-------------------------------+--------------------------------------------
Root numbers for elliptic curves are currently only implemented via Pari
(pari(E).ellrootno()) and only over the rational numbers.
We (Tim Dokchitser's group at Sage Days 22) intend to add the possibility
to compute local and global root numbers for elliptic curves over number
fields. A first patch may not fully implement the case of additive
reduction over primes dividing 2 or 3.
