Poor High/poor Low

What is a Poor High/poor Low?

A poor high or poor low is a Market Profile judgment on the quality of a session extreme. A secure extreme shows excess: a tail of single prints where one side aggressively rejected price. A poor extreme is the opposite: the high or low is flat, with two or more TPOs of the TPO profile sitting at the same extreme price. The common reading at a poor high is that late buyers simply ran out rather than sellers forcefully taking over; a poor low mirrors that with exhausted sellers.

Poor extremes are filed under unfinished business: because the auction stalled instead of completing with rejection, the framework expects the market to revisit and repair poor highs and lows more often than tailed ones. That is a tendency the profile community trades around, not a promise; some poor extremes are never repaired.

The mechanics of formation explain the read. A tailed extreme happens when the opposing side arrives in force, responsive sellers hammering a high so hard that its prices print in only one time bracket; a poor extreme happens when the driving side simply exhausts, the last buyers finishing their business at the same tick across multiple brackets, or the session clock running out mid-auction. Nothing rejected those prices, they just stopped, and an auction that stops without rejection has not finished deciding. The same flat-extreme geometry appears in other frameworks under other names, notably as the equal highs that liquidity-based traders read as engineered stop pools, two doctrines expecting a revisit for different reasons.

Practice is bookkeeping plus caution. Unrepaired poor extremes stay marked forward, the ledger the Library's TPO levels tracker maintains alongside singles and naked POCs; repair, a later trade through or genuine re-auction of the flat price, retires the mark. The caution side concerns stops: resting orders just beyond a poor extreme sit precisely where the framework expects price to probe, which argues for structure-based placement further away. Quality reads compound at value boundaries, a poor high forming at the value area edge being both an unfinished extreme and an untested boundary at once.

How to identify poor highs and poor lows

Read the extreme's shape: tapered tails are finished business, flat ledges are not.

1. 1Build the session's TPO profile and go straight to its extremes, where the quality judgment lives.
2. 2A secure extreme tapers: a tail of single prints showing one side's aggressive rejection.
3. 3A poor extreme ledges: two or more TPOs printed at the very same extreme price, no taper, no rejection.
4. 4Mark unrepaired poor extremes forward on the chart, dated, the same ledger discipline used for naked POCs and singles.
5. 5Retire the mark on repair: a later session trading through the flat price or re-auctioning it properly closes the unfinished business.

How traders use it

• As revisit references: unrepaired poor highs and lows stay marked on the chart, much like naked POCs, and act as candidate draws when price rotates back toward them.
• As a caution flag: a poor low forming beneath a long entry warns that the low may be revisited, which argues for structure-based stops rather than stops resting just under the flat extreme.
• As part of extreme-quality reading: comparing tails against poor extremes across recent sessions to judge which range boundaries are secure and which invite retests.
• In boundary confluence: a poor extreme forming at a value area edge doubles the interest, an unfinished auction sitting exactly on the acceptance boundary, and such marks rank above poor extremes in open space.
• With flow confirmation at the revisit: when price returns to a poor extreme, delta behavior on the touch, absorption versus acceleration, decides whether the repair is completing or a new leg is launching through.
