We compute the Hochschild homology of the algebra of double-edge pseudo-differential operators. The double-edge algebra is naturally associated to a compact manifold whose boundary is the total space of a fibration of closed manifolds. We introduce residue-type traces on this algebra and on various of its ideals and quotients. As an application, we show that these traces are unique up to a constant. We use these traces to compute the index of Fredholm operators in the double-edge calculus.
