Levels

Murrey Math levels

A whole-chart grid of support and resistance levels from T. Henning Murrey’s system, itself derived from Gann’s work, computed over a window of bars called the Square Width.

MM Levels on INFY: a 64-day square ending today, from 0/8 at 1,000 to 8/8 at 1,250.

Using MM Levels

  1. 1Open MM Levels from Overlays and choose a Square Width.
  2. 2Click the bar the square should start on, or press ⚡ to end the square on the latest bar and get today’s levels.
  3. 3Press ◀ to step back one full Square Width at a time and see how the grid stood earlier.

Reading the grid

Unlike a single support or resistance line, Murrey Math divides the whole range into a grid of levels. It is read like the Gann octaves it came from: the outer lines are the extremes of the range and the middle line its balance point.

Questions

What is the Square Width?

The window of bars the levels are computed over. A wider square gives levels for a longer view of the range.

How are Murrey Math lines related to Gann?

Murrey built his system as a simplification of W. D. Gann’s octave divisions of price, which is why the levels fall at eighths of a range.
