Search "MT4 vs MT5" and you'll drown in trader-facing comparisons: timeframes, order types, backtesting speed. All true, all beside the point if you're the one launching a firm. The owner's question isn't "which terminal would I rather trade on?" — it's "which platform can I actually get, what does its ecosystem cost me monthly, who runs its servers, and will its vendor still want my business next year?" On those questions, the two platforms differ far more than any feature table suggests.
Here is the honest owner's comparison — MT4's real strengths included, MT5's real burdens included, and the 2026 context both now sit inside.
The Technical Difference, in Two Paragraphs
MT4 (2005) is a forex-first platform: MQL4 programming, order-based hedging accounting, nine timeframes, a lean terminal that an enormous ecosystem of expert advisors (EAs) and custom indicators grew around. Its architecture reflects its era — and its immortality comes from that ecosystem: two decades of bots, indicators and muscle memory that traders don't want to abandon.
MT5 (2010) is what MetaQuotes built to replace it: a multi-asset platform with both netting and hedging modes, MQL5, 21 timeframes, depth of market, exchange-traded instrument support and a much faster multi-threaded strategy tester. It is technically superior on nearly every axis — and it broke backward compatibility with MQL4, which is why adoption took a decade and why MT4 refused to die on schedule. MetaQuotes settled the argument commercially instead: new MT4 server licences stopped being issued years ago. The future of MetaTrader is MT5, by decree as much as by merit.
The Owner's Five Questions
1. Can I Even Get It?
MT5: yes, via a licence (a six-figure commitment as commonly cited) or a white label from an existing holder. MT4: only as a white-label sublet of an aging licence pool — you're renting scarcity, with the dependency chain that implies. Details in the MT4 white-label guide.
2. What Does the Ecosystem Cost Monthly?
Structurally identical, and structurally expensive: platform fee + market data + bridges/gateways + plugins + hosting + administration + a separate CRM. MT5's gateways multiply with multi-asset ambitions; MT4's plugin economy is mature but built on maintenance-mode software. Neither includes the business layer — portal, KYC, payments — that a firm actually runs on.
3. Who Runs the Servers?
You, or your white-label provider, with the gaps between their SLA and your incidents landing on you. Both platforms are installed-server products requiring real administration — updates, monitoring, backups, security patching. This is the invisible full-time job of the white-label model, and it exists on both sides of this comparison equally.
4. Does the Vendor Want My Business?
If you're a licensed broker: yes, on MT5 — that's the franchise MetaQuotes is building. If you're a prop firm: no, on either. The 2024 crackdown — white-label terminations, refused prop setups — applied to the MetaTrader estate, not one version of it. For evaluation firms this question ends the comparison before features begin; the full account is in MetaTrader and prop firms.
5. What's My Migration Cost Later?
MT4 to MT5 is itself a migration — MQL4 code doesn't run on MT5, workspaces don't transfer, and trader retraining is real. That's worth internalising: choosing MT4 today means choosing a future forced migration on top of everything else.
| MT4 | MT5 | |
|---|---|---|
| New licences | No longer issued | Available |
| Development status | Maintenance mode | Actively developed |
| Assets | Forex/CFD-centric | Multi-asset, exchange support |
| Accounting | Hedging only | Netting and hedging |
| Ecosystem | Vast legacy EA/indicator base | Growing, incompatible with MQL4 |
| Prop firms | Closed since 2024 | Closed since 2024 |
| Server admin | Yours | Yours |
The honest verdict: if the question is "MT4 or MT5?", the answer is MT5 — newer architecture, active development, licences you can actually obtain. But notice what the question smuggles in: that you must run an installed, self-administered, separately-fed MetaQuotes server at all. In 2026, that premise is the thing to challenge.
The Question Behind the Question
Both MetaTrader options share every burden that defines the legacy model: an installed terminal in your onboarding funnel, a server estate someone must administer, market data contracted separately, a CRM bought elsewhere and integrated by hand, and a vendor relationship in which policy flows one way. The platforms differ in age; the model is identical — and the model is what firms are actually leaving.
eTrader represents the other model: web-native (traders open a link — no installer, on web, desktop, mobile web and native iOS/Android apps with one synced account), the 70ms-updated data feed included free, hosting fully managed on clustered servers, and published pricing from $6,600/month for brokers and $3,300/month for prop firms plus $1.50 per-account fees. The direct matchups are drawn in eTrader vs MT4 and eTrader vs MT5.
And because the Singuard CRMs bridge to both MT4 and MT5 in 1 click — alongside cTrader, DXtrade, NinjaTrader, Match-Trader and TradeLocker — the choice isn't even exclusive: firms with existing MetaTrader estates or MetaTrader-loyal traders run them through the same CRM, same rules, same operations, while building their owned core on a platform whose economics and vendor incentives point their way.
"MT4 versus MT5 is a 2010 question. Answer it if you must — but ask the 2026 question too: why install anything at all?"

Key Takeaways
- For traders the MT4/MT5 debate is features; for owners it's availability, cost structure, admin burden and vendor policy.
- Between the two, MT5 wins: active development, obtainable licences, multi-asset architecture. MT4 is a rented slice of a frozen pool.
- For prop firms, neither is open — MetaQuotes closed prop setups across the estate in 2024.
- The sharper 2026 question is the model itself: installed and self-administered vs web-native and managed — and bridges mean you don't have to answer exclusively.
Frequently Asked Questions
Is MT4 Still Viable for a New Broker In 2026?
It's obtainable via white label and traders still know it, but you'd be building on unissued licences, maintenance-mode software and a guaranteed future migration. If MetaTrader is essential, start on MT5; if it isn't, start on a modern managed platform and bridge to MetaTrader where demand justifies it.
Will My Traders' MT4 EAs Work on MT5?
Not directly — MQL4 and MQL5 are incompatible, so EAs must be rewritten or replaced. That switching cost is why MT4 survived so long, and it's a cost your firm inherits whichever MetaTrader you standardise on later.
Can I Run MT4 and MT5 Side by Side Under One CRM?
Yes — the Singuard Broker CRM and Prop Firm CRM bridge to both in 1 click, with live and demo accounts routed automatically and identical operations across platforms — eTrader included alongside, never a lock-in.
