Web trading & edge hosting glossary

A multi-asset trading platform developed by MetaQuotes.

A trading terminal that runs in a web browser.

The MT5 WebTrader lets clients log in and trade without installing software, on desktop or mobile browsers.

A web terminal presented under a broker’s own brand and domain.

It shows the broker’s company details and legal links, on an address such as trade.yourbrand.com.

Access to MT5 through another company’s licence and server.

A white label gives a broker a branded slice of a provider’s MT5 installation. It differs from a white-label WebTrader, which concerns how the web terminal is delivered.

An MT5 licence held directly with MetaQuotes.

The broker operates its own MT5 servers and can create white labels for others.

MetaQuotes has restricted such arrangements since 2024.

The MT5 server that holds accounts and executes trades.

Clients choose or are connected to the broker’s trading server when they log in.

Serverless code that runs inside Cloudflare’s network.

Workers run in data centres in more than 300 cities, close to users, without servers to manage.

A network of data centres close to end users.

Serving content from the edge reduces distance and improves responsiveness for users worldwide.

A named setting stored outside the code.

In FXPTrader, branding, server and access settings are environment variables edited in the Cloudflare dashboard.

A server that sits in front of another service and forwards requests.

Traditional branded terminals used Nginx or OpenResty on a VPS as a reverse proxy.

Web trading terminals use WebSockets for live prices, charts and order updates.

The certificate that enables HTTPS.

Cloudflare issues and renews certificates automatically for domains it manages.

Defence against floods of malicious traffic.

Cloudflare’s network absorbs and filters attacks before they reach your service.

A range of MT5 account numbers allowed to use a terminal.

For example 5000-6000. Accounts outside allowed ranges are refused with the standard MT5 error.

Running several brands, each with its own terminal.

Each brand can have its own domain, branding, trading server and login ranges.

A firm that evaluates traders and funds successful ones.

A partner who refers clients to a broker in return for commission.

IBs often want a branded platform for their community; a partner-branded terminal limited to the IB’s account range provides it.

The MT5 server component that clients connect to.

MetaQuotes’ current web terminal runs on each broker’s access server.

An HTML element that shows one web page inside another.

Some brokers embed the MT5 web terminal in an iframe on their website; a dedicated subdomain gives more space and clearer branding.

Serving the terminal from locations near traders reduces delivery latency.

Cloudflare Workers are serverless: the platform runs your code on demand across its network.

Crypto CFDs trade around the clock, so web terminals must always be available.

A branded web terminal linked from the client area shortens the path to the first trade.
