Without knowing your "periods" formula I can't guess at what the cause of
your error might be. However I feel that the problem is only a minor
technical one rather than an insurmountable one. When the method I suggested
fails there's usually another way the formula can be written that will work
as required, or a very good reason why it will never work.

LastValue() converts a variable to a constant but it is of no use for
backtesting in the form of "LastValue(X formula)". That's where the
+PREV-PREV comes in handy.
