Integral: FX and digital-asset technology, MTF and PrimeOne

Integral provides software and operating workflows for banks, institutional and retail brokerage businesses, payments firms, precious-metals businesses and crypto institutions. Its core role is to connect liquidity, price it, distribute it and manage the resulting execution and risk workflow. The current portfolio also includes two distinct financial-market services: Integral MTF and PrimeOne. These need to be understood separately from the underlying SaaS subscription, because they introduce different operators, access rules, fees and settlement arrangements.[1][22]

The FX price engine can vary pricing by customer, transaction size, tenor, product and execution style, including multi-leg and synthetic structures. That is different from simply displaying an aggregated best bid and offer. It lets a bank or broker define how upstream liquidity becomes a downstream customer price, while keeping the commercial configuration within the institution’s own workflow.[6]

Risk-management modules cover internalising flow, warehousing exposure and event-driven hedging, with analysis by dimensions such as currency, channel, customer segment and value date. They also describe trade pre-qualification and integration with external credit systems. These are configurable controls; they do not supply additional credit merely because a counterparty is technically connected.[9]

The public developer cookbook gives concrete evidence of API provisioning. A client receives a user ID, password, organisation ID and login URL, then obtains an expiring SSO token and includes it in subsequent requests. That is an authenticated, organisation-scoped integration, not an anonymous public market-data endpoint. Entitlements and credential lifecycle therefore belong in the deployment specification.[11]

Trade export is stateful. The documented STP endpoint returns executed trades not previously downloaded; the client polls until the response is empty. Previously downloaded trades require a separate prepare-to-resend action. A reconciliation process must therefore distinguish a normal incremental download from a recovery replay. An empty batch establishes that no further new trades are available for that poll, not that the organisation has no historical trades.[12]

Integral FX and Integral Digital advertise fixed-subscription technology models rather than a technology fee increasing with every transaction. Neither reviewed product page supplies a universal subscription amount, setup charge or minimum contract term. Execution-counterparty, credit and venue costs remain separate commercial questions. In particular, the published MTF schedule below belongs to the venue and should not be substituted for a SaaS quotation.[2][3]

The MTF schedule’s intra-customer exception concerns a buy-side entity receiving a price solely from one liquidity provider within the same controlled group. Its FX-strategy charges apply to each leg, so a two-leg transaction is not charged merely once against one displayed strategy amount. The fixed-subscription exemptions are material to an actual cost comparison.[16]

PrimeOne’s homepage advertises 1 basis point in its fee comparison. Arithmetically, that is $100 per $1 million of notional. The page does not define all inclusions or charging events, so the conversion is not an all-in tariff.[26]

Its FAQ says USD-per-million fees are provided during onboarding. The resulting quotation determines the account’s commercial terms; the public marketing figure alone does not define every charge.[27]

Integral FX supports separate regions, business lines and entities within one configured platform instance, and can be bought as a full stack or as selected modules. Its distribution layer exposes customer workflows through APIs, white labels and connected third-party venues. The implementation choice is therefore not just a front-end rebrand: it includes which pricing, routing, risk and reporting functions the institution wants Integral to operate.[2][7]

Integral Digital advertises deployment in 90 days or less. That is a vendor delivery claim, not a guaranteed timetable for every regulatory, counterparty or custody dependency. The product describes a central order book combining provider liquidity and customer orders, synthetic crosses and management of crypto/fiat exposure. Existing bilateral relationships remain relevant unless an alternative credit arrangement, such as PrimeOne, is separately established.[3]

For MetaTrader brokers, Integral describes automatic detection of symbol, security and account settings. Monitoring includes CPU/memory use, latency and symbol-data interruptions; configurable controls cover spreads, depth and order lifetime. The page’s lightweight-deployment language does not remove the actual MT4 plugin or MT5 executable described in its implementation instructions.[10]

MTF participation requires organisational onboarding, adequate financial resources and credit, and the ability to settle transactions. Applicants must be professional clients or eligible counterparties and cannot be natural persons. Technical connection alone therefore does not create venue membership or a settlement relationship.[15]

