Fixes the CI failure in test_FractionalBacktest where indicator /= self._fractional_unit raises ValueError: output array is read-only on newer pandas.
The in-place division fails because the underlying numpy array from pandas is read-only (copy-on-write). Replaced with a non-mutating division that creates a new array and updates the list entry directly.
