LMAX Digital: institutional spot markets, fees, custody and membership

LMAX Digital serves institutional and qualifying professional clients through a central order book for physically delivered digital assets. The professional client account and direct exchange membership have different contractual and settlement arrangements. Admission to one route should not be read as approval for the other.[1]

The published session runs continuously apart from a daily 17:00–17:05 EST/EDT break. This is New York local time, so its UTC equivalent changes with daylight saving. Spot trading should not be conflated with the derivatives offered by other LMAX Group companies.[2]

Execution and connectivity

The execution policy describes LMAX as sole principal counterparty for its client route, normally placing an offsetting order into its own venue or another liquidity pool. It may use another pool when orderly execution cannot be maintained on the primary venue. Limit orders constrain price; market and stop orders can fill at different prices, including partial fills. A stop instruction does not guarantee the trigger price.[6]

Fees distinguish passive orders that add liquidity from aggressive orders that remove it. One basis point is 0.01% of executed notional. The following is the published monthly-volume schedule, rather than a spread estimate or a guarantee of the total execution cost.[2]

For ordinary participants, aggressive trades are initially charged at six basis points; monthly qualifying rebates apply retrospectively to the whole month’s volume. Passive and aggressive volume count together. The public inequality labels leave the exact USD100 million and USD200 million boundaries unstated. Confirm the boundary treatment and any market-maker obligations in the fee agreement.[7]

The new-client page specifies a minimum initial deposit of USD100,000 or the equivalent in crypto. Fiat arrives by bank transfer and crypto through the account’s supported settlement route. Obtain the account-specific instructions through the Client Portal; a general website listing is not a wallet address or authority to pay a third party.[3]

The terms provide fiat withdrawal processing by the second business day, subject to verification, set-off and holds. Crypto delivery may take three business days after processing. These contractual clocks differ from a completed bank credit or blockchain confirmation.[5]

Under the October 2023 terms, ordinary fiat can be held in unsegregated pooled accounts and mixed with LMAX’s own money. Ordinary crypto uses pooled cold wallets. Separately agreed custody should not be assumed to change the treatment of every trading-account balance.[5]

The custody factsheet shows a transaction moving from initiation through multiple signatures, including an offline signing stage, to broadcast and interface confirmation. The structure makes approval workflow and authorised signatories part of the withdrawal process. The asset schedule, signing authority and any segregation addendum belong in the institution’s custody mandate.[15]

This is an institutional and professional-client venue. The new-client form describes an elective professional test requiring two of three criteria: significant trading activity averaging ten transactions per quarter over four quarters; a financial-instrument and cash portfolio above USD600,000; or at least one year of relevant financial-sector professional experience. Passing a numerical screen does not itself constitute admission.[3]

Direct members must satisfy the rulebook’s professional-client, reputation, competence, governance and financial-resource requirements. Members may trade as principal or execute back-to-back for clients. The intermediary remains responsible for its own client relationships and the obligations it assumes on the venue. Country, sanctions and legal restrictions still require an account-level determination.[8]

A complaint should identify the account, disputed event, relevant correspondence and requested remedy. The published policy provides an acknowledgement by the close of the fifth business day if unresolved, and a written response within eight weeks. It does not establish a UK Financial Ombudsman entitlement for this Gibraltar account.[11]

The execution policy permits telephone dealing during Helpdesk Hours. Verify the dealing number and opening hours in the onboarding documents before treating this as an outage route. Client connectivity failure alone does not prove that a working order has been cancelled.[6]

The current GFSC record connects the named Gibraltar entity to secondary-market virtual-asset trading and custody. Those permissions should not be applied to other LMAX companies or treated as a worldwide derivatives authorisation. The register’s incorporation date is 18 June 2018.[13]

LMAX Digital is part of LMAX Group and presents itself as an institutional spot venue and custodian. Its client and member model makes consumer account counts a poor measure of its role: a participating broker or institution may serve many underlying clients without those individuals being direct LMAX Digital account holders.[1]

The September 2026 KPI page reports USD37 billion monthly notional, 8,176,130 trades and USD205 billion year-to-date. These are explicitly LMAX Group digital-asset aggregates combining LMAX Digital spot and derivatives at LMAX Global entities. They are not LMAX Digital spot-only volume. The publisher also notes the methodology change, so older series are not directly comparable. No current direct-client count was established.[14]

Member risk controls and order persistence

API access requires agreed due diligence, security procedures and conformance testing. The API agreement warns that orders submitted before a connection failure may remain active and execute. A technical disconnection is therefore different from an acknowledged cancellation. Recover order state and reconcile execution messages before resending; the agreement also anticipates throttled or batched events and possible sequence gaps.[9]

An institution must test its own software against the agreed interface and stop using a materially defective integration until the issue is resolved. The API contract permits suspension for security or market integrity. The agreement also limits support commitments and allows interface changes; operating an algorithm through the API does not make LMAX the algorithm’s investment manager.[9]

For market disruption, the rulebook permits suspension, cancellation or price adjustment under specified powers, including assistance where a member cannot remove orders. Members must retain transaction records for at least five years. These extraordinary interventions should not be treated as an unconditional right to reverse an executed trade.[8]

Records, account closure and a cost illustration

Electronic confirmations and statements cover trades and cash movements. The terms require disputed trade details to be raised within 24 hours. Six years without balance movements can start an unclaimed-assets process after unsuccessful tracing; this differs from a routine inactivity charge. Termination can require trade closure and immediate payment.[5]

On a hypothetical USD1 million filled order, two basis points equals USD200; six equals USD600. A four-basis-point final aggressive rate would be USD400, and three would be USD300. These are per-side commissions only. Spread, price movement, currency conversion and separate service charges are excluded.[3]