Integral publishes contact routes in several financial centres and an openly readable developer cookbook. The reviewed pages do not establish a universal contractual response time, incident-credit schedule or support-hours commitment for all products. A regional telephone number is an enquiry route; it does not, on its own, demonstrate continuous staffed incident coverage.[24]

Integral describes active-active infrastructure and sites in NY4, LD4, SG1 and TY3, and publishes a SOC 2 Type II claim. These statements describe its architecture and assurance position; the underlying assurance report and a universal uptime SLA were not inspected. The MTF contract specification separately states trading hours from Sunday 19:00 GMT to Friday 21:00 GMT. Venue hours, software availability and support response times are different measures.[1][17]

Integral MTF’s rulebook says that neither Integral nor an affiliate is a party to transactions on that venue. Participants trade with each other and must have the required settlement arrangements. The UK venue operator should not therefore be described as the prime broker or balance-sheet counterparty for every trade passing through Integral technology.[15]

The MTF operator published its year-end 2025 prudential disclosure on 23 April 2026. The reviewed disclosure addresses remuneration under the UK investment-firm framework; it is not a basis for inventing a standalone capital ratio. The Companies House entry independently confirms an active UK company, incorporated on 3 June 1996, while company registration remains distinct from regulated activity.[18][21]

Harpal Sandhu founded Integral in 1993 on the Stanford campus and is identified as its current chief executive. The company’s roots and headquarters are in Palo Alto, with current contact locations across North America, Europe and Asia. Its long-running institutional technology business now sits alongside the separately documented MTF and PrimeOne services; their presence should not turn the whole portfolio into one undifferentiated brokerage entity.[22][24]

Vistara Growth’s current portfolio page places Integral in its exited category. That is an important qualification to older financing announcements: the reviewed current source does not support presenting Vistara as a continuing owner. A complete current shareholder breakdown, transaction terms for that exit and consolidated public financial statements were not established from the reviewed official material.[23]

On the MTF, RFQ trading has an acceptance step. The July 2025 rulebook describes principal-to-principal transactions and permits a liquidity provider’s last-look accept/reject process, subject to its rules. A displayed response should therefore not be described as an unconditional execution. The contract specification identifies venue MIC IMTF and supports trade-specific instrument identification and maturities. These details are useful for reconciling venue activity with a participant’s own books.[15][17]

PrimeOne uses a different credit and settlement model. Its FAQ describes actual stablecoin variation-margin movements every minute, followed by daily net physical settlement at 17:00 New York time. It supports a third-party custodian or self-custody workflow. Those mechanics should be distinguished from a software P&L display: a treasury operation must handle collateral movements and final delivery, including the time zone and settlement cut-off.[27]

PrimeOne describes rules-based margining with trading capacity linked to posted collateral, and offers custody choices. Its marketing presents this as eliminating or greatly reducing counterparty credit exposure; that is not evidence that operational, legal, custody, stablecoin and settlement risks disappear. Its homepage also says new customers are introduced in stages through a waitlist. The rapid-onboarding claims elsewhere on the site therefore should not be interpreted as immediate universal availability.[28][26]

Integral Digital’s settlement module connects venues and counterparties to a custody account, aggregates executed trades, applies configured netting rules and produces settlement reports and audit records. PrimeOne separately describes a consolidated net-settlement API with notifications into existing operations and custodian systems. Both address post-trade work, but a customer must identify which service owns the workflow: software-led bilateral settlement and the PrimeOne credit arrangement are not interchangeable contractual structures.[13][29]

Integral’s FX Global Code disclaimer says it supports commitment to the Code but does not require every user to make that commitment. Platform membership is therefore not proof that all connected liquidity providers or customers are Code signatories. This is particularly relevant when an institution wants its execution or counterparty policies reflected in the liquidity pools it enables.[25]

The analytics tools can expose fill/reject behaviour, provider and customer flow, and system-health exceptions through dashboards, alerts and exports. Used alongside the STP download process, that provides two complementary views: what the system executed, and how the surrounding liquidity or workflow behaved. Neither a reporting module nor a completed download independently establishes best execution or guarantees an execution outcome.[8][12]
