We present photoionization spectra at optical wavelengths for hydrogen in strong parallel electric and magnetic fields for magnetic white dwarfs obtained with the complex coordinate method. It is shown that spectra calculated for fixed magnetic and electric fields can be averaged over a distribution of electric fields. Such averaged spectra are presented for fixed magnetic field with a Holtsmark distribution of electric fields at wavelengths around [FORMULA] interesting for a stationary line at [FORMULA].
