HOD Pump and Dump To LOD Set Up

I have been backtesting a setup on the 15 minute chart where price grinds/spikes higher and engulfs at the High of Day only to dump down to the Low of Day.

I notice there are three variations of this pattern

It blows through the Low of day and makes a substantial lower low

It just barely takes out the Low of day

It comes just shy of the Low of day and DOES NOT take it out

Comment:

This is a 3 session set up where Asia and London form the higher lows and pump up only for New York to commensurate with the dump down.

These are all 15 minute charts of the entire trading day

Here is today, Monday May 13th on the 5 minute chart
