TWAP Settlement Design

Mechanism

The time-weighted average price settlement design functions as a deterministic protocol for calculating the final strike or settlement value of a derivative contract by aggregating index prices over a predefined temporal window. By sampling market data points at consistent intervals, this structure mitigates the impact of transient volatility or localized flash crashes on the underlying asset. It effectively smooths the settlement reference, ensuring that participants are not disproportionately penalized by instantaneous price spikes that deviate from the broader market consensus.
