In this paper, we introduce the concept of the vague convergence of lo
cally integrable martingale measures in distribution, which is an orga
nic combination of the vague convergence of Radon measures and the wea
k convergence of martingales in distribution. The conditions are provi
ded for vague convergence of martingale measures. We also study the co
nvergence of stochastic integrale with respect to martingale measures
in distribution.
