限价订单簿中的羊群行为与长程记忆建模
文章 arXiv papers · 作者: Aleksejus Kononovicius et al.
总结
这项研究将细致的订单簿记录实证方法与金融羊群行为模型结合,构建订单簿动态模型。研究的目标是重现绝对收益和交易活动中的长程记忆,将交易者的集体行为与市场数据中的模式联系起来。
作者将模型的统计特征与比特币汇率和纽约证券交易所股票代码的实证特征进行比较。他们还报告称,高频绝对收益的谱密度出现断裂,可能与价格趋向均衡价格有关。摘录未说明模型方程、数据集或拟合程度,并将这一关联表述为一种可能性,而非已确立的因果结果。
核心观点
- 该模型将订单簿实证结构与金融羊群行为机制结合起来。
- 模型旨在重现绝对收益和交易活动中的长程记忆。
- 模型的统计特征与比特币汇率和纽约证券交易所股票代码进行比较。
- 高频绝对收益的谱密度断裂可能与价格趋向均衡有关。

# Order book model with herd behavior exhibiting long-range memory # Order book model with herd behavior exhibiting long-range memory In this work, we propose an order book model with herd behavior. The proposed model is built upon two distinct approaches: a recent empirical study of the detailed order book records by Kanazawa et al. [Phys. Rev. Lett. 120, 138301] and financial herd behavior model. Combining these approaches allows us to propose a model that replicates the long-range memory of absolute returns and trading activity. We compare the statistical properties of the model against the empirical statistical properties of the Bitcoin exchange rates and New York stock exchange tickers. We also show that the fracture in the spectral density of the high-frequency absolute return time series might be related to the mechanism of convergence towards the equilibrium price.
