Credit Trader Suite of libraries aims to provide open source analytics and trading/valuation system solution suite for credit and fixed income products. To this end, it implements its functionality over 3 core libraries – CreditProduct, CreditAnalytics, and RegressionSuite, and a supporting suite of numerical libraries (FixedPointFinder and SensitivityGenerator).

The main challenges that Credit Trader Suite attempts to address are:

· Implementation of day count conventions, holidays calendars, and rule-based period generators

· Abstract the functionality behind curves, parameters, and products onto defined interfaces

· Unified/standardized methods for curve calibrations, parameter and product implementers and constructors

· Environmental system to hold live ticks, closing marks, and reference data containers

· Enhanced analytics testing

· Related suite of numerical functionality

· Ease of usage, installation, and deployment

While a number of other libraries - both Open Source implementations such as Quantlib and its variants and proprietary systems such as Fincad, NumeriX, Algorithmics, they typically cater to the needs of the wider financial mathematics community, thus diluting their value towards treating credit products. Further, few of them inherently export a curve/product/product models that work well with products quotes, marks, and reference data sources, thereby forcing development teams to build their own integration layers from scratch. Finally, building the components of functional credit-trading system requires additional layers of development over analytics.

Credit Trader Suite is an attempt to overcome these shortcomings. It aims to bring the aspects mentioned above together in one Open Source implementation that readily integrates onto existing systems.

The libraries the constitute the Credit Analytics Suite are:

· CreditProduct – Focused on the core analytics, and the curve, the parameter, and the product definitions

· CreditAnalytics – Concerned with the construction and the implementation of the interfaces defined in CreditProduct, analytics environment management, and functional distribution

· RegressionSuite – This aims to ease testing of analytics, measurement and generation of the execution time distribution, as well as release performance characterization.

· FixedPointFinder - A suite that implements a framework, as well as a comprehensive set of one-dimensional root finders.

· SensitivityGenerator - A suite that implements a) the sensitivity Jacobians of the product to the curve nodes, and b) Monte-Carlo path-dependent pay-off sensitivities.
