LR Angle | julzALGO
LR Angle | julzALGO is a trend-angle visualization tool built around Linear Regression slope measurement.
Instead of judging trend strength only by how steep a line appears on the screen, the indicator calculates the slope mathematically, normalizes it with ATR, and converts it into a degree reading.
This provides a standardized way to evaluate trend direction and relative slope strength across different symbols, price levels, and volatility conditions.
The indicator is designed to answer one simple question:
Is the Linear Regression slope rising, falling, or becoming balanced?
Overview
LR Angle measures the angle of a Linear Regression line using market data rather than chart pixels.
The script compares the current Linear Regression value with its value a selected number of bars ago. It calculates the slope per bar, normalizes that slope using ATR, and converts the result into degrees using `math.atan()`.
This creates a digital-protractor-style angle reading:
Positive angle = rising Linear Regression slope
Negative angle = falling Linear Regression slope
Near zero = flatter or more balanced slope
The visual tools are designed to make this measurement easier to interpret directly on the chart.
Main Features
Linear Regression Angle Line
The indicator plots a Linear Regression line directly on the main chart.
The line color changes according to the calculated angle:
Green = rising slope
Red = falling slope
Neutral = flat or calculation not yet available
This provides a direct visual representation of the current trend-angle condition.
Default Linear Regression Length: 50
Visual Protractor
LR Angle includes an on-chart digital protractor-style display.
The protractor shows:
* Curved degree guide
* Tick marks
* Degree labels
* Directional needle
* Positive-angle orientation when the slope is rising
* Negative-angle orientation when the slope is falling
When the calculated angle is positive, the protractor represents the rising slope.
When the calculated angle is negative, the protractor flips downward to represent the falling slope.
The protractor is a visual representation only. The actual degree value is calculated mathematically from the ATR-normalized Linear Regression slope.
B / S Flip Labels
The script can display small B and S labels when the calculated angle state changes.
B : appears when the angle enters a rising condition
S : appears when the angle enters a falling condition
The optional B / S Angle Threshold allows users to require a minimum angle before a new state is recognized.
Example:
Threshold = 0° → any positive or negative state change can trigger
Threshold = 5°→ B requires an angle above +5°, while S requires an angle below −5°
These labels are directional angle-state markers. They are not automatic trade entries and can be combined with market structure, price action, volume analysis, and risk management.
Multi-Length Angle Matrix
The Angle Matrix compares multiple Linear Regression angle readings simultaneously.
Default rows:
LR 50
LR 100
LR 150
LR 200
Each row displays:
* Linear Regression length
* Calculated angle
* Direction state
* Strength blocks
Matrix states:
UP = angle is above the Balance Zone
DOWN = angle is below the negative Balance Zone
BALANCE = angle is inside the selected neutral range
The strength blocks fill according to the absolute angle relative to the selected Full Strength Angle
For example, if Full Strength Angle is set to 30°, readings approaching ±30° progressively fill more blocks. At or beyond the configured Full Strength Angle, the meter reaches full strength.
This makes it easier to compare weaker, balanced, and stronger directional slopes at a glance.
How the Angle Is Calculated
The calculation can be represented as:
Angle = atan(((LR − LR[N]) / N) / ATR) × 180 / π
Where:
LR = current Linear Regression value
LR[N] = Linear Regression value N bars ago
N = Slope Lookback
ATR = Average True Range used for normalization
atan = arctangent function
180 / π = conversion from radians to degrees
Step-by-Step Calculation
1. Calculate the current Linear Regression value.
2. Compare it with the Linear Regression value from N bars ago.
3. Divide the change by N to calculate slope per bar.
4. Divide the slope per bar by ATR to normalize it.
5. Apply `atan()` to the normalized slope.
6. Convert the result from radians into degrees.
Why ATR Normalization Is Used
Raw slope values are difficult to compare across markets.
For example, a 10-point movement in gold, BTC, forex, or a stock does not represent the same relative market movement.
ATR normalization scales the Linear Regression slope relative to the instrument's recent trading range.
This helps make the angle measurement more comparable across:
* Different symbols
* Different price levels
* Different volatility conditions
* Different chart environments
The result should still be interpreted in the context of the selected timeframe and settings.
Important Note About the Angle
The angle displayed by this indicator is **not the physical screen angle** of the plotted Linear Regression line.
Chart zoom, chart height, price scale, and screen dimensions can make any plotted line appear steeper or flatter.
LR Angle does not measure pixels or chart geometry.
Instead, it calculates a mathematical angle from the ATR-normalized Linear Regression slope, so the displayed degree reading is based on market data rather than the visual geometry of the chart.

How to Use
Rising Condition
When the Linear Regression line is green and the angle is positive, the calculated Linear Regression slope is rising.
If several Angle Matrix rows also display UP, multiple configured Linear Regression lengths are showing positive slopes.
Falling Condition
When the Linear Regression line is red and the angle is negative, the calculated Linear Regression slope is falling.
If several Angle Matrix rows also display DOWN, multiple configured Linear Regression lengths are showing negative slopes.
Balanced Conditions
When the angle is near zero, the measured slope is flatter.
The Balance Zone Angle determines how much positive or negative angle is classified as BALANCE in the matrix.
For example, with the Balance Zone set to 5°:
+3° = BALANCE
0° = BALANCE
−3° = BALANCE
Balanced readings indicate that the normalized Linear Regression slope is currently within the configured neutral range.
Reading the Matrix
The matrix helps compare shorter- and longer-length Linear Regression slopes.
Example of directional alignment:
LR 50 = UP
LR 100 = UP
LR 150 = UP
LR 200 = UP
This indicates positive slope readings across all four configured Linear Regression lengths.
Example of mixed conditions:
LR 50 = UP
LR 100 = BALANCE
LR 150 = DOWN
LR 200 = DOWN
This indicates disagreement between the shorter- and longer-length slope measurements.
Practical Uses
LR Angle can be used for:
* Trend-direction confirmation
* Relative slope-strength analysis
* Identifying flat or low-slope conditions
* Comparing shorter- and longer-length trend slopes
* Confirming pullback or continuation setups
* Filtering signals from another strategy
* Supporting discretionary market-structure analysis
It can also be combined with other forms of analysis such as price action, market structure, volume, support and resistance, VWAP, or order blocks.
Repainting / Real-Time Behavior
LR Angle does not intentionally reference future bars.
Values on historical bars are calculated from data available to those bars. On the current open candle, however, price, ATR, Linear Regression, angle readings, matrix values, and directional states can change as new price data arrives.
For traders who require confirmed readings, evaluate the indicator after the candle has closed.
Disclaimer
This indicator is intended for technical analysis and educational purposes only. It does not provide financial advice or guarantee future market direction or trading performance.
The B and S labels identify changes in the calculated angle state and should not be interpreted as guaranteed buy or sell signals.
Always use appropriate risk management and confirm trading decisions with your own analysis.

Rising Condition
When the Linear Regression line is green and the angle is positive, the calculated Linear Regression slope is rising.
If several Angle Matrix rows also display UP, multiple configured Linear Regression lengths are showing positive slopes.
Falling Condition
When the Linear Regression line is red and the angle is negative, the calculated Linear Regression slope is falling.

When the angle is near zero, the measured slope is flatter.
The Balance Zone Angle determines how much positive or negative angle is classified as BALANCE in the matrix.
For example, with the Balance Zone set to 5°:
+3° = BALANCE
0° = BALANCE
−3° = BALANCE
Balanced readings indicate that the normalized Linear Regression slope is currently within the configured neutral range.
