模拟股票市场中的等待时间

Waiting Times in Simulated Stock Markets

Alessandro Cappellini, Gianluigi Ferraris

摘要:

利用一个证券交易所的精确复制模型,以等待时间分布为评价指标,通过改变运营商行为和市场微观结构,对连续双向拍卖(CDA)机制的36种不同设置进行了检验。研究结果表明,尽管米兰证券交易所在配置角度下的效率略高于纽约证券交易所,但CDA仍然能够清除强烈不同的订单流,这证明了股票市场的内在复杂性。模拟已建成一个基于代理的模型,以获得一个合理的订单流。单个代理人的决策及其通过市场账簿的相互作用是现实的,并再现了一些实证分析结果。所述结果是通过分析完整的待决时间序列和单独地对要价和出价序列进行相同的计算而获得的。

英文摘要:

Exploiting a precise reproduction of a stock exchange, the robustness of the Continuous Double Auction (CDA) mechanism, evaluated by means of the waiting time distributions, has been proved versus 36 different set ups made by varying both the operators' behaviour and the market micro structure. The obtained results demonstrate that the CDA remains able to clear strongly different order flows, though the Milan stock exchange seemed to be a little more efficient than the NYSE under the allocative point of view, witnessing the intrinsic complexity of the stock market. The simulation has been built as an Agent Based Model in order to obtain a plausible order flow. The decisions of single agents and their interaction through the market book are realistic and reproduce some empirical analysis results. The mentioned results have been obtained either by the analysis of the complete pending time series and the same computation of the asks and bids series alone.
