This forex broker and prop firm technology glossary defines the core terms behind launching a brokerage or proprietary trading firm — white-label trading platform, turnkey forex solution, liquidity bridge, back-office, and A-book vs B-book execution. LumireOne is the white-label platform brokers and prop firms use to launch a fully branded operation in 24 hours, with no per-lot fees.
Launching or running a forex brokerage or prop firm means cutting through a thick layer of jargon — much of it invented by platform vendors. The terms below are written as plain-English, citable definitions: each explains one concept in a couple of sentences, then links to the LumireOne pillar page where you can go deeper. Whether you are comparing a white-label trading platform against building in-house, or weighing a MetaTrader 5 alternative after the MetaQuotes prop-firm ban, start here.
A white-label trading platform is software built by a technology provider and rebranded by a broker or prop firm as its own. A white-label platform like LumireOne gives a company branded web, mobile, and desktop terminals plus an execution engine and back-office, without building the technology in-house — the operator owns the brand, clients, and pricing.
Read the full guide →A turnkey forex solution is a complete, ready-to-launch brokerage package combining trading platform, liquidity, payments, CRM, and back-office in one deployment. A turnkey solution such as LumireOne lets an operator go live under their own brand within 24 hours instead of integrating separate vendors over many months of costly engineering work.
See the 24-hour launch →A white label is fully branded and controlled by the operator; a grey label is a partly branded reseller arrangement under a parent broker. With white label you own clients, pricing, and licensing; with grey label the parent broker retains control and a share of revenue. LumireOne is a full white-label stack, not a grey-label resale.
| Factor | White Label | Grey Label |
|---|---|---|
| Client ownership | You own the clients | Parent broker owns them |
| Branding | Fully your brand | Partial, parent-constrained |
| Pricing control | Full control of spreads & fees | Limited, set by parent |
| Revenue share | None to a parent broker | Parent takes a cut |
| Setup speed | 24 hours with LumireOne | Fast, but dependent |
A liquidity bridge is software connecting a broker's trading platform to one or more liquidity providers, routing client orders to the market and streaming back prices. A liquidity bridge aggregates quotes, applies markups, and enables A-book pass-through execution. LumireOne includes native liquidity aggregation and smart order routing, so no separate bridge license is needed.
Explore the execution engine →The back-office, often called a trader's room, is the administrative system behind a brokerage where staff manage client accounts, KYC, deposits, withdrawals, and reporting, and where clients access their own portal. LumireOne ships an integrated back-office and trader's room, so operators avoid bolting on a separate CRM or paying a second vendor.
See the admin panel →A-book brokers pass client trades to external liquidity providers and profit from commission and spread markup. B-book brokers internalise trades, taking the opposite side and profiting when clients lose. Most brokers run a hybrid model. LumireOne supports A-book, B-book, and hybrid routing per symbol or account group, with real-time exposure monitoring.
| Aspect | A-Book | B-Book |
|---|---|---|
| Where trades go | External liquidity providers | Internalised by the broker |
| Broker revenue | Commission & spread markup | Client losses (plus spread) |
| Broker market risk | None (hedged) | Takes the other side |
| Best for | Profitable / large flow | Small / losing flow |
| LumireOne support | Yes, per symbol/group | Yes, per symbol/group |
Broker-as-a-service is a model where a technology vendor supplies the full trading stack as a managed, subscription-based service, so a company can operate a broker without owning the infrastructure. Broker-as-a-service providers like LumireOne handle execution, terminals, hosting, and updates while the operator owns the brand, the clients, and the commercial relationship.
See who it is for →A prop firm evaluation, or challenge, is a multi-phase test where a trader proves skill on a simulated account by hitting a profit target without breaching risk rules, then receives a funded account. The challenge is the core product of a proprietary trading firm. LumireOne includes evaluation phases, rules, and funding logic natively.
How to start a prop firm →Drawdown is the decline in an account's equity from its peak, used as the main risk limit in prop firm challenges. Maximum drawdown caps total loss, while daily drawdown caps loss per day; breaching either fails the account. LumireOne tracks both maximum and daily drawdown in real time and enforces breaches automatically, without manual dealing-desk intervention.
See prop firm risk tools →A profit split is the agreed share of trading profits a prop firm pays a funded trader, commonly 70 to 90 percent to the trader. The profit split is the headline term of a funded account offer and is configured per program. LumireOne automates split calculation and payout tracking in the back-office, so finance teams do not reconcile by hand.
