We investigate the structure of the second-order spatial differential structure of optic flow for the case of a rigid surface in parallel projection. We disregard such problems as that of noise and that of how to obtain optic flow from image flow in the first place. The focus of the investigation is on the essential geometric structures.

Retail Order Flow Segmentation
The Journal of Trading, 2018In August 2012, the New York Stock Exchange launched the Retail Liquidity Program (RLP), a trading facility that enables participating organizations to quote dark limit orders executable only by retail traders. A Hasbrouck (1991) structural vector autoregression shows that the facility increased the information content of the order flow by ...

We provide new evidence on the relation between order flow and prices, an issue that is central to asset pricing and market microstructure. We examine proprietary data on a broad panel of NYSE-listed stocks that reveal daily order imbalances by institutions, individuals, and market makers.

Quotes, Order Flow, and Price Discovery
The Journal of Finance, 1997ABSTRACTThe goal of this article is to examine the impact of 1975 Congressional mandate to integrate the trading of NYSE‐listed stocks. The conclusions are: most of the time, the New York Stock Exchange (NYSE) quote matches or determines the best displayed quote, and the NYSE is the most frequent initiator of quote changes.

Order flow and volatility: An empirical investigation
Journal of Empirical Finance, 2014We study the relationship between order flow and volatility. To this end we develop a comprehensive framework that simultaneously controls for the effects of macro announcements and order flow on prices and the effect of macro announcements on volatility. Using high-frequency 30-year U.S.

We consider the Linear-Quadratic-Regulator (LQR) problem in terms of optimizing a real-valued matrix function over the set of feedback gains. Such a setup facilitates examining the implications of a natural initial-state independent formulation of LQR in designing first order algorithms.

SSRN Electronic Journal, 2016In August 2012, the New York Stock Exchange launched the Retail Liquidity Program (RLP), a new trading facility that enables participating organizations to quote dark limit orders available only to retail traders. The facility increased the information content of the order flow by distinguishing retail trades from relatively more informed trades ...

Order flow is toxic when it adversely selects market makers who may be unaware that they are providing liquidity at a loss. In [10] the VPIN metric as an estimator of order flow toxicity based on volume imbalance and trade intensity was introduced. Here another basic procedure to measure order flow toxicity based on all available information about ...

Order flow and exchange rate comovement
Journal of International Money and Finance, 2017Abstract This paper extends the literature on the linkage between order flows and exchange rates from the univariate to the multivariate framework. We examine how order flow differentials drive exchange rate comovements using data on five major exchange rates and at three different intraday frequencies.

Second Order Variational Optic Flow Estimation
2007In this paper we present a variational approach to accurately estimate the motion vector field in a image sequence introducing a second order Taylor expansion of the flow in the energy function to be minimized. This feature allows us to simultaneously obtain, in addition, an estimation of the partial derivatives of the motion vector field.
