Hello XARD777, you read my mind with the "Keep an eye on the White Dot on the 5min chart" quote.
This is my first post and hopes to give my two cents,

Here is my finding for pinpointing the correlations of Xu v8-SEMAFOR rev002a higher time frame dots and how they appear in the 5 minute time frame.
I have been doing a lot of backtesting and I'm getting more and more confident with Xu v8-SEMAFOR rev002a signals on lower time frames.
In this scenario, we will be looking at a 5-minute chart.

using the default colors on Xu v8-SEMAFOR rev002a indicator.
c1=(aqua & gold) c2=(snow) c3=(orange-red) c4 = (Dodger Blue)

Method - observing multiple time frames of the same pair and tracing dots based on timestamps here is what I found.
c1: is determinined by: 5min(obviously) & some but not all 15min (c1)

c2: is determined by: 15min & some 30min (c1) These snow/white-colored dots should be your first level of concern.

c3: is determined by: some 30min(c2), & 1HR & 4HR(c1) These Orange-red dots are my favorite to work off. Anything signaling from a 1HR to 4hr time frame has a lot of volume behind it. We definitely don't want to miss out on proper price action to spot the upcoming trend. Look at 1HR to 4HR S&R zones for more evaluation.

c4: is determined by: 4HR(c1), Daily (c1,c2,c3) These are the blue box around the orange-red dot. The signal is matching up with almost all dots on the daily time frame and even be a c3(orange-red) dot from the weekly!
In the picture included. These lined up all the way to the daily! and look at that sweet move.
SORRY I CHANGED THE COLORS ON MY CHART BUT I HOPE YOU GET THE IDEA

Maybe this was addressed already, but I hope this helps some folks with interpreting these signals on the 5-minute chart.
