Out-of-sync trading is one of the important topics in the financial high-frequency data processing. In this paper, the unsynchronized trading models of financial securities given in [1] and [2] are generalized, and the statistical models of observable returns are investigated in the extended model. Finally, the parameter estimation of the model is given.
