Glossary · 44 terms

Broker and fintech technology, defined in plain words.

The words that come up when a broker, prop firm or payment business buys software: what each one means, in under 60 words, and where EntropyX Labs supplies it or leaves it with you. Every term links to the product or guide that goes deeper.

Last updated 2026-11-13

A-book and B-book

A

Two ways a broker handles client orders. A-book passes them to a liquidity provider and earns the spread or commission; B-book keeps them on the broker's own book and carries the market risk. Many brokers run both, by client or instrument. EntropyX Labs does not route or hold orders; EA Panel shows the exposure so the desk decides.

Address screening

A

A check of a blockchain address against sanctions lists and risk indicators before a deposit is credited or a payout is sent. EntropyX PSP exposes hooks for a screening provider; Crypto Tools traces funds after the fact. The policy and the choice of provider stay with the operator.

AI trading assistant (co-pilot)

A

Software that answers a trader's questions with data, forecasts and rankings while the human keeps every decision. SignalDesk is one: it answers across 1,000+ symbols with a conviction score and a visible tool trace, and does not place trades. Whether such a tool is investment advice depends on how it is offered; the guide draws the line.

Audit log

A

An append-only record of who did what and when: logins, approvals, interventions, KYC decisions, payouts and configuration changes. Regulators and disputes both ask for it. EntropyX Labs products write one per action and let you export it; the security page describes the controls around it.

BEP20, TRC20 and ERC20

B

Token standards on BNB Smart Chain, Tron and Ethereum. USDT exists on all three, with different fees and confirmation times, and a transfer sent on the wrong network does not arrive. EntropyX PSP allocates a deposit address per client and per network on each of the three.

Bridge (liquidity bridge)

B

Software between a trading platform and liquidity providers that routes orders, aggregates prices and applies mark-ups and risk rules. Vendors such as oneZero, PrimeXM and Centroid supply bridges (names from vendor pages read 5 November 2026). EntropyX Labs does not; the bridge stays with your platform set-up.

Brokerage CRM (forex CRM)

B

The client-account system of a broker: onboarding and KYC, the traders' room, accounts and funding, the sales pipeline, support context and compliance records in one place. Brokerage CRM is the EntropyX Labs product; the guide explains what a forex CRM is and what it costs.

Challenge engine (prop firm)

C

The software that runs a prop firm's evaluation: phases, profit targets, drawdown rules, pass and fail logic and payout schedules, enforced per account. EntropyX Labs builds one on request on the same identity layer as Brokerage CRM and EA Panel; the rules, who passes and the capital stay with the firm.

Compliance calendar

C

A schedule of statutory filings and deadlines per client, with owners, reminders and status, used by accounting and company-secretarial practices. CA_CS Tool keeps one for Indian CA and CS firms; the guide covers practice management software for them.

Conviction score

C

A number SignalDesk attaches to an answer to say how strongly the evidence it gathered supports that answer, computed from the tools it ran. It measures agreement across the evidence, not the probability of a profit, and it never places a trade.

Copy trading

C

Mirroring a leader's trades into each follower's own account, which stays under the follower's control, usually with per-follower scaling, caps and instrument whitelists. Social Copy does this across MT5 servers. It differs from PAMM and MAM, where funds or allocations are pooled into managed accounts.

Cross-server copy trading

C

Copy trading where leaders and followers sit on different MT5 servers or brokers, so the engine mirrors trades through the platform APIs rather than inside one server. Social Copy is built for this, and its execution respects slippage and liquidity instead of blindly mirroring.

cTrader

C

Spotware's trading platform for FX and CFD brokers, sold as platform-as-a-service hosted by Spotware, with cBots, cTrader Copy and a white-label route through existing cTrader brokers (vendor pages read 6 November 2026). EntropyX Labs does not license or host it; whether a product connects to it is scoped per engagement.

Dealing desk

D

The team that manages a broker's market risk: exposure, pricing adjustments, interventions on accounts and hedging. EA Panel is the operations console for it, with exposure dashboards, intervention workflows with approvals, role-based access and an audit log. The decisions remain the desk's.

