That the daily number of NYSE new 52 Week Highs and the daily number of new 52 Week Lows must both be greater than 2.2 percent of total NYSE issues traded that day. That the smaller of these numbers is greater than 79. That the NYSE 10 Week moving average is rising. That the McClellan Oscillator is negative on that same day. That new 52 Week Highs cannot be more than twice the new 52 Week Lows (however it is fine for new 52 Week Lows to be more than double new 52 Week Highs). This condition is absolutely mandatory.
These measures are calculated each evening using Wall Street Journal figures for consistency. The occurrence of all five criteria on one day is often referred to as an unconfirmed Hindenburg Omen. A confirmed Hindenburg Omen occurs if a second (or more) Hindenburg Omen signals occur during a 36-day period from the first signal.
[edit] Conclusions The probability of a move greater than 5% to the downside after a confirmed Hindenburg Omen within the next 41 days after its occurrence is 77%, the probability of a panic sellout is 41% and the probability of a real big stock market crash is 25%. The occurrence of a confirmed Hindenburg Omen does not necessarily mean that the stock market will go down. On the other hand there has never been a significant stock market decline in history, that was not preceded by a confirmed Hindenburg Omen.
