Over a year ago I wrote here about a library I had written to work out the implied interest rates available on Intrade. This library was originally envisioned as a cloud application built on top of the Google App Engine, but I couldn’t get it working on that platform. I recently tried again and now it works! The application is called Iminra - Implied Interest Rates on Intrade.
Update: Intrade has now shutdown with financial irregularities. So I have shutdown Iminra too.
