Price Volatility Filter

Definition

A price volatility filter is a mechanism or algorithm designed to mitigate the impact of extreme price fluctuations on a financial system or trading strategy. This filter typically suspends trading, adjusts operational parameters, or triggers circuit breakers when an asset’s price movement exceeds predefined thresholds within a specific timeframe. Its primary purpose is to reduce risk, prevent market cascades, and maintain orderly market conditions. Price volatility filters provide a crucial layer of protection against rapid, disruptive price shifts.
