Since the papers about realized volatility calculate daily volatility out of intraday data, is it also possible to apply same methods to calculate e.g. 10 minutes volatility by smaller sampled data e.g. by 1 second returns? I could not find a single paper about that. Specifically, I'm interest if methods which remove microstructure noise, such as kernels, are still valid.

  • $\begingroup$ They actually do, since the noise creates autocorrelation in the price process which is removed by the kernel. e.g. onlinelibrary.wiley.com/doi/10.3982/ECTA6495/abstract $\endgroup$
