MetaTrader 4 was first released in 2005, and more than two decades later it remains the most widely installed retail forex trading platform in the world. Despite the arrival of MT5, the consistent push from MetaQuotes toward their newer platform, and a wave of alternative trading platforms competing for broker attention, MT4 refuses to become irrelevant. For startup brokers evaluating their entry into the market in 2026, the MT4 Grey Label continues to be one of the most rational and commercially sound choices available.
This article explains why MT4's dominance persists, how the grey label model works in practice, and why this combination makes particular sense for brokers launching in retail-heavy markets.
MT4's Global Dominance and Client Familiarity
The numbers are difficult to argue with. Across Asia, the Middle East, Africa, Latin America, and Eastern Europe — the regions where the vast majority of new retail forex broker growth is occurring — MT4 is the platform that traders know, trust, and are already using. When your target client has traded on MT4 for years, asking them to learn a new platform creates friction. Friction kills conversions.
MT4's familiarity is a direct commercial advantage for brokers. Clients can begin trading within minutes of downloading the terminal because the interface is already familiar. Support costs are lower because clients already know how to use the basic functions. Onboarding drop-off rates are measurably better on MT4 than on platforms requiring fresh learning curves.
"The best trading platform for your brokerage is the one your clients already know how to use. In most retail forex markets globally, that platform is still MT4."
The Grey Label Model Explained
An MT4 Grey Label operates on a sublicensing arrangement. A white label holder — a company with a full MetaTrader 4 server licence — grants you branded access to a subset of their server infrastructure. You receive Manager-level access, which allows you to create and manage client accounts, configure spreads, set leverage levels, and monitor trading activity in real time.
Your clients see only your brand. The trading terminal displays your company name, your logo, and your chosen server address. They have no awareness of the underlying infrastructure arrangement. From their perspective, they are trading with your brokerage on your platform.
Cost Advantages of MT4 Grey Label
Cost is often the decisive factor for startup brokers, and the MT4 grey label delivers significant advantages here. When compared to a full MT4 white label, grey label setup costs are typically 70–85% lower. When compared to launching an entirely independent trading platform from scratch, the savings are even more dramatic.
Typical MT4 grey label economics for a startup:
- Setup fee: $1,500 – $5,000 (versus $15,000 – $40,000 for a full white label)
- Monthly cost: $300 – $800 (versus $1,000 – $3,000 for white label infrastructure)
- No liquidity bridge required: Saves $3,000 – $10,000 in setup and $500 – $1,500/month
- No server infrastructure management: The white label provider handles all technical operations
These economics mean a startup broker can be fully operational at a fraction of the cost of traditional white label models, with capital preserved for the marketing and client acquisition activities that actually drive revenue.
Spread Management as Your Primary Revenue Stream
The MT4 grey label revenue model is built on spread markup. Your white label provider delivers pricing at a base spread — for example, 0.6 pips on EUR/USD. You present that to clients at a marked-up spread of, say, 1.4 pips. Every lot your clients trade generates 0.8 pips of revenue to your brokerage.
At meaningful client volumes, this becomes substantial recurring income. The key performance metric for any grey label operator is active client trading volume. Acquiring clients who trade frequently is worth considerably more than acquiring clients who deposit but rarely trade. Your marketing and incentive structures should be designed around encouraging trading activity, not just deposit acquisition.
A-Book and B-Book Routing
Within the grey label framework, sophisticated brokers can configure their client routing strategy — the decision of whether to pass trades to the market (A-book) or internalise them (B-book).
A-Book routing
In an A-book arrangement, client trades are passed through to a liquidity provider. The broker earns the spread markup regardless of whether the client wins or loses on the trade. This model has no conflict of interest and is the preferred approach for regulated brokers. It does require either a bridge connection or routing through the white label provider's liquidity infrastructure.
B-Book routing
In a B-book arrangement, the broker takes the other side of client trades internally. When clients lose, the broker profits beyond the spread. This is a common model for small retail brokers in early stages, particularly when client volumes are too low to attract competitive liquidity pricing. It carries risk — if clients are consistently profitable, the broker absorbs losses — but it is also the model used by a large proportion of the retail forex industry globally.
Most grey label operators start with B-book and transition to hybrid or A-book models as volume and risk management sophistication increases.
Dealer Terminal Features
The MT4 Manager (dealer terminal) that comes with a grey label provides powerful capabilities for day-to-day brokerage operations:
- Real-time monitoring of all open positions across all client accounts
- Manual dealing and requote capabilities for managing execution
- Group-level spread and commission configuration
- Margin call and stop-out level management
- Account balance adjustments for bonuses, corrections, and promotions
- Full trade history export for reporting and reconciliation
- News feed integration for fundamental analysis tools
EA and Algorithmic Trading Support
One of MT4's enduring strengths is its Expert Advisor (EA) ecosystem. There are tens of thousands of freely available and commercially sold MT4 EAs — automated trading scripts that execute strategies without manual intervention. Many retail traders actively seek brokers that support EA trading, and MT4's MQL4 language remains the most widely used algorithmic trading scripting language in retail forex.
By offering an MT4 grey label, you immediately support this entire ecosystem. Algorithmic traders tend to trade higher volumes than discretionary traders, making them commercially attractive clients. Your grey label automatically offers compatibility with every MT4 EA ever built — a feature set that would cost substantial development time to replicate on any proprietary platform.
Steps to Launch an MT4 Grey Label
- Choose a white label provider with a reliable MT4 infrastructure and a clear grey label offering
- Prepare your brand assets — logo, company name, colour scheme, and preferred server domain
- Define your account types — Standard, Micro, ECN — with appropriate spread markups for each
- Select your instrument list — forex majors, minors, metals, indices, and any other assets you intend to offer
- Test the Manager terminal thoroughly before accepting live client accounts
- Set up client onboarding — ideally through a CRM that integrates with MT4 for seamless account creation
- Go live and begin client acquisition campaigns
Who Should Choose MT4 vs MT5 Grey Label?
Both options have their strengths. The choice comes down to your target market and client profile:
- Choose MT4 Grey Label if your clients are primarily retail spot forex traders, if your target market has high MT4 familiarity, or if you want the largest possible EA-compatible client base
- Choose MT5 Grey Label if you intend to offer multi-asset trading (stocks, futures, bonds alongside forex), if your target market includes more sophisticated traders familiar with MT5, or if you want access to MT5's more advanced order management features
There is no wrong answer — both models work. Many brokers launch with MT4 grey label and add MT5 later as their product offering expands. Starting with MT4 and the lower cost structure keeps your initial capital requirements to a minimum while maximising your market reach.
