su_posts daily post

I need that [su_post] shows me only the daily post, the post that the date o publication is today… it’s for a magazine project
the posts status are some… publish, future, any, draft, …. but no one do daily filter
I think that I need to use the meta_value variable like [su_posts post_type=”lectures” posts_per_page=”-1″ template=”templates/lectures.php” post_status=”any” order=”asc” META_VALUE=”(DATE_PUBLISH,’D/M’)=(NOW,’D/M’)”]
but I don’t know howw to write in META_VALUE=”(DATE_PUBLISH,’D/M’)=(NOW,’D/M’)” part to do this
thanks
