Quote from Pekelo:
What you are describing is a "new" chartpattern, I call let's say "almost failed W bottom". It has been happening more and more often recently. Today's version can be seen best on the NDX chart.
Here is how it works: W bottom forms, then it fails to pass the middle level of the W and falls lower then the 2 previos bottom. But from there it rallies back forcefully.
On ES the first bottom was at 1547.50 around 2 pm and the second came 30 mins later at the same level. From there it was only be able to come up to 1549.25 and fall further back to 1546.50, below the previous 2 bottoms. And the rally came from there, going up to 1551.50...
