Python Refinitiv Data IPA Financial Contract IR Swap intra-day pricing with datetime

Dan.Camp1

I'm trying to price a SOFR swap at intra-day time periods. The documentation implies that a datetime can be provided, however, responses from the service show no valuation differences if a different time is used. See below for example code and outputs.

response = rdf.Definitions(

    universe=[swap.Definition(
        instrument_tag="Example",
        tenor="5Y",
        legs=[swap.LegDefinition(direction=swap.Direction.PAID,
                                 notional_ccy="USD",
                                 interest_payment_frequency=swap.Frequency.QUARTERLY,
                                 interest_type=swap.InterestType.FIXED,
                                 fixed_rate_percent=4.0,
                                 notional_amount=10000000,
                                ),
              swap.LegDefinition(direction=swap.Direction.RECEIVED,
                                 notional_ccy="USD",
                                 index_name="SOFR",
                                 index_tenor = 'ON',
                                 interest_payment_frequency=swap.Frequency.QUARTERLY,
                                 interest_type=swap.InterestType.FLOAT,
                                 notional_amount=10000000,
                                 spread_bp=0
                                )])
    ],
    pricing_parameters=swap.PricingParameters(valuation_date="2024-07-31T13:00:00Z",
                                              report_ccy='USD',
                                              use_legs_signing=True),
    fields=[
        "LegDescription",
        "InstrumentDescription",
        "ValuationDate",
        "FixedRate",
        "Tenor",
        "MarketValueInReportCcy",
        "ErrorMessage"
    ],

).get_data()

response.data.df

Same code, but with

valuation_date="2024-07-31T17:00:00Z"

Hi @Dan.Camp1; I'm afraid that intraday calculations are not available natively in the Refinitiv Data Library (for Python) (RDL) IPA (Instrument Pricing Analytics) module. What I mean by 'natively' is that the IPA API will not fetch intraday data to complete the calculation. For intraday calculations, all data points need to be provided for the calculation; if one is missed, you risk IPA fetching daily data. I did something similar here. For the Swap IPA module, I'm not sure that you can use the content layer. FYI: the RDL is split in three modules going from 'easiest' to 'hardest' (most deconvoluted to most convoluted), the 'Access', 'Content' and 'Delivery' layers. You may have to use the Delivery Layer. I showcase how one may do so in this article. I would advise using the delivery layer and making sure that all fields are sent in your body_parameters's "universe"; matter of fact, it may be easier using the API Playground directly as shown in that article. You may be looking into Option Contracts, in which case I would advise finding the fields to fill in here.
