Impact and Volatility in Order-Driven Markets
We argue that on electronic markets, competition between liquidity providers should reduce the spread until the execution cost using market orders matches that of limit orders. This implies a linear relation between the bid-ask spread and the average impact of market orders, in good agreement with our empirical observations. We then use this relation to justify a strong, and hitherto unnoticed,...
متن کاملImpact and Volatility in Double Auction Markets
We argue that on electronic markets, limit and market orders should have equal effective costs on average. This symmetry implies a linear relation between the bid-ask spread and the average impact of market orders. Our empirical observations on different markets are consistent with this hypothesis. We then use this relation to justify a simple, and hitherto unnoticed, proportionality relation b...
متن کاملRelation between volatility correlations in financial markets and Omori processes occurring on all scales.
We analyze the memory in volatility by studying volatility return intervals, defined as the time between two consecutive fluctuations larger than a given threshold, in time periods following stock market crashes. Such an aftercrash period is characterized by the Omori law, which describes the decay in the rate of aftershocks of a given size with time t by a power law with exponent close to 1. A...

Therefore market participants should always measure the liquidity of the markets, which they can carry out in two ways, in a static and in a dynamic form. The most commonly used liquidity measures – bid-ask spread and the turnover...
متن کاملVolatility Discovery across Stock Limit Order Book and Options Markets
