Nigel Eccles (the CEO of HubDub) and Robin Hanson (the inventor of MSR) have some explaining to make about the extreme zigzagging of the Barack Obama event derivative (in blue on this static compound chart). Look at the right end of the chart.

UPDATE:

Nigel Eccles:

There was a bug in that chart which is now fixed. However the excess volatility is still there. The problem is that our early markets were created with a liquidity parameter which was too low. That is fixed with more recent markets. However we are also looking at modifying the MSR in some significant ways.
