高频金融数据中的异常等待时间

Anomalous waiting times in high-frequency financial data

Enrico Scalas, Rudolf Gorenflo, Hugh Luckock, Francesco Mainardi, Maurizio Mantelli, Marco Raberto

摘要:

在高频金融数据中,不仅回报率,而且连续交易之间的等待时间都是随机变量。因此,可以应用连续时间随机游走(CTRW)作为高频价格动态的唯象模型。对30只道琼斯工业平均指数股票的实证分析表明,高频数据的等待时间生存概率是非指数的。这一事实对基于代理的金融市场模型施加了限制。

英文摘要:

In high-frequency financial data not only returns, but also waiting times between consecutive trades are random variables. Therefore, it is possible to apply continuous-time random walks (CTRWs) as phenomenological models of the high-frequency price dynamics. An empirical analysis performed on the 30 DJIA stocks shows that the waiting-time survival probability for high-frequency data is non-exponential. This fact imposes constraints on agent-based models of financial markets.
