## What is the Duration of Time to Expiration?

This is the remaining life of an options contract until its scheduled expiration, a critical variable in all time-value calculations. As this duration shortens, the option's time decay, or theta, accelerates, especially for at-the-money instruments. Traders must account for this temporal erosion when structuring trades.

## What is the Horizon of Time to Expiration?

The time frame until settlement defines the investment horizon for the derivative position, influencing decisions regarding volatility expectations and hedging frequency. Longer horizons allow for strategies sensitive to long-term market trends, while shorter horizons favor high-frequency delta management. This horizon dictates the applicability of various pricing models.

## What is the Decay of Time to Expiration?

The rate at which an option's extrinsic value diminishes as the time to expiration decreases is a fundamental concept in options trading. This predictable decay benefits option sellers but erodes the value held by option buyers over time. Monitoring this rate is essential for managing the profitability of premium selling strategies.
