How can i protect a formula and still allow copy and move data?

[ALP]

i have 12 columns with data on days and each new day i want to add a new day
to the set of 12 columns without adding a 13th one. So the oldest day are
removed and the view is still 12 days.
In these columns some values are calculated with formulas from data residing
in the column (not from other columns) and i want to protect the formula but
allow the column to be moved one step to the left.
As of now i havent been able to use the built in functions of protection of
cells and protection of formulas.
Any ideas?

You could just move (copy-paste) the direct entry data i.e. the data that
isn't derived from formulas. It would be much easier if this was all grouped
together in a single easily identified block. The cells for direct data entry
should not be locked, while those with formulas are locked, then the sheet
protected.

Note, I would use copy-paste and either overwrite the data left in the final
column or delete it first before a fresh data entry. If you use cut-paste it
can affect your formulas (and strip out any cell formats) so beware!
