Lagged Price Series
A lagged price series is a dataset where price observations are shifted by one or more time periods to facilitate statistical comparison. By aligning the current price with its value at a previous interval, analysts can calculate correlations and test for lead-lag relationships between different assets or within the same asset.
This technique is fundamental for identifying trends and testing the efficiency of the market. In the context of crypto derivatives, lagged series are used to analyze how futures prices respond to changes in the underlying spot price.
It helps in identifying arbitrage opportunities and understanding how information propagates through the order book. This structural view of price movement allows for the development of predictive models that account for delays in market reaction.
It is a basic yet powerful tool for quantifying the speed of price discovery in various trading venues.
