Patience vs. Impatience of Stock Traders
Peter Lerner

TL;DR
This paper develops a dynamic limit order book model to analyze how patience levels among traders influence market prices, execution times, and spreads, providing insights into high-frequency trading dynamics.
Contribution
It introduces a dynamic version of the Foucault, Kadan, and Kandel model to derive the distribution of bids and offers based on trader patience ratios, advancing theoretical understanding of trading competition.
Findings
Derived asymptotic distribution of bids/offers based on trader patience ratios
Simulated execution times and spreads using the dynamic LOB model
Compared model results with empirical volume-at-price data for liquid stocks
Abstract
An ability to postpone one's execution without penalty provides an important strategic advantage in high-frequency trading. To elucidate competition between traders one has to formulate to a quantitative theory of formation of the execution price from market expectations and quotes. This theory was provided in 2005 by Foucault, Kadan and Kandel. I derive asymptotic distribution of the bids/offers as a function of the ratio of patient and impatient traders using the dynamic version of the Foucault, Kadan and Kandel dynamic Limit Order Book (LOB) model. Dynamic version of the LOB model allows stylized but sufficiently realistic representation of the trading markets. In particular, dynamic LOB allows simulation of the distribution of execution times and spreads from high-frequency quotes. Significant analytic progress is made towards understanding of trading as competition for immediacy…
