Short term market changes happened very quick, few days or even one-day data may suggest the change. Hurst parameter need large amount data to do the calculation, obviously much more than few days. This statistical behavoir of the hurst parameter prevented Hurst parameter to do short term prediction. But, Hurst parameter is powerful to distinguish the market from true random walk.
野狐禅JJ的意思是说市场经常在短期内发生大的变化,而HURST处理需要大量的数据(言外之意是需要一定历史数据,需要一定长的时间啦)但HURST值已经可以证明随机漫步是立不住脚的.大致意思是这样吗?
