高频市场流动性的多尺度表征

Multi-scale Representation of High Frequency Market Liquidity

Anton Golub, Gregor Chliamovitch, Alexandre Dupuis, Bastien Chopard

摘要:

我们引入了一个基于事件的框架的方向性变化和超调映射到所谓的内在网络的连续金融数据-基于状态的离散化的内在解剖时间序列。定义了一种方法的状态收缩的内在网络,我们表明,它有一个一致的层次结构,允许多尺度分析的金融数据。我们定义了一个信息理论的测量称为流动性,其特点是不可能的价格轨迹,并认为新的度量有能力检测和预测压力在金融市场。我们展示了外汇市场的实证例子,新的措施不仅量化流动性,而且还作为一个早期预警信号。

英文摘要:

We introduce an event based framework of directional changes and overshoots to map continuous financial data into the so-called Intrinsic Network - a state based discretisation of intrinsically dissected time series. Defining a method for state contraction of Intrinsic Network, we show that it has a consistent hierarchical structure that allows for multi-scale analysis of financial data. We define an information theoretic measurement termed Liquidity that characterises the unlikeliness of price trajectories and argue that the new metric has the ability to detect and predict stress in financial markets. We show empirical examples within the Foreign Exchange market where the new measure not only quantifies liquidity but also acts as an early warning signal.
