IDBX previews mobile market monitoring while keeping orders on the dealing desk

IDBX has previewed a mobile interface for its planned interbank venue, extending market and position monitoring beyond the dealing desk while reserving order entry for the desk. Its 18 October announcement describes an App Store release as forthcoming and offers a browser preview for prospective participants.[1][2]

The operational status is explicit in the firm’s developer documentation: IDBX Markets Ltd is not currently authorised by the Financial Conduct Authority. The interface can be exercised in a sandbox, with production access dependent on authorisation and institutional onboarding. The published technical design is therefore a basis for evaluation before a regulated service begins.[3]

IDBX says the phone and desktop will use the same feed, displaying prices, matches, positions and netting information, with settlement dates attached to fills. The phone is view-only. Keeping order entry within the dealing environment preserves the place where the company says recording requirements and execution controls apply, while allowing staff to inspect the market away from their terminals.[2]

The AI component has a separate boundary. IDBX describes AIDANN as an analytical assistant that cannot place, change or cancel orders, or alter settlement instructions. Its published browser examples use illustrative books and reproducible calculations. The firm says those examples assemble answers from fixed templates rather than a language model; they demonstrate proposed functions without establishing live-market performance.[4]

The broader Nexus platform, unveiled on 16 October, is intended to cover rates, FX, bonds, money markets and tokenised assets under a subscription model. That supplies the business context for the mobile interface: IDBX wants institutions to pay for access rather than each trading ticket.[1]

Its cost calculator is an illustration, however. Users enter their own trading activity and brokerage rates, and the assumed platform fee is also their estimate. The calculator contains neither a live tariff feed nor named competitors’ charges. Whether a subscription saves money consequently depends on the actual agreed fee and the desk’s activity; the published tool does not establish a universal saving.[5]
