Prop firm operator glossary
47 terms, defined in plain English.
Prop firm operator terms — the short answer
Most of the vocabulary of running a prop firm comes down to four questions: who takes the other side of a trade (A-book, B-book or hybrid), what enforces the rules (the risk engine), how money comes in and goes out (payment processor, payout rail, chargebacks), and whose technology it all runs on (white label, SaaS or self-hosted). The terms below are variations on one of those.
The prop firm business model
9 terms.
Affiliate programme
Paying partners a commission for challenge sales they refer, tracked by link or code.
Challenge fee
What a trader pays to attempt an evaluation. For an evaluation-model prop firm it is the main revenue line.
Disclosure grade
Prop Tech Pal’s A–E measure of how much of the diligence surface a technology vendor publishes — price, contract terms, security certifications, uptime and more.
Evaluation model
A prop firm business model in which traders pay a fee to attempt an evaluation, and those who pass trade a funded account for a share of the profits.
Introducing broker
A partner who refers clients to a broker or prop firm and is paid per client or on their activity.
Payout
A payment of profit share to a funded trader.
Profit split
The share of a funded trader’s profits paid to the trader, with the rest kept by the firm.
Revenue share
A pricing model in which a technology vendor takes a percentage of the prop firm’s sales instead of, or on top of, a fixed fee.
Simulated funded account
A funded account whose trades are not sent to a real market. The trader’s profit share is paid by the firm from its own revenue.
Technology and deployment
12 terms.
Back office
The operations side of a prop firm: payouts, KYC checks, invoicing, affiliate commissions, certificates and reporting.
Open API
A documented interface that lets the firm’s own systems read and change data in the vendor’s product.
Prop firm CRM
The system that runs the trader side of a prop firm: sign-ups, challenge purchases, the trader dashboard, emails and support.
Risk engine
The system that checks every account against the firm’s rules — drawdown, daily loss, consistency, prohibited strategies — and flags or acts on a breach.
SaaS
Software the vendor hosts and runs, which the firm uses through a subscription.
Self-hosted
Software licensed to run on the firm’s own servers or cloud account rather than the vendor’s.
Server licence
Running your own instance of a trading platform’s server, rather than a white label that shares the vendor’s.
Server plugin
Software installed on a trading platform’s server to add behaviour it does not have — most often risk rules for prop accounts.
Trader dashboard
The branded web area where a trader buys challenges, follows their rules and progress, and requests payouts.
Trading platform
The software traders place orders in — MT5, cTrader, Match-Trader, DXtrade, TradeLocker or a vendor’s own.
Turnkey solution
A package that bundles everything needed to open — platform, risk engine, CRM, payments and KYC integrations, sometimes the website — ready to switch on.
White label
Running a prop firm on another company’s platform, risk engine and CRM under your own brand.
Risk and rules
8 terms.
Breach
An account crossing one of the firm’s rules, which ends or suspends it.
Consistency rule
A rule limiting how much of an account’s total profit may come from a single day or trade.
Daily loss limit
The most an account may lose within one trading day, measured from that day’s starting balance or equity.
Drawdown
The loss limit on an account, measured from a reference balance. Breaching it ends the evaluation or the funded account.
Exposure monitoring
Watching the firm’s aggregate open positions across all accounts, by instrument and direction.
News trading restriction
A rule barring trades opened or closed within a window around scheduled economic releases.
Prohibited strategies
Trading behaviour a firm’s rules forbid — commonly latency arbitrage, tick scalping, hedging across accounts and copying other traders.
Trailing drawdown
A drawdown limit whose floor rises as the account makes new highs, so profit already made can count against the trader.
Execution and liquidity
11 terms.
A-book
Routing a trader’s orders to an external liquidity provider, so the market — not the firm — is the counterparty.
B-book
Keeping a trader’s orders in-house, with the firm as the counterparty. In the evaluation model this is the simulated account.
Bridge
Software that connects a trading platform’s server to one or more liquidity providers and passes orders and prices between them.
Hybrid model
Keeping most flow in-house (B-book) and routing selected traders or trades to the market (A-book), chosen by rules.