Double-entry ledger

D

Bookkeeping where every movement is recorded twice, as a debit and a credit, so balances always reconcile. EntropyX PSP posts every confirmed deposit and settlement to one, which is what makes its reconciliation exports auditable line by line.

DXtrade

D

Devexperts' trading platform for brokers, delivered as SaaS the vendor hosts and maintains, in a CFD edition for FX, CFDs, spread bets and crypto and an XT edition for listed markets (vendor pages read 6 November 2026). EntropyX Labs does not license or host it; whether a product connects to it is scoped per engagement.

Entropy (in markets)

E

A measure from information theory of how unpredictable a sequence is. Applied to prices and order flow, it indicates how much structure a market has at a given moment. Papers co-authored by our founder use it to find quality patterns, signatures of extreme events and market responses to policy news; SignalDesk builds on the first two.

Exposure

E

A desk's net open position per instrument, client group or book, and therefore its sensitivity to a price move. EA Panel shows exposure in real time and carries caps that the engine enforces; the limits themselves are set by the firm.

IB rebate (lot-based, revenue share, CPA)

I

What a broker pays a partner for the clients it refers: a fixed amount per lot traded, a share of the spread or commission, a one-off sum per funded client (CPA), or a mix. The schedule sits in the partner agreement. Brokerage CRM tracks rebate rules and payouts per partner; the terms are yours to set.

Introducing broker (IB)

I

A partner who refers clients to a broker and earns a share of their spread or commission, often in tiers. An IB programme tracks referrals, rebates and payouts. Brokerage CRM tracks IBs and affiliates with tiers and rebates on the same client record; the forex CRM guide covers what to expect.

KYC and KYT

K

Know Your Customer verifies who a client is before onboarding; Know Your Transaction screens the movements afterwards, including blockchain transfers. Brokerage CRM carries the KYC document pipeline with reviewer queues; EntropyX PSP and Crypto Tools cover the transaction side. The policies are the operator's.

Liquidity provider

L

A bank, non-bank market maker or prime-of-prime that quotes the prices a broker trades against. Choosing and contracting one is the broker's decision; EntropyX Labs does not provide liquidity or route to it. The provider guide lists the kinds of vendor that do.

Live translation

L

Real-time translation of messages or speech inside a chat, so a multilingual desk can read one channel in each member's language. EntropyX Chat does this inside a self-hosted deployment, alongside its audit logs and admin-only onboarding.

Master IB and sub-IB

M

A master IB is an introducing broker who recruits other IBs (sub-IBs) and earns an override on the clients they refer, on top of its own referrals. The broker's partner system must hold that hierarchy and split each rebate across its levels. Brokerage CRM tracks IBs and affiliates with tiers and rebates on the client record.

MetaTrader 5 (MT5) and the manager API

M

MetaQuotes' retail trading platform and the server-side interface a broker's software uses to create accounts, move balances, change groups and read trades. Brokerage CRM, EA Panel, Social Copy and FX Auto-Pilot connect to MT5 this way. EntropyX Labs does not license or host MT5 servers.

Netting and hedging accounts

N

Two ways a platform books positions in one symbol: netting keeps one net position per instrument; hedging keeps each order as its own position, long and short at once. MetaTrader 5 runs netting for exchange instruments and hedging for forex (MetaQuotes page read 6 November 2026). The broker sets it per platform group; EntropyX Labs does not.

PAMM and MAM

P

Percentage Allocation Management Module pools investor funds into one managed account and allocates results by share; Multi-Account Manager keeps separate accounts and allocates trades by a rule. Both differ from copy trading, where followers keep their own accounts. EntropyX Labs supplies copy trading as a product (Social Copy) and builds PAMM or MAM on request.

Payment orchestration (stablecoin)

P

Software between a business and the chains it accepts stablecoins on: address allocation, routing, conversion, screening, reconciliation and webhooks through one API. EntropyX PSP covers stablecoin deposits and withdrawals without conversion or custody; the guide compares how four vendors define the category.

