4OTC: FX and digital-asset connectivity, liquidity bridges and post-trade feeds

The current catalogue lists FX spot, forwards and NDFs for 1API and Libre. For digital assets, 1API supports spot, perpetuals and futures. TicketLounge adds FX swaps and NDF swaps to its post-trade coverage and includes both exchange and OTC digital-asset tickets. Product coverage should be read separately from venue coverage.[1]

Cobalt’s February 2021 deployment demonstrates the market-data use case: a downstream infrastructure business obtained FX and digital-asset feeds through 1API. The benefit described is simpler data management and faster addition of venues. Cobalt’s own credit, collateral and risk functions remain separate from the connectivity service supplied by 4OTC.[6]

Quod contributes algorithmic trading, smart order routing, liquidity internalisation and its risk controls to the joint proposition. These capabilities should not be relabelled as native 4OTC modules.[7]

The current product page offers FIX and SBE integration. Earlier 1API launch material also described Java and .NET client components. That historical client-library disclosure is useful implementation context, but it does not establish current language-version support or a publicly accessible SDK maintenance schedule.[1][3]

The pricing status is therefore not disclosed. The free-trial invitation is concrete evidence of trial availability; it does not establish that ongoing production access is free. Likewise, a connected venue or client logo does not establish whether its market-data entitlement, trading agreement or connection charges are included in a 4OTC subscription.[1][9]

4OTC’s current About page describes adding an FX connection within days and a digital-asset venue within two weeks. These are supplier statements about connectivity delivery. They do not establish the elapsed time for a new institution to complete its own venue agreements, internal approvals and full production migration.[2]

B2C2’s release is useful evidence of a staged rollout: several exchanges were already connected and more were being added. It illustrates why a documented live integration can coexist with continuing coverage work. No complete current exchange-by-instrument certification matrix was available in the reviewed material.[9]

4OTC says it assists with integration to its API or client libraries and advises on cloud configuration. The public pages do not publish a client incident telephone number, severity-based response timetable or service-credit formula. Those details cannot be inferred from the continuous operation of the market-data network.[2]

The contact page reports more than 50 billion messages daily and continuous year-round operation. Those are company-published scale and availability descriptions. They do not provide an independently measured uptime percentage or promise a particular response time to an individual support request.[12]

The Companies House entry identifies 4OTC Limited, company number 12438405, as an active private company with a software-related business classification. This verifies the corporate identity. It does not by itself establish a financial-services permission, and the profile does not treat a connectivity supplier as a broker merely because its systems carry trade messages.[14]

4OTC Limited was incorporated in England on 3 February 2020. Its current registered office is 86–90 Paul Street, London. The 2021 founder announcement identifies Alexis Atkinson, Russell Fernandes and Mark Price as the team behind the business, with backgrounds in FX trading systems and performance engineering.[14][10]

In March 2025, 4OTC announced Kyle Jannece as head of business development. The release connected its expansion to traditional FX institutions adding digital assets and to the broader suite of trading and post-trade services.[11]

The published privacy route also allows escalation to the UK Information Commissioner’s Office if a concern remains unresolved. This concerns personal-data handling. The inspected notice does not supply a separate contractual process for a dropped order message, duplicate ticket or trading-loss dispute.[13]
