NanoQL.Extensions

nanoql's extensions: market conventions as XML data (calendars, day counts, indexes and the instruments' defaults), and instruments and models beyond the core. It builds on NanoQL.

dotnet add package NanoQL.Extensions

Conventions as data

Every preset nanoql ships is a record a desk can read, override and version. A file of the desk's own records is layered over the presets, and a misspelt name or a bad value is refused when the file is read:

using NanoQL;
using NanoQL.Extensions.Conventions;
using NanoQL.Time;

// TARGET with an extra holiday, over the shipped presets
File.WriteAllText("desk.xml", """
    <Conventions xmlns="https://nanoql.org/schemas/conventions">
      <Calendar name="TARGET" base="TARGET">
        <AddedHoliday>2026-12-24</AddedHoliday>
      </Calendar>
    </Conventions>
    """);
ConventionSet desk = ConventionSet.QuantLib.With(ConventionsXml.Read("desk.xml"));
Date eve = new(24, Month.December, 2026);
Console.WriteLine(ConventionSet.QuantLib.Calendar("TARGET").IsBusinessDay(eve)); // True: a business day in the presets
Console.WriteLine(desk.Calendar("TARGET").IsBusinessDay(eve));                   // False: the desk's holiday

ConventionProvider.Default = desk; makes the desk's records the defaults of every object built after it. The format and the shipped records are in the conventions guide, and the schema at nanoql.org/schemas/conventions.

How it is checked

The core's results are checked against QuantLib 1.44, using test vectors generated by QuantLib's Python package and by QuantLib built from source; the extensions ported from QLNet are checked against QLNet 1.13.2. What the checks cover, per module, is on the validation page.
