AB - The present paper is a continuation of [23], from which we know that the theory of traces on the Marcinkiewicz operator ideal
$ (H):= {T ∈ (H): sup_{1≤m<∞} 1/(log m + 1) ∑_{n=1}^{m} aₙ(T) < ∞}$
can be reduced to the theory of shift-invariant functionals on the Banach sequence space
$(ℕ₀):= {c = (γ_{l}): sup_{0≤k<∞} 1/(k+1) ∑_{l=0}^{k} |γ_{l}| < ∞}$.
