Dissertation/Thesis Abstract

The thermodynamics of high frequency markets
by Webster, Kevin Thomas, Ph.D., Princeton University, 2014, 146; 3627279
Abstract (Summary)

High Frequency Trading (HFT) represents an ever growing proportion of all financial transactions as most markets have now switched to electronic order book systems. This dissertation proposes a novel methodology to analyze idiosyncrasies of the high frequency market microstructure and embed them in classical continuous time models.

The main technical result is the derivation of continuous time equations which generalize the self-financing relationships of frictionless markets to electronic markets with limit order books. We use NASDAQ ITCH data to identify significant empirical features such as price impact and recovery, rough paths of inventories and vanishing bid-ask spreads. Starting from these features, we identify microscopic identities holding on the trade clock, and through a diffusion limit argument, derive continuous time equations which provide a macroscopic description of properties of the order book.

These equations naturally differentiate between trading via limit and market orders. We give several applications to illustrate their impact and how they can be used to the benefit of Low Frequency Traders (LFTs). In particular, option pricing and market making models are proposed and solved, leading to new insights as to the impact of limit orders and market orders on trading strategies.
