在中国指令驱动股票市场中,限价指令需要为成交付出等待成本,如何计量限价指令的等待成交时间是金融市场流动性及微观结构理论领域崭新的研究问题。研究表明,指令生存模型能够比较精确地描述限价指令的等待成交时间概率分布,实证检验结果表明,生存模型具有比较高的准确性;同时发现限价指令等待成交时间对委托价格很敏感,而对委托量不敏感;基于委托价格的敏感性分析绘制出了限价指令等待成交时间概率分布的价格全谱图,根据该图可以预测限价指令的等待成交时间,以及为指令提交策略提供定量分析基础。
Limit order has to pay waiting cost for transaction in order market. How to measure order waiting execution time is a new theoretic problem. This paper shows that order surviving model can describe limit order transaction more precisely. We also find that limit order waiting transaction time is sensitive to price, but insensitive to volume. At last, we make out a limit-order-waiting-time probability distribution para-spectrum figure according to the sensitiveness of volume submitted, which can provide the quantity analysis foundation for order submit strategy.