Platform licence vs white label

P

With a licence the broker runs the trading server itself and owns the set-up; with a white label it rents a branded instance on another firm's server and depends on it for hosting and maintenance. MetaQuotes sells MT5 licences in tiers; MT5 white labels come from licence holders and cTrader white labels from cTrader brokers. EntropyX Labs sells neither.

Postback (server-to-server tracking)

P

A server-to-server call one system makes to another about an event. In affiliate and IB tracking, the broker's CRM tells the affiliate platform a referred trader registered, deposited or traded, so the partner is credited without browser cookies. Brokerage CRM keeps partners on the client record, so its own IB module needs none; external platforms are connected per engagement.

Profit split (prop firm)

P

The percentage of a funded account's profit that a prop firm pays to the trader, as its terms set out. Software calculates it for each payout window after checking the account's rule events. EntropyX Labs builds profit-split and payout logic on request on the Brokerage CRM trader record; the split itself is the firm's decision.

Prop trading firm (evaluation model)

P

A firm that lets traders qualify through a paid evaluation with drawdown and target rules, then trades firm capital on their behalf and shares the profit. The rules, capital and payouts are the firm's; the technology checklist guide lists what the firm needs to run them.

Reconciliation

R

Matching every transfer a system saw to the account and ledger entry it belongs to, and reporting what did not match. EntropyX PSP reconciles USDT deposits automatically and exports the result, so finance can audit it line by line.

Self-hosted (on-prem, VPC)

S

Software that runs on servers the operator controls, in its own data centre or cloud account, with its own keys and database, instead of on the vendor's. Every EntropyX Labs product can run this way; EntropyX Chat and EntropyX PSP are self-hosted by design.

Signed webhook

S

An HTTP notification one system sends to another when something happens, carrying a signature the receiver can verify, so a forged or replayed call is rejected. EntropyX PSP notifies the CRM this way when a deposit confirms.

SLA (service level agreement)

S

A commitment on response and resolution times, often per priority, with reporting against it. EntropyX Tickets tracks SLAs per queue and shows CRM context on every ticket; the service levels promised to clients stay the operator's.

Stablecoin (USDT)

S

A token designed to hold a fixed value against a currency, usually the US dollar. Tether's USDT is the one brokers' clients most often deposit, on TRC20, BEP20 and ERC20. The guide explains how brokers accept it and what to reconcile.

Technology provider (versus white label)

T

A vendor that supplies software around the platform and licences you hold yourself, so the platform, liquidity and regulatory status stay yours. A white label instead gives you a branded copy of another firm's stack. EntropyX Labs is a technology provider; the guide explains how to choose one.

Tool trace

T

The visible list of tools an AI assistant ran to produce an answer, with their inputs and outputs, so a reviewer can check the reasoning rather than trust the prose. SignalDesk shows one for every answer and logs it.

Traders' room (client portal, client cabinet)

T

The client-facing part of a broker's CRM, also called a client portal or client area: registration, KYC upload, account opening, deposits and withdrawals, documents and support requests. Brokerage CRM includes one on the same client record the back office uses, so sales, support and compliance see the same account.

Travel Rule

T

A requirement, from FATF Recommendation 16, that virtual-asset service providers share originator and beneficiary information with each other for transfers above a threshold. Whether it applies to you depends on your licence; the stablecoin orchestration guide notes which vendors offer it.

Two-factor authentication (2FA)

T

A second proof of identity at login, such as a one-time code, in addition to the password, so a stolen password alone does not open an account. Brokerage CRM includes it; the security page describes access control across the products.

Volatility regime

V

A classification of current market conditions by how much prices are moving relative to their own history, for example a percentile of recent volatility. SignalDesk reports it as one input to an answer; it does not predict the next regime.

White label

W

A branded copy of another firm's trading stack, often with its liquidity and sometimes under its licence, offered by platform vendors and large brokers. It is the fastest start and the deepest dependency. EntropyX Labs does not offer white labels; the provider guide weighs the choice.
