Black Tie Murrey Math MTFMurrey Math grid implementation. Computes a price-octave grid divided into 1/8 levels within a "trading frame" sized to the recent price range. The grid auto-anchors to mathematically clean reference numbers based on the price's order of magnitude.
LEVELS
8/8 Top of frame, major resistance
7/8 6/8 Weak resistance and momentum levels
5/8 Top of fair-value zone, sell-bias area
4/8 Frame midpoint, magnet level in ranging markets
3/8 Bottom of fair-value zone, buy-bias area
2/8 1/8 Weak support and momentum levels
0/8 Bottom of frame, major support
+/- 1/8 to 3/8 Frame overshoots, statistical reversal zones outside the main frame
ALGORITHM
The frame is built in five steps. First, the indicator picks a "scale reference": a clean round number based on the price's order of magnitude. Second, it computes how many times to divide that scale by 8 to arrive at a unit comparable to the current range. Third, it derives a power-of-2 multiplier so the frame width matches the actual range. Fourth, it anchors the frame to the price midpoint by rounding to the nearest multiple of the half-frame. Fifth, if the actual range overshoots the computed frame by more than 25 percent, it retries with adjusted parameters.
This produces a stable grid that doesn't repaint on small price moves but adapts cleanly when price breaks into a new octave.
USAGE
Use 8/8 and 0/8 as primary range boundaries.
Use 5/8, 4/8, and 3/8 as fair-value reference points.
Use the extreme levels (+/- 3/8) as exhaustion zones for mean reversion setups.
SETTINGS
Calculation Timeframe lets you compute the grid on a higher timeframe and project it onto your execution chart.
Lookback Bars controls how much history is scanned. Default 64 is balanced; lower values adapt faster, higher values produce more stable grids.
Use Candle Bodies filters wicks out of the range calculation, which produces cleaner levels on noisy instruments.
Each of the 15 levels has individual visibility, color, and style controls.
