Reference buildPart of the Finxis CDM toolchain

A trading application, generated from the model.

CDM Trader renders a trade ticket from a product specification — the business fields a trader actually books, mapped onto the CDM paths behind them. Fill it in, and the object you end up with is valid CDM all the way down. Add a specification to the library and the product appears here.

Trade ticket — IRS fixed-float, generated from irs-fixedfloat CDM 7.0.0

CDM Trader trade ticket for a fixed-float interest rate swap, showing one column per leg with schedule and rate fields, and badges marking which values came from the canonical template

The ticket

A form that knows what it is looking at.

A generated UI can easily become a flat list of every field in the model, which is complete and unusable. Trader works from a product specification instead: the business fields a trader books, each mapped to its CDM path, with the rest derived or seeded from the canonical product.

PROVENANCE

Every field is tagged

Set, derived, or required and empty. You can see at a glance what you entered, what the model worked out, and what is still missing.

TRACEABILITY

CDM paths on screen

Each leg carries its path — payout[0] · interestRate — so the form is visibly the model rather than something sitting beside it.

DERIVED

The model does the arithmetic

Contra amount from base and rate, receiver from payer. Derived values are computed and marked, not typed.

Generated, not built

The library is the application.

Most multi-asset applications are a screen per instrument, hand-built and hand-maintained. Trader has none. It renders whatever specification it is given, so coverage grows by writing a specification rather than by writing a screen.

Pick a product

Any product in the library with a specification, at the CDM version you are running.

Ticket renders

Business fields laid out from the specification, seeded from the canonical product.

Book it

Values validate against the model as you enter them, not after you submit.

Run the lifecycle

Allocation, novation, termination and the rest, executed as CDM events.

That is also why Trader is the honest answer to "should we build this ourselves?" — it is the thing a team would spend a year building, and the parts that took the year are the ones you would rather not maintain.

Architecture

A front end over CDM Node.

Trader does not reimplement the CDM. The interface renders and edits the object; validation, qualification and lifecycle execution happen in CDM Node, against the generated Java. One implementation of correct, not two.

Layer	Does	Runs
Trader front end	Renders the ticket, builds and edits the CDM object	Browser
Product specification	Business fields, their CDM paths, and what is derived	Versioned with the library
Canonical library	Seeds the object the ticket populates	Versioned with the CDM release
CDM Node	Validation, qualification, lifecycle events, persistence	Your infrastructure

Which means a firm evaluating Trader is evaluating Node at the same time — and a firm that already runs Node has most of what Trader needs.

Coverage

What you can book.

A product is bookable once it has a specification. The library is ahead of the specifications in some asset classes — those products are browsable today and bookable as their specifications are written.

Asset class	Examples	Bookable	In library
Interest Rate	Fixed/float, basis, OIS, cross-currency, swaptions, caps and floors, FRAs	15 live	15
Foreign Exchange	Spot, forwards, swaps, NDFs, vanilla and non-deliverable options	7 live	7
Equity	Listed equity, price and total return swaps, CFDs	1 live	23
Credit	Single name, index, tranche, swaptions	Planned	44
Debt	Bonds	Planned	—
Commodity	—	Planned	—
Financing	Repo, securities lending	Planned	—

Every product in the library is browsable before you book anything — structure and canonical JSON, in the product library. Specifications are being written class by class; tell us which you need and we will prioritise it.
