MT4 vs MT5: The Complete Comparison for Brokers

MT4 vs MT5 is the choice between two MetaTrader platforms built by MetaQuotes. MetaTrader 4 (MT4) is an older, forex-focused trading platform designed around hedging accounts and the MQL4 programming language. MetaTrader 5 (MT5) is a newer multi-asset platform that adds an exchange-style execution model, both netting and hedging account modes, more order types and time-frames, a built-in economic calendar and Depth of Market, and the more capable MQL5 language. In short, MT4 is a specialised forex terminal, while MT5 is a broader multi-market platform — and for new brokers, MT5 is the platform MetaQuotes actively licenses and develops.

The core difference at a glance

MetaTrader 4 was released as a dedicated forex and CFD trading terminal. Its design assumptions — a single hedging account model, MQL4 scripting, and a fixed set of order and time-frame options — reflect that focus. MetaTrader 5 was built as a general-purpose, multi-asset platform intended to serve exchange-traded instruments alongside forex. That difference in intent explains almost every feature gap between the two: MT5 was engineered to handle centralised order books, position netting, and richer market data, whereas MT4 was optimised for the over-the-counter forex model it launched with.

For a brokerage, the decision is less about which platform traders "prefer" and more about which one your instruments, execution model, and long-term roadmap require. The sections below break the comparison down feature by feature.

Asset classes and markets

MT4 was designed for margin forex and CFD trading, and it handles those instruments well. MT5 extends the model to a wider range of asset classes, including exchange-traded products where a centralised order book and Level II data matter. If your brokerage plans to offer only spot forex and CFDs, MT4's instrument coverage is adequate; if you intend to add or route to exchange-listed products, MT5's architecture is the better structural fit.

Order and execution types

Both platforms support the standard pending orders — Buy Limit, Sell Limit, Buy Stop and Sell Stop. MT5 adds two more: Buy Stop Limit and Sell Stop Limit, which place a limit order once a stop level is reached. On execution, MT4 offers Market, Instant and Request models. MT5 keeps those and adds an Exchange execution model suited to instruments traded through a central order book. For a broker running an agency or exchange-routed model, that additional execution type is a meaningful capability rather than a cosmetic difference.

Time-frames and indicators

MT4 ships with nine standard chart time-frames. MT5 ships with 21, giving analysts finer granularity between the common M1, M5, H1, H4 and daily intervals — for example intermediate periods such as M2, M10, or H2. Both platforms include a core library of technical indicators and support custom indicators, but MT5's larger built-in set and improved charting reflect its later design. For traders who rely heavily on multi-time-frame analysis, this is one of the more visible day-to-day differences.

Hedging vs netting account modes

This is one of the most consequential distinctions for how positions behave. In hedging mode, a trader can open multiple independent positions in the same symbol at the same time, including simultaneous long and short positions. In netting mode, all trades in a single symbol are consolidated into one aggregated position — a new opposing order reduces or reverses the existing position rather than sitting alongside it.

MT4 supports hedging only. MT5 supports both hedging and netting, configurable at the account level. Netting is familiar to traders coming from equity and futures exchanges, while hedging is the model most retail forex traders expect. MT5's ability to offer either mode lets a broker serve both audiences from one server.

MQL4 vs MQL5 and Expert Advisors

Automated trading on MetaTrader runs on Expert Advisors (EAs), custom indicators and scripts written in the platform's native language. MT4 uses MQL4and MT5 uses MQL5. The two languages share a similar C-style syntax, but they are not interchangeable: an MQL4 program will not run on MT5 without being ported and recompiled. MQL5 is an object-oriented language with a more complete standard library and a multi-threaded, multi-currency strategy tester, which makes backtesting and optimisation faster and more flexible.

For brokers, the practical implication is that an existing library of MT4 EAs does not transfer automatically to MT5. This migration cost is one reason to weigh the platform decision carefully before launch rather than switching later.

Depth of Market and Level II

MT5 includes a native Depth of Market (DOM) window that displays Level II order-book data — the available buy and sell volumes at each price level. This suits exchange-traded instruments and brokers who want to surface liquidity depth to clients. MT4 has no built-in Depth of Market feature. If your offering depends on showing order-book depth or on execution against a visible book, MT5 is the platform that supports it out of the box.

Back-office and reporting

Beyond the trader terminal, the two platforms differ in their server-side administration and reporting. MT5's manager and administrator tooling provides more granular reporting, account grouping and configuration options than MT4, and its data model was built to feed modern integrations. When a broker connects a CRM and back-office layer over the top, richer native reporting reduces the amount of custom work required. You can see how the wider stack fits together on our trading platform overview, which covers how the terminal, CRM and reporting layers connect.

Which should a new broker choose?

For most new brokerages, MT5 is the more future-proof choice. It covers a wider range of asset classes, supports both account modes, includes Depth of Market and a stronger strategy tester, and offers more complete back-office reporting. Critically, MetaQuotes has focused its new server licensing on MT5, so launching on MT5 keeps a broker aligned with the platform that receives active development and avoids a costly migration down the line.

There is one important commercial reality to understand. MetaQuotes licenses its server software directly and vets applicants, and it has concentrated new licensing around MT5. In practice this means most brokers do not buy a standalone full license off the shelf; instead they access the platform through an authorised main-label or white-label provider. That licensing context is exactly what pushes new entrants toward the white-label and main-label routes rather than a direct, from-scratch license. Our forex white-label solution explains how that path works and what it includes.

How FxTrusts delivers branded MT5

FxTrusts delivers MetaTrader 5 as a fully branded platform so a broker can launch under its own identity without navigating the licensing and infrastructure alone. That includes your logo and branding on the terminals, server setup and instrument configuration, hedging or netting account modes as your model requires, and integration with CRM and back-office reporting. Because MT5 is the platform MetaQuotes actively supports, building on it keeps your brokerage current rather than tied to a legacy terminal.
