MT4 vs MT5 for an XAUUSD EA: Which One Should You Actually Run?

The short answer For an XAUUSD EA, both MT4 and MT5 work. The right choice usually comes down to which platform your broker or prop firm offers, not technical superiority. PULSEBOT supports both.

That said, the platforms aren't identical, and the differences matter once real money is on the line.

MT4: still the default for gold EAs MT4 has been the industry standard for over a decade. For a gold EA, that means: - Broker availability. Almost every retail broker and prop firm offers MT4. If a vendor only ships an MT5 EA, you're already filtered out of a chunk of the market. - Mature EA ecosystem. Most published EAs, including older proven gold systems, target MT4 first. - Hedging by default. MT4 uses a hedging account model — useful when you want long and short positions on XAUUSD simultaneously. - Lighter footprint. Lower RAM and CPU usage on a VPS, which matters when you're running multiple instances.

The downside: MT4 is no longer actively developed by MetaQuotes. Some brokers are slowly winding it down.

MT5: better engine, fewer headaches at scale MT5 was rebuilt from scratch and is the platform MetaQuotes actively maintains. - Faster strategy tester. Multi-threaded backtesting with real tick data — meaningful for tuning XAUUSD EAs that depend on intra-bar behavior. - Netting and hedging modes. Most retail brokers expose hedging mode, but check before assuming. - More instruments and timeframes. Native support for things MT4 only does via workarounds. - Better order types. Stop-limit orders and partial fills are first-class.

The downside: a non-trivial number of brokers and a few prop firms still don't offer MT5 with reasonable XAUUSD conditions.

For prop firm challenges specifically If you're running an EA on a prop firm evaluation, check three things in order: 1. Does the prop firm offer the platform at all? 2. What are the spreads and commissions on XAUUSD on that platform? 3. Does the EA you want to run (e.g. a prop firm EA) support that platform?

Don't let platform preference dictate broker choice — let broker conditions and prop firm support dictate platform.

What to ignore - "MT5 is the future." Maybe. The relevant question is what works *today*. - "MT4 is dead." It isn't. Gold EAs still execute on MT4 at most brokers worldwide. - Marketing claims about platform-specific edge. The edge is in the strategy and risk model, not the platform.

Bottom line Pick the platform your broker or prop firm gives you the best XAUUSD conditions on, then pick an EA that runs on both. PULSEBOT runs on MT4 and MT5 — see the XAUUSD EA page for setup details, or the prop firm EA page if you're running an evaluation.
