Findings show that the intraday realized range based estimator performed best as compared to the daily range based and classical estimator in terms of both efficiency and bias. Results of volatility estimation and forecasting performance show that realized range based estimators seems to be more economical and efficient to estimate the ‘true’ volatility.
