# Poor High/poor Low A Volume & Order Flow concept (Market profile / auction theory) in the LuxAlgo Library. ## 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](https://www.luxalgo.com/library/concept/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](https://www.luxalgo.com/library/concept/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](https://www.luxalgo.com/library/concept/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](https://www.luxalgo.com/library/concept/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. Build the session's TPO profile and go straight to its extremes, where the quality judgment lives. 2. A secure extreme tapers: a tail of single prints showing one side's aggressive rejection. 3. A poor extreme ledges: two or more TPOs printed at the very same extreme price, no taper, no rejection. 4. Mark unrepaired poor extremes forward on the chart, dated, the same ledger discipline used for naked POCs and singles. 5. Retire 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](https://www.luxalgo.com/library/concept/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](https://www.luxalgo.com/library/concept/volume-delta/) behavior on the touch, absorption versus acceleration, decides whether the repair is completing or a new leg is launching through. ## Poor extremes vs related profile structures - **Single Prints** (https://www.luxalgo.com/library/concept/single-prints/): Complementary diagnoses from the same lens: a tail of singles at the extreme is excess, the auction finished by rejection, while a flat multi-TPO ledge is its absence. Singles mid-profile mark speed; poor extremes mark exhaustion; both are unfinished business, differently shaped. - **Unfinished Business** (https://www.luxalgo.com/library/concept/unfinished-business/): The umbrella category: auction events that ended without resolution and are expected to be revisited more often than resolved ones. Poor extremes are the flagship member, alongside singles and naked POCs, and the revisit expectation is the family's shared, and only, promise. - **TPO Profile** (https://www.luxalgo.com/library/concept/tpo-profile/): The instrument that makes the judgment possible: poor versus secure is read from TPO counts at the extreme price, a distinction bar charts blur and volume profiles read differently. No TPO construction, no poor-extreme vocabulary. ## FAQ ### What makes a high or low poor in Market Profile? Lack of excess. Instead of a single-print tail showing aggressive rejection, the extreme is a flat ledge with two or more TPOs at the very same price. It reads as the aggressor exhausting itself rather than the other side rejecting value, which leaves the auction at that extreme unfinished. Exact TPO-count conventions vary slightly by practitioner. ### Do poor highs and poor lows always get repaired? No. Repair, meaning a later revisit that trades through or re-auctions the flat extreme, is treated as a higher-odds tendency in the auction framework, not a rule. Strong trends can leave poor extremes behind for long stretches, so traders use them as context and targets with defined risk rather than as standalone signals. ### How does a poor high differ from equal highs? Same geometry, different doctrine. The flat double-touch extreme reads in Market Profile as an exhausted, unfinished auction, and in liquidity-based frameworks as engineered equal highs with a stop pool resting above. Both expect the level to be revisited, one to finish the auction, the other to harvest the stops, which is why the two vocabularies so often mark the same price for the same eventual event. ### What exactly counts as repair? A revisit that resolves the unfinished auction: price trading decisively through the flat extreme, or returning to re-auction those prices with genuine two-sided rotation rather than a single wick. Once repaired, the mark retires, the level's special status spent. A touch that instantly rejects without trading through is ambiguous, and practitioners differ on whether it counts, another of the framework's convention boundaries worth fixing personally and keeping. ### How long do poor extremes stay relevant? The freshness logic of all profile references applies: recent poor extremes near current price are live candidates for the next rotation, while months-old marks from different volatility regimes mostly document history. Session extremes matter for days to weeks; poor extremes on composite or weekly profiles carry proportionally longer. The ledger stays honest by retiring repaired marks promptly and demoting stale ones. ### Should stops rest beyond a poor extreme? The framework's own logic argues no: a poor extreme is precisely where a revisit probe is expected, so stops parked just past the flat ledge sit in the probable path of the repair. The alternatives are structural, placing invalidation beyond levels whose breach genuinely changes the trade's thesis, or accepting the poor extreme's revisit as scenario and sizing so the probe is survivable. Resting where the doctrine predicts traffic is the one clearly dominated choice. ## Related concepts - Initial Balance: https://www.luxalgo.com/library/concept/initial-balance/ - TPO Profile: https://www.luxalgo.com/library/concept/tpo-profile/ - Single Prints: https://www.luxalgo.com/library/concept/single-prints/ - Unfinished Auction: https://www.luxalgo.com/library/concept/unfinished-auction/ - Excess: https://www.luxalgo.com/library/concept/excess/ - Balance vs Imbalance: https://www.luxalgo.com/library/concept/balance-vs-imbalance/ - Rotation Factor: https://www.luxalgo.com/library/concept/rotation-factor/ - One-timeframing: https://www.luxalgo.com/library/concept/one-timeframing/ - Day-type Taxonomy: https://www.luxalgo.com/library/concept/day-type-taxonomy/ - Value Migration: https://www.luxalgo.com/library/concept/value-migration/ --- Source: https://www.luxalgo.com/library/concept/poor-high-poor-low/ (LuxAlgo Library, the encyclopedia of trading & technical analysis).
