Murrey Math Lines (MML)
Murrey Math Support & Resistance (How to Read the 1/8 Lines)
How Murrey Math Lines convert Gann’s “octaves” into eight price levels, what each 1/8 band means for support and resistance, how the core trading range (3/8–5/8) behaves, and how extended octaves (+1/8, +2/8, −1/8, −2/8) signal when a new Murrey frame is being printed.

What Are Murrey Math Lines (MML)?
According to Gann theory, prices often move in “octaves”—repeating harmonic ranges.
Murrey Math Lines translate this idea into eight bands, each representing 1/8 of the trading range.
Each 1/8 band acts as a potential support or resistance level.
When we assign different behavioral characteristics to these octaves, every Murrey line gets its own role in how price moves, stalls, or reverses.
8/8 and 0/8 Lines — Ultimate Support & Resistance
• The 8/8 and 0/8 lines are considered the hardest levels for price to break.
• On the way up, 8/8 often acts as the most important resistance.
• On the way down, 0/8 often provides the most important support.
• Price will frequently reject these lines on the first test rather than cleanly breaking through.
7/8 Line — Weak, Stall & Reverse
• The 7/8 line is a weaker resistance band.
• If price rallies very quickly and then stalls at 7/8, a fast reversal back down is common.
• If price does not stall at 7/8, it often continues to push toward the stronger 8/8 level above.
Main-Heading 2: Mid-Range Lines & Reversal Pivots
The middle Murrey levels shape the “normal” trading range. Some of them are classic reversal pivots, while others define the core band where price spends most of its time. Understanding 6/8, 5/8, 4/8, 3/8, and 2/8 helps you anticipate whether price is likely to bounce, range, or break into a new zone.
5/8, 4/8, 3/8 — Trading Range Structure
5/8 Line (Top of the Trading Range)
• Price typically spends about 40% of the time oscillating between 5/8 and 3/8.
• If price moves above 5/8 and stays there for a while, the market is said to be trading in a “premium” zone relative to what buyers normally want to pay.
• Price can remain above 5/8 in this premium area, but if it drops back below 5/8, it often continues lower in search of stronger support at a lower band.
4/8 Line (Major Support/Resistance)
• 4/8 provides the strongest support and resistance inside the Murrey frame.
• When price is above 4/8, this line acts as a powerful support.
• When price is below 4/8, it acts as dominant resistance.
• This is one of the best price areas to look for fresh long or short setups.
3/8 Line (Bottom of the Trading Range)
• If price is below 3/8 and moving upward, 3/8 initially acts as resistance and is usually not easy to break.
• Once price breaks above 3/8 and holds there for some time, it tends to stay above this line.
• In many cases, price will then spend roughly 40% of its time moving between 3/8 and 5/8, completing the core trading range.
1/8 Line and Extended Octaves
1/8 Line (Weak, Stop & Reverse Level)
• The 1/8 band offers only weak support.
• If price drops quickly into 1/8 and pauses there, a sharp bounce is possible.
• But if price doesn’t pause at 1/8, it can easily continue down to the ultimate 0/8 level.
Extended Murrey Octaves
Standard Murrey principles use these lines to mark clear support and resistance zones for trading strategies.
Some MML support/resistance indicators also include extended octaves: +1/8, +2/8 above the frame and −1/8, −2/8 below it.
When price breaks through these extended bands, the MML S&R indicator will typically “print” a new octave—reframing the range and recalculating all the Murrey levels.
Wrap-Up:
Murrey Math Lines convert the market’s harmonic structure into eight clear price bands.
8/8 and 0/8 define the ultimate extremes, 5/8–3/8 form the core trading range, 4/8 anchors major support/resistance, and 7/8, 6/8, 2/8, and 1/8 act as stall and reversal pivots.
By mapping trades to these levels—and watching how price behaves at each octave—traders can structure entries, stops, and profit targets around a systematic support and resistance framework.
