Broker MT4 : cadre de sélection pour 2026

An MT4 broker is a regulated firm that offers MetaTrader 4 as its primary trading terminal. The platform was released in 2005 by MetaQuotes Software Corp, has not been formally end-of-lifed despite the existence of MT5 since 2010, and remains the dominant retail platform in several regions because of its enormous expert advisor library and its lighter resource footprint. Choosing an MT4 broker in 2026 is not about platform availability (most brokers still offer it). It is about getting the version of the broker that gives you a desk-grade execution stack on top of a maturing platform.

Why traders still pick MT4 in 2026

Three persistent reasons:

• Legacy expert advisor library. Twenty years of community-built EAs and indicators in MQL4. Many never got ported to MT5. If your strategy depends on a specific EA, MT4 is non-negotiable.
• Lower hardware demand. MT4 runs cleanly on a 4GB Windows VPS. MT5 prefers 8GB. For copy traders and EA operators running 5-10 concurrent terminals, the cost difference is real.
• Familiarity. A trader with five years of muscle memory on MT4 templates and shortcuts loses two months of productivity switching to MT5 mid-career.

The selection framework

Eight points, in priority order:

1. Regulator and verifiable licence

Tier-1 European licence (CySEC, BaFin, FCA, AMF, etc.) is the floor for an EU retail trader. Open the regulator’s register and confirm the entity name and licence number match. CySEC’s register at cysec.gov.cy. Licence numbers are unique and the register lists permitted services.

2. Execution model

STP, ECN, or market maker. The broker should disclose the model in its order-execution policy under MiFID II. STP and ECN brokers route to external liquidity; market makers internalise flow. None of the three is automatically better; what matters is that the model is disclosed and matches your strategy.

3. EA hosting and concurrent EA limits

If you run EAs, two specifics:

• Does the broker offer or partner with a VPS service? MetaQuotes’ VPS runs $10-20 per month and is configurable from the MT4 terminal.
• Does the broker cap concurrent EAs per account? Some brokers throttle or block specific EA categories (martingale, news scalpers).

4. Spreads at the moment that matters

Marketing spreads are mid-of-day, low-volatility numbers. The spreads that matter are at session open, news release, and overnight rollover. Demo for a week and watch EUR/USD at 09:00 London, 14:30 London, and 22:00 server time. Tier-1 desks should hold 0.6-1.2 pips during liquid hours.

5. Commission structure

Standard accounts: zero commission, spread-only. Raw or ECN accounts: tight spreads plus $3-7 round-turn per lot commission. Compute the all-in cost on your typical trade and compare.

6. Swap rates aligned to your hold horizon

If you carry overnight, swap is a real cost. Brokers publish per-symbol swap rates. Triple-swap on Wednesday for FX is standard. Build a 30-symbol comparison spreadsheet across your top three brokers; the cheapest broker on EUR/USD long is rarely the cheapest on USD/JPY short.

7. Withdrawal speed with a published target

Time from request to bank credit, on the rail you actually use. SEPA in EUR should clear in 4-24 hours after broker approval. Card refunds in 1-5 business days. Brokers that quote 5-10 business days as standard are an unnecessary working-capital problem.

8. Negative balance protection

Mandatory for EU retail under ESMA. The clause should appear explicitly in the client agreement, capping loss at cash funded.

What MT4-specific features the broker has to enable

• One-click trading. Available on MT4 by default; some brokers gate it behind KYC tier.
• Hedging. MT4 only supports hedging accounts (not netting), but the broker still has to enable simultaneous opposite positions on the same symbol.
• Custom symbols and indicators. The broker controls which symbols are available and whether custom indicators load. Test your favourites in the demo.
• Mobile build. MT4 mobile (iOS/Android) is identical across brokers from a code perspective, but server connection and push notifications depend on the broker’s MT4 server config.

The end-of-life question

MetaQuotes stopped issuing new MT4 licences to brokers in 2018, but existing licences continue and the platform receives security updates. Many brokers still offer MT4 in 2026 alongside MT5; the platform is not deprecated for end users. The trajectory is gradual migration, not a cliff. A broker that still actively supports MT4 in 2026 is making a deliberate commitment to the legacy user base, which is information about how that broker treats its existing clients.

The shortlist test

Three to four candidate brokers, demo for two weeks, then live trial with the smallest viable funding for two more weeks. Measure four things: average fill speed, slippage skew, spread widening at session change, and time from withdrawal request to bank credit. The broker that wins on all four is your broker.

Common traps in 2026

• « MT4 with 1:500 leverage » offered to EU retail. Almost certainly routed through an offshore entity. EU regulatory protection does not apply to those funds.
• Bonus offers with EA restrictions in the small print. A broker that bans EAs from bonus accounts is telling you the bonus is not designed for serious traders.
• « Floating spreads from 0.0 » with hidden minimums. Fixed minimum spread plus markup is a common pattern. Read the spec sheet, not the headline.
