投机市场中的“拍卖即搜寻”理论

A Theory of 'Auction as a Search' in speculative markets

Sudhanshu Pani

摘要:

在高频订单驱动市场中,交易过程被建模为买方寻找卖方,反之亦然。在没有做市商的情况下,我们提出了一个包含限价订单和潜在订单的总订单簿模型。代理的零智能方法采用扩散漂移反应模型,通过连续拍卖(价格和数量)来解释交易。对交易价格的搜索(levy或brownian)是主要的扩散机制,其他行为动力学模型的灵感来自觅食,趋化性和机器人搜索。分析和渐近分析提供了几个场景和例子。模型的数值模拟扩展了我们对模型中布朗搜索、超扩散搜索和弹道搜索之间相对性能的理解。

英文摘要:

The tatonnement process in high frequency order driven markets is modeled as a search by buyers for sellers and vice-versa. We propose a total order book model, comprising limit orders and latent orders, in the absence of a market maker. A zero intelligence approach of agents is employed using a diffusion-drift-reaction model, to explain the trading through continuous auctions (price and volume). The search (levy or brownian) for transaction price is the primary diffusion mechanism with other behavioural dynamics in the model inspired from foraging, chemotaxis and robotic search. Analytic and asymptotic analysis is provided for several scenarios and examples. Numerical simulation of the model extends our understanding of the relative performance between brownian, superdiffusive and ballistic search in the model.
