Open Source has another dimension --J.P. Morgan's CDS Analytical Engine Available as Open Source
SDA Announces Agreement to Make J.P. Morgan's CDS Analytical Engine Available as Open Source; Increases Transparency in CDS Pricing At the centre of our current financial crisis is the CDS (credit default swap). ISDA is the trade association which draft standard contract for CDS. The market was unable to give a reasonable and authority price for CDS in recent months. The open source decision is to make the price of CDS more stable and being open source, each one could validate the price components (market risk, liquidity risk, credit risk, FX risk and others) Open source when taking a transparent perspective could help to stable a market in crisis. http://www.isda.org/press/press012909.html Antony
