  We give a nonuniform Berry-Esseen bound for self-normalized martingales,
which bridges the gap between the result of Haeusler (1988) and Fan and Shao
(2018). The bound coincides with the nonuniform Berry-Esseen bound of Haeusler
and Joos (1988) for standardized martingales. As a consequence, a Berry-Esseen
bound is obtained.
