iCDS is a SNAC (Standard North American CDS) upfront fee calculator built on the ISDA Standard CDS Model. It mirrors the indicative-pricing workflow originally found on the Markit Partners CDS calculator.
The app is free. Its only objective is for the author to have a non-trivial application in the iPhone App Store.
It recalculates the upfront fee and intermediate results live as you change inputs — using quick-entry controls or the pickers reached by tapping the input buttons.
Background
I started this project when as a ‘former’ Mac developer I was swept up by the excitement of the iPhone App phenomenon. This led me to a drive to get a non-trivial application into the App Store. I convinced my family to buy me a MacBookPro for my birthday in Sept, 2009 and about 20 hours of effort latter I had my first GUI prototype running on the simulator.
Along the way I have learned a lot about the rich environment of information sharing now happening in the development community. I was re-introduced to the Apple Development Tools (XCode) and the Snow Leopard OS. Not having touched MPW(Macintosh Programmers Workshop) in over 15 years, it was like I never left home with the added power of the underlying LINUX environment that I am well versed in using every day at work. I then was introduced to new resources including ITunes U, blogs and code.google.com.
