What market data does my valuation require?

Your recipe must be able to locate market data suitable for each type of instrument you wish to value in an appropriate LUSID store.

The quality and quantity of market data required depends upon:

  • The instrument types being valued, for example Equity, Bond, FxForward, InterestRateSwap and so on.

  • The pricing models chosen, for example SimpleStatic, Discounting, BlackScholes and so on. Note not all pricing models are valid for each instrument type.

  • The number of days in the valuation schedule.

To help you discover what market data your recipe must locate for a particular combination of an instrument type and a pricing model valid for that type, call either:

Note: If you find you need an additional license to use these APIs, contact Technical Support.

Consider the following example of a call to the QueryInstrumentCapabilities API with the economic definition of a FxForward in the body of the request and the ForwardFromCurve pricing model specified in the URL:

curl -X POST "https://<your-domain>.lusid.com/api/api/instruments/capabilities?model=ForwardFromCurve"
  -H "Authorization: Bearer <your-API-access-token>"
  -H "Content-Type: application/json-patch+json"
  -d '{
        "instrumentType": "FxForward",
        "startDate": "2021-11-15T10:00:00.0000000+00:00",
        "maturityDate": "2022-05-15T10:00:00.0000000+00:00",
        "domAmount": 1000000,
        "domCcy": "EUR",
        "fgnAmount": -1200000,
        "fgnCcy": "USD"
     }'

The response contains:

  • A list of features, if available for this instrument type.

  • The metrics you can include in your valuation report.

  • The market data your recipe must be able to locate (the economicDependencies array):

}

We can see that, for this instrument type and pricing model combination, and for each day in the valuation schedule, your recipe must be able to locate:

Economic dependency type

Market data

LUSID market data store

Fx

A FX spot rate for EUR/USD

Quote Store

Discounting

A discount factor curve for EUR

Complex Market Data Store

FxForwards

A FX forward curve for EUR/USD

Note: The two Cash economic dependency types refer to currency instruments mastered in the LUSID Security Master. Since your LUSID domain is automatically provisioned with all likely currencies, you can typically ignore these dependencies.

Your recipe must contain one market data rule per economic dependency type that sets out criteria for locating suitable data in the appropriate store. See how to do this.
