Gamma Capture Volatility
=
[Up/Down Barrier Width] X [Average Number Crossings in 60 Minutes]
Different Than Traditional Volatility
A tenth of 1.0% (0.10%) move in one minute is almost a 4.0% one day move. That is a big jump! For Gamma Capture, a 0.10% move represents roughly 5 extra barrier crossings. Jumps skew traditional volatility measures such as Close-Close or Parkinson's.
Volatility Trading
Money is made in trading options volatility in two ways: Buying implied volatility low and selling implied volatility high.
Delta hedging with the underlying asset over the life of the option captures the realized volatility. This is known as Gamma Scalping, Gamma Trading, or Gamma Capture. The difference between the rVol from hedging and iVol is the trader's P&L. Gamma Capture is the rVol level derived from a dynamic hedge of an option.
Up/Down Barrier Crossing
Gamma Capture utilizes a barrier crossing method to calculate intraday volatility within a 60-minute look-back window. This approach measures the degree of price variation of assets, such as the S&P 500, on how often an asset move up or down during an hour. Our system calculates a stable and accurate 1-day volatility measure, specifically designed for S&P 500 0-DTE options trading and based on options market making P&L.
Use Cases
Gamma Capture is essential for traders looking to assess risk, identify potential trading opportunities, and establish stop-loss, entry-exit levels based on volatility rather than just price. Gamma Capture Bands replace Bollinger Bands.
