euro yeald curve

[marameo]

Hi,

I am interest in trading the german yeald curve with a butterfly such long 5yr short 10yr twice and buy the 30yr.

When I chart this kind of trade on a 5 year period I see drift and I am wondering if its because of the change in the CTD:

I know that a 1:2:1 ratio may not be neutrals to the yeald..

thanks

The same goes for the NOB spread...here I chart with a continuos front month conrtract; does that drift happen during trading or at rolling time?
