I'm old enough to remember when the ES had a pulse.
Even in 2016 ir 2017 when it had a 10 or 12 point RTH ATR for weeks at a time it would swing that whole 10 or 12 points a couple of times per session - 10 up then 10 down test the low then 10 up test the high ... recently it has been as though the entire day is lunch time except for the first 5 minutes and the last 10 minutes. Everyday is a US coil for the Euro overnight rally
