starting a new track record. (4) You should run on demo at the new broker for 2–4 weeks before going live, to confirm the EA behaves as expected under the new broker's execution model.

Does MT5 have better gold spreads than MT4?

Spreads are a function of broker selection, not platform choice. The same broker typically offers similar spreads on their MT4 and MT5 accounts. However, some brokers offer tighter spreads on their MT5 raw accounts as an incentive to migrate. The key is to compare the specific account type (raw/ECN spread) at your specific broker on both platforms. Do not assume MT5 automatically means better spreads — verify with your broker.

Can I backtest my gold strategy on MT4 if I plan to trade it live on MT5?

Not reliably. MT4 and MT5 process orders differently, and the tick data quality difference (90% vs 99%) means that a backtest on MT4 will produce different results than the same strategy would produce on MT5 live. The recommended approach: if you plan to trade on MT5, backtest on MT5 using native tick data. The MT5 strategy tester is more capable than MT4 for this purpose, including multi-currency portfolio backtesting and higher accuracy for gold strategies.

Is MT4 being discontinued for gold trading?

MetaQuotes (the developer of MetaTrader) officially stopped selling MetaTrader 4 licenses to new brokers in 2022. Existing MT4 brokers can continue offering it, but no new brokers can add MT4. This means over time, MT4 availability will decline as brokers shift to MT5. For gold traders, this creates a planning horizon: EAs built exclusively for MT4 will eventually face platform availability risk. Building a track record on MT5 now is the forward-looking choice.

What is the one good reason to stay on MT4 for gold trading?

The only legitimate reason to stay on MT4 is if you have a proven, currently profitable gold EA that runs only on MT4 and has no MT5 equivalent planned by the developer. In this specific scenario, switching platforms means losing the EA that is generating returns. The correct approach: continue trading on MT4 while searching for an MT5 equivalent or waiting for the developer to port the EA. Do not switch platforms arbitrarily if you have a working, profitable system — disruption has a cost.

Platform Comparison

MT4 vs MT5 for Gold Trading:
The 8 Differences That Actually Matter

The general MT4 vs MT5 debate is well-documented. This is the gold-specific version: how each platform handles XAUUSD symbol quality, tick data for backtesting, hedging mode for gold EAs, and the shifting ecosystem of gold EA development. Eight criteria, gold-focused analysis.

The full MT4 vs MT5 comparison across all features is in our MT4 vs MT5 comparison guide. XAUUSD symbol naming issues are covered separately in our MT5 gold setup guide.

Should You Switch to MT5 for Gold Trading?

Answer 5 questions to get a specific recommendation for your situation.

MT4 may be sufficient for your specific use case

If you are not using a gold EA, do not need high-quality backtests, and are not hedging — MT4's differences may not materially affect your results. However, as new gold EAs increasingly require MT5, reassess this annually.

Why the MT4 vs MT5 Debate Matters More for Gold Than Other Instruments

Gold traders are more affected by platform differences than most currency pair traders. The reasons are specific to XAUUSD's characteristics. First, gold's higher volatility makes tick data quality more impactful — a 10-pip interpolation error on EUR/USD backtests is minor; on XAUUSD where 10-pip moves occur multiple times per session, the cumulative impact on backtest accuracy is significant. Second, gold EAs tend to be higher-frequency (5–15 trades/day for session-breakout strategies), meaning execution quality differences compound across many more events per session than a swing trading EA would face.

Third, gold's news sensitivity is exceptional among liquid instruments. Fed meetings, CPI releases, and geopolitical events create intraday moves that are difficult to filter without the MT5 built-in economic calendar. Fourth, the gold EA development ecosystem has shifted toward MT5 more aggressively than for forex pairs — in part because the tick data quality advantage makes strategy validation more reliable on MT5, which gives MT5-developed gold EAs a higher credibility floor.

Backtest quality requirements for gold EAs specifically are explained in our backtest quality guide.

The Backtest Quality Gap in Practice

What does the difference between 90% and 99% modelling quality mean in a 2,000-trade gold backtest? Approximately 200 trades in the MT4 90% backtest are simulated using interpolated tick data rather than real historical ticks. These are not randomly distributed — interpolated ticks cluster around periods of thin data, which in XAUUSD means Asian session lows, major news events, and session transitions.

A gold scalping EA that captures London and New York session opens — where volatile, directional moves occur frequently — is precisely the type of strategy most affected by interpolated tick quality. The EA's most important trades (high-volatility, session-open momentum) are the ones where MT4's interpolation introduces the most error.

Practical example: 2,000-trade gold scalping EA backtest

MT4 — 90% Modelling

~200 trades on interpolated ticks
Session-open entries may show unrealistic fills
News-period SL hits may be underrepresented
Backtest profit: likely overstated by 5–15%

MT5 — 99% Tick Data

All 2,000 trades on real historical ticks
Session-open entry/exit simulation accurate
Slippage on volatile ticks properly modelled
Backtest profit: reliable basis for strategy decision

The XAUUSD Naming Convention Map by Broker

Before configuring any gold EA, verify your broker's exact XAUUSD symbol name in MetaTrader's Market Watch (Ctrl+U to add symbols). This is not optional — the wrong symbol name in your EA's parameters means zero trades will execute.

Symbol Name	Typical Brokers	Platform
XAUUSD	IC Markets, Pepperstone, Tickmill, FP Markets	MT4 & MT5
GOLD	Exness, XM, HFM on some account types	MT4 & MT5
XAUUSD.m	Smaller or rebranded ECN brokers	MT4
GOLDm	Some FBS, HotForex account types	MT4
XAUUSDpro	IC Markets Pro accounts in some regions	MT4/MT5
GOLD.cash	Some CFD brokers differentiating spot from futures	MT4 & MT5

This table is indicative — always verify your broker's current symbol name before live trading. Brokers can change symbol conventions following platform migrations or account type restructuring.

How to Migrate from MT4 to MT5 with Your Gold EA

Migrating your gold EA operation from MT4 to MT5 is a structured process. Attempting it without the right sequence creates unnecessary disruption to a potentially working system.

1

Get the MT5 version of your EA

Contact your EA developer. If they have an MT5 version, request it — some licenses are platform-agnostic, others require a separate purchase. Do not attempt to run MT4 EA files on MT5.

2

Select and open MT5 account at your broker

Most established gold brokers (IC Markets, Pepperstone, Tickmill) offer both MT4 and MT5 accounts. Open a new MT5 raw account — do not close your MT4 account until the migration is complete.

3

Set up VPS for MT5

If you are running your EA on a VPS, confirm your VPS provider supports MT5. Most do, but the installation and configuration process differs slightly from MT4.

4

Reconfigure EA parameters for MT5 and new broker

Symbol name, point value, and spread-dependent parameters may all need adjustment. Run the EA in Strategy Tester on MT5 with real tick data to confirm parameters produce expected results.

5

Run demo on MT5 for 2–4 weeks

Before committing live capital, run on MT5 demo at the new broker to verify trade frequency, SL/TP execution, and EA stability match expectations from MT4 operation.

6

Parallel operation briefly (optional)

If capital allows, run both platforms simultaneously for 2 weeks with conservative lot sizes. This gives direct comparison data and identifies any MT5-specific parameter adjustments needed.
