Higher-order error estimates of the discrete-time Clark--Ocone formula
Tsubasa Nishimura, Kenji Yasutomi, Tomooki Yuasa · 2021-01-18 · via math.PR updates on arXiv.org

In this article, we investigate the convergence rate of the discrete-time Clark--Ocone formula provided by Akahori--Amaba--Okuma [1]. In that paper, they mainly focus on the $L_{2}$-convergence rate of the first-order error estimate related to the tracking error of the delta hedge in mathematical finance. Here, as two extensions, we estimate "the higher order error" for Wiener functionals with an integrability index $2$ and "an arbitrary differentiability index."
