Where the market said NO, a scar remains.

Profile tails are the footprints of violent rejection — and they are among the most readable marks the auction leaves. This chapter is about the two kinds of extremes a session can print: the ones that finished their auction, and the ones that did not.

The tail: a NO with conviction

Price probes the extreme, the aggressive response sends it back — and it never touches those prices again. On the profile, a thin line of single prints remains: the tail. A long tail is excess: the sign that the auction in that direction ended there. The longer the tail, the more emphatic the NO.

The poor extreme: a NO left unsaid

The opposite of the tail: price touches the extreme several times, flat, with no visible rejection — and the profile dies square, tail-less. A poor high or poor low is an unfinished auction: business was left pending there, and the market tends to come back to re-examine it sooner or later.

Now you can read the market's scars. One thing left: putting the whole toolkit in order — the reader's routine.
