# Murrey Math Levels A Support/Resistance & Levels concept (Exotic level systems) in the LuxAlgo Library, with 1 indicator implementation. ## What are Murrey Math Levels? Murrey Math levels are an algorithmic grid of nine horizontal lines, 0/8 through 8/8, dividing a reference frame of price into eighths, with overshoot lines at +1/8 and +2/8 above and -1/8 and -2/8 below. T.H. Murrey published the system in the 1990s as a mechanical restatement of Gann's habit of dividing price into eighths: the frame is derived from the recent high-low range, snapped to a scale that subdivides powers of ten into halves, quarters, and eighths to suit the instrument's magnitude. The grid therefore recomputes itself as new frames complete instead of depending on hand-drawn judgment. Murrey's mid-1990s book presented the system as Gann simplified for ordinary traders: where Gann's price-time work demands judgment at every step, Murrey Math fixes the octave arithmetic so that any two users of the same settings see the same nine lines. That mechanical honesty is the system's real innovation, and it is also why the grid behaves like a utility rather than a theory; the lines are where the arithmetic puts them, meaningful only insofar as price treats them as references. Each line has a conventional role in Murrey's vocabulary: 0/8 and 8/8 are the strongest support and resistance; 4/8 is the major pivot separating bullish from bearish territory; 3/8 and 5/8 bound the congestion band where the system expects price to spend much of its time; 2/8 and 6/8 are strong reversal candidates; 1/8 and 7/8 are weak stall levels. These labels are conventions of the system, not verified statistics, and like [Gann Square-of-9 levels](https://www.luxalgo.com/library/concept/gann-square-of-9-levels/) the grid earns trust only where price actually reacts to it. The practical variables are the frame and the snap. Implementations differ in the lookback that defines the frame's high and low (with 64 bars a common convention) and recompute the grid when price escapes or a new frame completes, so levels jump rather than drift; the snapped scale means lines sit at clean fractions that often coincide with round numbers. As with any formula grid, standing rises with confluence: a 4/8 that lands on a [prior period level](https://www.luxalgo.com/library/concept/prior-period-levels/) or a well-tested [S/R zone](https://www.luxalgo.com/library/concept/s-r-zone/) is a stronger reference than an eighth line alone. ## How to read Murrey Math levels on a chart The grid draws itself; reading it means knowing each line's conventional role and validating against actual reactions. 1. Apply the indicator and note its frame settings: the lookback defining the range (64 bars is a common default) and the octave scale it snapped to. 2. Locate 4/8 first: the midline is the system's bull-bear pivot, and price's side of it sets the conventional bias. 3. Mark the extremes: 0/8 and 8/8 are the frame's strongest support and resistance, with the +/-1/8 and +/-2/8 overshoot octaves beyond them. 4. Note the congestion band: 3/8 to 5/8 is where the system expects rotational trade, so range tactics apply inside it. 5. Validate before trusting: track how price actually behaves at 2/8, 4/8, and 6/8 on the instrument; a grid that draws reactions earns weight, one that price ignores is decoration. 6. Expect recomputes: when price accepts beyond the frame or a new frame completes, the whole ladder jumps to new prices by design. ## How traders use it - As a range map: fade approaches to 2/8 and 6/8 back toward 4/8 while price rotates inside the frame, and stand aside or switch to breakout tactics when price closes beyond 0/8 or 8/8 into the overshoot octaves. - As a bias line: above 4/8 favor longs toward 5/8 and 6/8, below it favor shorts, treating 4/8 the way midpoint traders treat the middle of any established range. - As confluence: a Murrey line coinciding with a prior high, a volume shelf, or a session level carries more weight than the grid alone, and distance from 4/8 is sometimes read oscillator-style as a stretch measure. - As a level ladder for management: entries at one octave line are staged against the next, stops beyond the line behind, targets at the line ahead, standard [level interaction](https://www.luxalgo.com/library/concept/level-interaction-rules/) mechanics applied to a fixed grid. - As a cross-check against session formulas: comparing the grid with [floor pivots](https://www.luxalgo.com/library/concept/floor-pivots/) or [Camarilla](https://www.luxalgo.com/library/concept/camarilla/) levels finds the prices where independent arithmetic agrees, the same confluence habit used with measured levels. ## Murrey Math vs other formula grids - **Floor Pivots** (https://www.luxalgo.com/library/concept/floor-pivots/): Floor pivots recompute each session from the prior period's high, low, and close, landing wherever that arithmetic says. Murrey lines snap a frame onto fixed octave fractions, so they sit at clean scale divisions and persist until the frame itself changes. - **Camarilla** (https://www.luxalgo.com/library/concept/camarilla/): Camarilla levels multiply the prior day's range by fixed coefficients around the close, tuned for intraday fades. Murrey's ladder is frame-based rather than session-based, with a vocabulary of roles per line instead of a fade-at-H3/L3 playbook. - **Fib Retracement** (https://www.luxalgo.com/library/concept/fib-retracement/): A retracement measures a chosen swing and inherits its anchors' subjectivity. Murrey Math removes the choosing: the frame algorithm picks the range and the eighths are fixed, trading measurement nuance for mechanical repeatability. ## FAQ ### How are Murrey Math levels different from pivot points? [Floor pivots](https://www.luxalgo.com/library/concept/floor-pivots/) and [Camarilla](https://www.luxalgo.com/library/concept/camarilla/) recompute every session from the prior period's high, low, and close, so their levels land wherever that arithmetic says. Murrey Math instead snaps a recent range onto a fixed price scale divided into eighths, so its lines sit at clean fractions of the frame and only move when a new frame is established. Both are mechanical; neither is predictive by itself. ### What do the +2/8 and -2/8 Murrey Math lines mean? They are the overshoot octaves, extensions one and two eighths beyond the normal 0/8 to 8/8 frame. The system labels price above 8/8 as extremely overbought and prone to snap back inside the frame, with the mirror reading below 0/8. Sustained acceptance in the overshoot zone typically prompts the algorithm to recompute the frame at the new scale instead. ### What lookback should the Murrey Math frame use? The convention most implementations inherit is a 64-bar frame, with 32, 128, and 256 as the usual alternatives, powers of two fitting the octave arithmetic. Shorter frames re-anchor often and track recent trading tightly; longer frames give stabler, more structural lines. As with any parameter grid, the honest procedure is to fix one setting and judge whether price respects its lines. ### Is Murrey Math just repackaged Gann analysis? It is openly derived from Gann's eighth-divisions, and Murrey marketed it as Gann made mechanical. The difference is operational: Gann work involves judgment about anchors, angles, and time, while Murrey Math is an algorithm anyone can reproduce. Whether the mechanization preserves whatever value Gann's method had is exactly the open question; what it certainly preserves is repeatability. ### Is there evidence behind the octave labels like '2/8 strong reversal'? No published, rigorous statistics support the per-line roles; they are conventions from Murrey's system description, repeated through trading content. Some lines coincide with round numbers and prior structure often enough to attract genuine order flow, which can make the labels locally self-fulfilling. The defensible use is empirical: test reactions per line on your instrument before assigning any line authority. ### Which markets does Murrey Math suit? The snapping arithmetic assumes prices that live comfortably on decimal octaves, and the system grew up on equities and futures at daily scale, where its frames and round-number coincidences behave most naturally. It runs anywhere, and forex and crypto users apply it intraday, but instruments with extreme price scales or constant 24-hour drift give the frame logic more trouble, and validation-by-reaction matters even more there. ## Implementations in the Library - Murrey Math Levels (LuxAlgo): https://www.luxalgo.com/library/indicator/murrey-math-levels/ ## Related concepts - Gann Square-of-9 Levels: https://www.luxalgo.com/library/concept/gann-square-of-9-levels/ - DiNapoli Levels: https://www.luxalgo.com/library/concept/dinapoli-levels/ - Tirone Levels: https://www.luxalgo.com/library/concept/tirone-levels/ --- Source: https://www.luxalgo.com/library/concept/murrey-math-levels/ (LuxAlgo Library, the encyclopedia of trading & technical analysis).