Latency arbitrage
Trading against prices that lag the real market — a slow feed — to capture a move that has already happened elsewhere.
Liquidity aggregation
Combining prices from several liquidity providers into one order book and routing each order to the best available quote.
Liquidity provider
The institution that quotes prices and takes the other side of orders routed to the market.
Price feed
The stream of prices a trading platform shows and fills against. Even a simulated account needs one.
Prime of prime
A firm that holds prime brokerage relationships with large banks and resells that access to smaller brokers and prop firms that could not get it directly.
Slippage
The difference between the price a trader asked for and the price the order filled at.
Toxic flow
Order flow that profits consistently from an information or speed advantage over the counterparty rather than from market views.
Payments and compliance
7 terms.
AML
Checks that stop a business being used to move illicit money — sanctions and watch-list screening, source-of-funds questions, transaction monitoring.
Chargeback
A card payment reversed by the cardholder’s bank after a dispute, with the money and a fee taken back from the merchant.
High-risk merchant account
A card-processing account for businesses a processor classes as higher risk, with higher fees, rolling reserves and closer monitoring.
KYC
Checking that a trader is who they say they are, usually with an ID document and a selfie, through a specialist provider.
Payment processor
The company that takes a trader’s card or crypto payment for a challenge and settles it to the firm.
Payout rail
The method used to pay traders and affiliates — bank transfer, crypto, or a payout platform.
Restricted jurisdictions
The countries a firm will not sell to or pay out to, because of sanctions, regulation or its own payment providers’ rules.

FAQs — Prop Firm Technology Questions Answered
Answers on tech providers, platforms, integrations and how our comparisons work
What is PropTechPal?
PropTechPal is an independent comparison platform built specifically for prop firm owners and operators who are evaluating technology providers. We provide structured, transparent comparisons of prop firm tech solutions - covering platforms, CRMs, risk management tools, challenge engines, and full-stack white-label providers - so you can make informed infrastructure decisions without relying on marketing material. PropTechPal is powered by Prop Firm Pal, the leading prop firm comparison site for traders.
How much does it cost to start a prop firm?
The cost to start a prop firm varies significantly depending on the tech provider and pricing model you choose. Some providers charge a one-time setup fee (ranging from $3,000 to $15,000+), while others use monthly subscriptions (typically $500 to $5,000+ per month depending on scale). Some operate on a revenue-share model where you pay a percentage of your gross or net revenue instead of fixed fees. Additional costs may include trading platform licensing (especially for MetaTrader), liquidity provider fees, payment processing fees, legal setup, branding, and marketing. PropTechPal helps you compare these costs across providers so you can find the right fit for your budget.
How long does it take to launch a prop firm with a tech provider?
Launch timelines vary by provider and the complexity of your setup. Most full-stack white-label providers can get a basic prop firm operational within 2 to 6 weeks. This includes platform setup, branding, payment integration, and challenge configuration. More customised setups with bespoke features, custom trading rules, or multiple platform integrations may take 6 to 12 weeks. Some turnkey providers advertise launches in as little as one to two weeks for standard configurations.
Can I use my own broker or liquidity provider with a prop firm tech platform?
In most cases, yes. Many prop firm tech providers are broker-agnostic and allow you to connect your own liquidity provider or broker. However, some full-stack providers bundle liquidity as part of their offering, and a few require you to use their integrated broker partnerships. If using a specific broker or liquidity provider is important to your business model, verify compatibility with the tech provider before signing up. PropTechPal lists integration capabilities for each provider to help you assess this.
How do prop firm tech providers detect cheating and fraud?
Modern prop firm tech providers use sophisticated detection systems including IP monitoring to identify linked accounts, trade pattern analysis to detect copy trading rings and hedging arbitrage, latency monitoring to catch exploit-based strategies, statistical analysis to flag abnormal win rates or risk-free profit patterns, device fingerprinting, and margin usage alerts. Advanced providers offer custom rule engines where you can define your own criteria for flagging suspicious activity. The quality of fraud detection is one of the most important differentiators between tech providers, as undetected abuse directly impacts your firm's profitability.
