## Volatility Estimators

Volatility estimators are mathematical formulas used to calculate the volatility of an asset based on observed price data. These range from simple standard deviation of returns to more sophisticated estimators like Parkinson or Garman-Klass.

These estimators utilize different price points, such as open, high, low, and close, to provide a more accurate picture of volatility than close-to-close measures alone. In high-frequency trading, selecting the right estimator is crucial for capturing intraday volatility dynamics.

They allow traders to get more information out of the same amount of price data. Some estimators are designed to be more robust against outliers or noise in the market.

By choosing an appropriate estimator, market participants can better refine their pricing and risk management strategies. They are essential tools for anyone involved in market making or derivative trading.

Proper use of these estimators can lead to a significant competitive advantage in execution. They bridge the gap between raw data and actionable risk metrics.
