Realized Covariance from High-Frequency Data Calculator

Compute the realized covariance matrix from high-frequency intraday data using 5-minute or 15-minute returns. Average over the subsampled estimator to reduce microstructure noise bias

Each component has a specific meaning:

• High-frequency intraday data — The high-frequency intraday data recorded for the scenario being assessed.

Note: Interpret the realized covariance hf result against the thresholds and context described above.

Enter the high-frequency intraday data for the scenario you are assessing. Compute the realized covariance matrix from high-frequency intraday data using 5-minute or 15-minute returns. Average over the subsampled estimator to reduce microstructure noise bias. Use the realized covariance hf result to inform your calculation.
