[TYPO3-english] I want news to disappear from LATEST list

[Sergio]

Hi list, 

I've got two tt_news lists on my site: one LATEST and one LIST.

I've ordered my LATEST list by "datetime asc" using the "listOrderBy"
attribute and I just want the articles disappear from this list when the
article's date passed. However, I just don't want articles disappear
from the LIST list.

I didn't find any field on tt_news manual to solve my problem.

Any help?

Sergio
