🔷 Trend Lines Premium Engine
Multi-Layer Market Structure & Dynamic Regression Indicator
https://chartshots.spotware.com/c/69d3c949a2e08
📌 What is it?
Trend Lines Premium Engine is an overlay indicator that combines 5 independent modules into a single tool. Each module can be toggled on or off. It maps market structure, dynamic channels, and volume-based regression zones directly on the price chart.
It answers three core questions:
- Where is price within the current structure?
- What is the dominant trend and where are the breaking points?
- At which price levels is activity concentrated?
🧩 The 5 Modules
1️⃣ Swing Range Connector
https://chartshots.spotware.com/c/69d3cab9b805b
Detects the most recent swing highs and swing lows, then draws a sloped channel connecting the oldest to the newest on both sides. The area between is filled as a dynamic range zone.
How it works:
- A bar qualifies as a swing point when its high (or low) is the most extreme compared to N bars before and N bars after it.
- A straight line is drawn from the oldest stored swing to the most recent, creating upper and lower boundaries.
- The channel shifts automatically each time a new swing point is confirmed.
How to read it:
- Price inside the channel → defined structural range.
- Break above/below → volatility expansion or structure shift.
- Channel slope → predominant range direction.
Parameter
Purpose
Bars Before / After Swing
Bars required on each side to confirm a swing. Higher = more significant swings
Max Swing Points
How many swings to store. Controls channel depth
History Window
How far back the channel is drawn
2️⃣ Segment Linear Channel
https://chartshots.spotware.com/c/69d3cb221bba1
Splits the analysis window into 5 equal segments, finds the highest high and lowest low in each, then fits a least-squares regression line through those 5 upper points and another through the 5 lower points.
How it works:
- The window is divided into 5 parts. One representative extreme is extracted per part.
- Linear regression is applied over those 5 points for each boundary.
- The result is a channel that adapts to segmented price structure rather than just two endpoints.
How to read it:
- Ascending channel → structural uptrend.
- Descending channel → structural downtrend.
- Repeated touches on a boundary → dynamic support/resistance.
Difference from Module 1: Swing Range connects only the first and last swing. Segment Channel uses 5-point regression, making it smoother and less reactive to a single swing.
3️⃣ Swing Point Labels
Detects swing highs and lows and classifies them into 4 market structure categories:
Label
Meaning
Indicates
HL
Higher Low
Bullish structure
HH
Higher High
Bullish structure
LH
Lower High
Bearish structure
LL
Lower Low
Bearish structure
How it works:
- Each new swing low is compared to the previous swing low. Higher → HL. Lower → LL.
- Each new swing high is compared to the previous swing high. Higher → HH. Lower → LH.
How to read it:
- HL + HH sequence → uptrend intact.
- LH + LL sequence → downtrend intact.
- An HL breaking into LL, or an LH breaking into HH → structure shift (BOS/CHoCH).
By default only HL and LH are displayed to keep the chart clean. HH and LL can be enabled for full structure visibility.
4️⃣ Automatic Trend Lines
https://chartshots.spotware.com/c/69d3cc071272e
Draws trend lines connecting the two most recent swing lows (bullish line) and the two most recent swing highs (bearish line). The active line is prominent; previous lines fade out.
How it works:
- New swing low detected → line drawn from prior swing low to the new one (bullish trend line).
- New swing high detected → line drawn from prior swing high to the new one (bearish trend line).
- The line projects forward by a configurable number of bars.
- When a new line is created, the previous one fades to a semi-transparent color.
Breakout signals (optional): When enabled, the indicator detects if the closing price crosses an active trend line:
- 🔼 Up arrow → bullish breakout.
- 🔽 Down arrow → bearish breakout.
Parameter
Purpose
Max Line Pairs
How many line pairs to keep visible. Set to 1 for cleanest view
Max Extension Bars
How far the line projects forward. Prevents lines from crossing the entire chart
5️⃣ Dynamic Regression Zone
The most advanced module. Calculates a linear regression channel on closing prices and overlays an activity profile (histogram) showing where volume or touches concentrated within the channel. It also marks key levels at the highest-activity zones.
A) Regression Channel:
- Least-squares linear regression is applied to closing prices over a given period.
- Standard deviation of prices from the regression line is calculated.
- Upper and lower bands are placed at N standard deviations from the center (default: 2.0).
- Optionally computed in logarithmic scale for better accuracy on high-price or high-volatility instruments.
B) Auto Period Detection:
- The algorithm tests multiple periods (50 to 400 bars) and calculates the Pearson correlation coefficient for each.
- It selects the period with the highest correlation — where the linear regression best fits the price movement.
- The correlation value is displayed on the chart (e.g., R = 0.85).
C) Activity Histogram:
- The channel is divided into horizontal sections (up to 25).
- For each section, the algorithm counts how many bars touched that price level, weighted by volume or number of touches (configurable).
- Higher-activity sections appear as longer, more opaque bars.
- This reveals the Point of Control (POC) and high/low activity zones within the channel.
D) Key Levels:
- The sections with the highest activity are projected forward as horizontal lines.
- They function as volume-based support and resistance within the regression context.
How to read it:
- Price near upper band → statistically overbought zone.
- Price near lower band → statistically oversold zone.
- R close to 1 or -1 → strong, reliable linear trend. R close to 0 → ranging or regression is not significant.
- Key levels act as price magnets — zones with historical activity concentration tend to attract price back.
