Hello ssylwester,

Thank you for your post.

This is because the rollover date for the CL is not scheduled until 2/21/2011.

Please go to Tools-->Instrument Manager-->Select CL within the Available master instrument list-->Edit-->Merge Policy-->Set to "DoNotMerge"-->Click Ok.

Next please right mouse click within your chart and select "Reload all historical data".
