## Why Does Theta Decay Accelerate as an Option Approaches Expiration?

Theta decay accelerates because the value of the option's extrinsic (time) value becomes increasingly sensitive to the passage of time as expiration nears. With little time left, the probability of a significant price move is low, and the option's premium rapidly collapses to its intrinsic value.

This rapid collapse is reflected in the non-linear, accelerating rate of Theta decay.

### [Selling Options near Expiration](https://learn.greeks.live/area/selling-options-near-expiration/?utm_source=crypto.greeks.live&utm_medium=referral&utm_campaign=satellite)

Strategy ⎊ Selling options near expiration is a high-Theta trading strategy where a derivatives trader systematically sells contracts with a short time until maturity to capitalize on the rapid acceleration of time decay.

### [Theta Decay](https://learn.greeks.live/area/theta-decay/?utm_source=crypto.greeks.live&utm_medium=referral&utm_campaign=satellite)

Time Decay Quantification ⎊ Theta measures the rate at which an option's value decays due to the passage of time, representing the daily loss in extrinsic value for the option holder, assuming no change in the underlying price or volatility.

This abstract rendering powerfully symbolizes the final settlement dynamics of complex financial instruments operating on novel distributed ledger technologies. The core concept explores the high-frequency interaction between physical system analogues and digital derivatives markets, specifically focusing on the rapid decay of theta erosion as expiration approaches. The robust yet transparent interface suggests secured data flow, critical for maintaining decentralized autonomous organization governance in leveraged trading scenarios. The glowing outer ring evokes the premium paid for out-of-the-money calls momentarily flashing into profitability near expiry. This juxtaposition models the challenge of accurately pricing exotic derivatives where path dependency significantly influences the final payoff structure, demanding rigorous VaR calculation across nascent crypto asset classes."
