Does anyone trade Euro Bund future FGBL or FGBM on Eurex ?

Many people talk here about mini Nasdaq , mini SP500 or EuroStoxx 50.
I wonder why nobody trade them.
This future seems to be great :
High volume : 800 000 for FGBL and 500 000 for FGBM by day
1 tick = 0.01 = 10 Euro
big move = 30 ticks

That's how I make my living. Eurex and CBOT. Bunds and Bonds. Trade 'em any way you see fit.

 

I trade them as a spread / also tbonds vs tnotes
