You didn't get it correctly.
The specific pattern is that we made a new HOD in the last 75 minutes followed by a new LOD going into the Close.
To be fair, all I had to go on were
your words which made
no mention of a new HOD followed by new LOD in last 75 minutes of session ...
Reversing to a new low this late in the session is a fairly rare pattern.
It is indeed rare for new high
and a new low to occur not only late in the day, but anytime after 11 AM, as there is, I believe, a 92% chance that either the high or the low is in by 11 AM. It did happen, however, on May 5th, and if you go back I believe I mentioned several times high odds we make a new low before th close even as the market was trading at its highs.
But in the end, I would reiterate that
it is statistically insignificant.
Both yesterday and on May 5th and I'm sure on any other day it has happened in the past and happens again in the future there is a discernible context available before the event, and it does not depend on external distortions for explanation, though in hindsight they can be used as catalytic explanations.
For example, today is a day where I would not be surprised by the same late day high, new lows in in last hour scenario. We have the FOMC today ... might that be used as the explanatory catalyst by financial journalists and entertainers? Almost definitely! But here we are more than an hour before the open, and I can say that there is a 60/40 chance we see the high first, low last, and that while that high may occur early, it is like to happen late. So if that scenario plays out, do we say it was the result of a distortion caused by news or is it due to the technical position and condition of the market?
And, lastly, there is a 40% chance an entirely different scenario plays out.
