OpenGamma - avoid it

<t>I recently downloaded OpenGamma source code. As a quick check: I search for the string "Rebonato" in the source code. Nothing came up. Maybe I need to have commercial version?I would think that, a model library with decent rates model and decent documentation would have Rebonato in source code / ...

The pv of that can be shown as forwardStartingAnnuity*(mktFwdRate2y2y - strike), which can be computed using today's mkt rate curve (an...

I was about to give the following argument for why the answer is 1/13 (my argument might simply be a longer version of what you meant in your most recent post ):By the standard CLT argument, Zn=(Yn-n*mu)/(sqrt{n}*sigma) (where mu=7/2 and sig...
