I'm keen on trading them...but the market makers seem to be sleeping, nuthin' going on there so far.
The VDax itself is a very nice product to play with though ! Once it has decided to move in one direction, it just keeps on moving and moving and moving....
The spread is something I do remember. It's terrible!
For a lot of the day it's around a full 1.00 point. Though it narrowed to around 0.35 at times.
Eurex don't really look like they can be bothered with this product and it isn't dynamic. i.e. you can't see the market depth.
I really don't know why Eurex release these new innovative products if they can't be arsed to start up a decent market making scheme and/or promote it properly.
