FXCubic is a bridge to a venue’s contracted liquidity services. The current TRDRS-maintained integration implements FXCubic FIX API v1.2.2 and exposes the TRDRS public provider contract. Its test pricing only candidate is available as an owning-organization sandbox preview. Public listing review is pending; other organizations cannot install that preview.

​
What is available

The current release supports authenticated readiness, its manifest, and live bid/ask market data through a dedicated provisioned connection. The journal preserves quote sequence numbers across service restarts. It does not claim account discovery, order execution, execution history, account provisioning or production qualification. Listing does not enable those capabilities.

​
Connect your venue

  1. Once its public listing is approved, open Providers → Browse providers in sandbox Back Office and select FXCubic. Its maintainer can already see the sandbox preview. Read its release, contact and requirements.
  2. Contact TRDRS to arrange a dedicated deployment with your vendor-provided host, quote/trade credentials, account and connection requirements. The current service accepts one provisioned connection. A public listing does not share another venue’s private session.
  3. Add the pinned release to your venue, then create your private Connection with the endpoint and credentials supplied for that deployment.
  4. Run manifest validation. Successful manifest validation proves the declared contract; it does not grant trading permission. Market-data validation and order conformance are different checks.
FXCubic/vendor commercial access and liquidity arrangements remain yours to obtain. Before order execution is enabled, an authorized operator must complete the vendor’s coordinated conformance on its dedicated test account. Mainnet execution remains disabled until that evidence is accepted. See provider publishing for ownership and maintenance handoff, and provider self-check for the separate data and execution suites.

Current verification

On September 30, 2026, the sandbox service passed authenticated readiness and the engine’s manifest-validation request. A bounded EURUSD quote stream produced live bid/ask prices; after a service restart, the journal continued its durable sequence from 4 to 5/6 under a new generation. The provider journal contained zero commands and executions. These were read-only recovery checks. They are not a claim that vendor order conformance or every live execution self-check ran. The data-only self-check rules are also tested in hermetic CI with a disposable provider fixture. A maintainer supplies its own test evidence for publication review. The submitted candidate continues to declare execution and account discovery false.
