This paper introduces novel volatility diffusion models to account for the stylized facts of high-frequency financial data such as clustering, intra-day U-shape, and leverage effect. For example, daily integrated proposed process has a realized GARCH structure with an asymmetric effect on log-returns. To further explain heavy-tailedness data, we assume that log-returns have finite $2b$-th momen...
