We investigate the effect of the order canceling rule in the trading model of financial exchanges. This study employs a stochastic order-book model. Such models are widely used to study the relation between price fluctuation and price formation in continuous double auction. The model herein incorporates simple mechanisms such as limit order and trading rules without considering investors' strategies. It captures the transaction structure used in financial exchanges. Using three simple stochastic order-book models, we indicate the comparative analysis of the effectiveness of the cancel order.
IntroductionMajor financial exchanges employ continuous double auctions wherein sellers and buyers simultaneously present respective prices. To determine the relation between price formation and price fluctuation, scholars use stochastic order-book models, which replicate transactions occurring under mechanisms customarily used in financial exchanges. In particular, Maslov's proposal is a good example of its pioneering model [1]. In this model, limit and market order were chosen with equal probability. Bid and ask orders were chosen with equal probability as well. The limit order price was selected by a uniform random number within a specified range from the transaction price. By doing so, he captured the power law in the distribution of price differences gathered via simulations. Since the publication of this model, various stochastic order-book models have been proposed [2,3].
