Let $p$ be an odd prime number and
$E$ an elliptic curve defined over a number field
$F$ with good reduction at every prime of
$F$ above
$p$. We compute the Euler characteristics of the signed Selmer groups of
$E$ over the cyclotomic
$\mathbb{Z}_{p}$-extension. The novelty of our result is that we allow the elliptic curve to have mixed reduction types for primes above
$p$ and mixed signs in the definition of the signed Selmer groups.
