hindenburg omen การใช้

In 2013, a Hindenburg Omen signal was initially observed on April 5.
Because of the specific and seemingly random nature of the Hindenburg Omen criteria, the phenomenon may be simply a case of overfitting.
As a rule, the shorter the time-frame in which the conditions listed above occur, and the greater the number of conditions observed in that time frame, the stronger the " Hindenburg Omen ".
On May 31, the Hindenburg Omen again appeared; this time with proper validation in the form of three subsequent Omens occurring on June 4, June 10 and June 19 . The Omen re-emerged within the first two weeks of August in a series of six occurrences in three back-to-back sets of Omens.
