Bitcoin Volatility Patterns, Options Greeks, and Time-Based Premium
Summary
This article links Bitcoin’s realized volatility to time-of-week and regional trading patterns, then discusses how those observations might inform options pricing and risk management. It describes a possible Saturday options-selling approach: when weekend realized activity has historically been lower, selling options early Saturday and closing before Monday could collect theta while facing less gamma exposure. It also suggests adjusting model premiums across periods with different expected move sizes.
The evidence cited is a 360-day lookback: average realized volatility was 46.84%, Saturday activity was relatively low, and most large moves occurred during European business hours. The article explains vega, delta, gamma, and theta, and introduces DVOL as a measure of 30-day implied volatility. These historical tendencies are not guarantees; the article notes that events such as a Bitcoin halving can produce elevated implied volatility even if the anticipated move does not occur. Option selling remains exposed to sharp moves and gamma losses.
Key ideas
- Historical Bitcoin activity in the cited sample was lower on weekends, especially Saturdays.
- The article proposes selling options over a quiet weekend to earn theta while managing gamma exposure.
- Implied volatility reflects expected movement, while realized volatility measures movement that occurred.
- The article identifies European business hours as the period with most large moves in its sample.
- Vega, delta, gamma, and theta describe distinct ways option values respond to volatility, price, and time.
