Estimating the Value-at-Risk from High-frequency Data
Data augmentation Gibbs sampler Quadratic variation Time changed Brownian motion
2016/1/27
We present two alternative approaches for estimating VaR. Both approaches are based on the observation that each trading day is very diverse and we can observe K different phases of the trading day. W...
The High-Frequency Trading Arms Race: Frequent Batch Auctions as a Market Design Response
Arms Race Frequent Batch
2015/9/18
The high-frequency trading arms race is a symptom of flawed market design. Instead
of the continuous limit order book market design that is currently predominant, we argue
that financial...
We investigate the divergence between these results and find that a virtually all of
the difference can be explained by the higher level of temporal and spatial aggregation. Since
our baseline...

Analyzing the Spectrum Asset Returns Jump Volatility Components High Frequency Data
2014/3/13
This paper reports some of the recent developments in the econometric analysis of semimartingales estimated using high frequency financial returns. It describes a simple yet powerful methodology to de...

We introduce a trade strategy representation theorem for performance measurement and portable alpha in high fre-quency trading, by embedding a robust trading algorithm that describe portfolio manager ...
High-frequency market-making with inventory constraints and directional bets
Quantitative Finance high-frequency trading, market-making limit-order book inventory risk optimisation stochastic control Hamilton-Jacobi-Bellman PNL distribution.
2012/9/14
In this paper we extend the market-making models with inventory constraints of Avellaneda andStoikov (High-frequency trading in a limit-order book, Quantitative Finance Vol.8 No.3 2008) and Gueant, L...
Optimal High Frequency Trading in a Pro-Rata Microstructure with Predictive Information
Market making limit order book pro-rata microstructure inventory risk marked point process stochastic control
2012/6/4
We propose a framework to study optimal trading policies in a one-tick pro-rata limit order book, as typically arises in short-term interest rate futures contracts. The high-frequency trader has the c...
Study on Stock Index Futures’ Mean Reversion Effect and Arbitrage in China Based on High-Frequency Data
CSI 300 Index Future High-Frequency Data Futures-Spot Arbitrage Mean Reversion Effect Mispricing Ratio
2013/2/23
Based on 1 minute high frequency data, this paper constructs no-arbitrage band for CSI300 index futures, and empirically studies the futures-spot arbitrage. Furthermore, the mean reversion and its tim...

Semimartingale Testing for jumps High frequency data Market microstructure noise Pre-averaging
2014/3/13
This paper proposes a robustification of the test statistic of Aït-Sahalia and Jacod (2009b) for the presence of market microstructure noise in high frequency data, based on the pre-averaging met...

Semimartingale Brownian motion jumps finite activity infinite activity discrete sampling high frequency
2014/3/13
This paper considers the problem of testing for the presence of a continuous part in a semimartingale sampled at high frequency. We provide two tests, one where the null hypothesis is that a continuou...
