# The Self-Financing Equation in High Frequency Markets

@article{Carmona2013TheSE, title={The Self-Financing Equation in High Frequency Markets}, author={R. Carmona and Kevin Webster}, journal={Capital Markets: Market Efficiency eJournal}, year={2013} }

High Frequency Trading (HFT) represents an ever growing proportion of all financial transactions as most markets have now switched to electronic order book systems. The main goal of the paper is to propose 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… Expand

Order Flows and Limit Order Book Resiliency on the Meso-Scale

- Computer Science, Economics
- 2017

It is shown that on the meso-scale the limit order flows (as well as the relative addition/cancellation rates) carry the most predictive power, and that the deeper LOB shape is more relevant on this timescale. Expand

Optimal Execution with Order Flow

- Computer Science
- 2015

It is found that temporal measures of order flow play a key role in the price formation process and it is shown how these features can be incorporated into an execution model for which closed-form solutions can be obtained. Expand
