Non-Linear Decay Function

Function

This describes a mathematical relationship used to model the time-value erosion of an option where the rate of change is not constant, diverging from simple linear or standard Black-Scholes theta decay. Such functions are often employed to better capture the accelerated premium decay observed in options with very short time horizons or those sensitive to sudden shifts in implied volatility. Traders utilize this to precisely time entry and exit points for theta harvesting strategies.
