Instantaneous Impact Function

Impact

The Instantaneous Impact Function, within cryptocurrency derivatives and options trading, quantifies the immediate price adjustment resulting from a discrete event, such as a trade execution or a news announcement. It represents the difference between the pre-event price and the post-event price, effectively capturing the initial market reaction. This function is particularly relevant in high-frequency trading environments and for assessing the effectiveness of order routing strategies, providing a granular view of price discovery. Understanding this impact is crucial for risk management, especially when dealing with volatile assets and complex derivative structures.
