摘要翻译:
金融市场为研究非高斯相关动力学的交叉或首次通过时间事件提供了一个理想的框架,这主要是因为金融市场拥有大量的数据集。本文考虑了六个期货市场的逐滴答数据,导致了胖尾首次通过时间概率。用标准差对收益率进行的缩放将所有被检验的市场的概率,以及不同时间范围的概率,折叠成单一曲线,表明首次通过统计是独立于市场的(至少对于高频数据是如此)。另一方面,一个非常密切相关的量,即生存概率,在离开分布的中心和尾部时,显示出一个典型的马尔科夫动力学的双曲$t^{-1/2}$衰减,尽管市场中存在记忆。Weibull分布和Study分布的修正是在一定条件下首次通过时间性质的现象学描述的很好的候选者。所示的规模策略可能对风险控制和算法交易有用。

英文摘要:
Financial markets provide an ideal frame for the study of crossing or first-passage time events of non-Gaussian correlated dynamics mainly because large data sets are available. Tick-by-tick data of six futures markets are herein considered resulting in fat tailed first-passage time probabilities. The scaling of the return with the standard deviation collapses the probabilities of all markets examined, and also for different time horizons, into single curves, suggesting that first-passage statistics is market independent (at least for high-frequency data). On the other hand, a very closely related quantity, the survival probability, shows, away from the center and tails of the distribution, a hyperbolic $t^{-1/2}$ decay typical of a Markovian dynamics albeit the existence of memory in markets. Modifications of the Weibull and Student distributions are good candidates for the phenomenological description of first-passage time properties under certain regimes. The scaling strategies shown may be useful for risk control and algorithmic trading.
