I heard DAX moves very quick. But normally how fast and how large can it move? Is it even scarier than HSI? HSI is worth HKD50 (~USD6.5) per 1 point. It may move by 1XX-2XX points (once 3XX) in a matter of less than 1 minute. The cost is ~USD1282 for 200 points. So far, I couldn't find any instrument which can beat this monster.
