there is still something i don't really understand, like inthe following situation (v23 + V19 candles),
where we have an Up Square and an Up Arrow, and where the price is obviously going down after a 1st up rallye
Of course dots have their own sub trend role, but it is a bit confusing.

for testing purpose, i am comparing with another indicator (Spike Dtetector) which also use semafors but
which clearly shows downtrend in another way (very close to xard actually).

I am starting to wonder if square and arrows have any utility left indeed (because here the arrow should indicate a major trend reversal, but it is obviously not the case, or if it is, the down reversal has not really been detected, or at least not the same way Arrow did) - even more clear by zooming out (maybe related to the horizontal range?)
