Why not accept the fact that you have no data to base a trend on and
forget about it during the first 30 days?

Or, a similar approach, change your script each day during those 30 days
to create a 1, 2, 3, 4, ... 30 day trend ?


If at all possible, the best you can get is something that may look like
a 30-day trend but is not.
