Relative Strength Suite [BLC]📊 Relative Strength Suite
A powerful, all-in-one relative strength toolkit for traders and analysts. Whether you're a trend follower, momentum trader, or sector rotator, this script gives you the flexibility to analyze and screen assets using three distinct RS methodologies—all in one clean interface.
🔍 What It Does
Flexible Relative Strength allows you to compare any asset to a benchmark (like SP:SPX , NASDAQ:QQQ , AMEX:IWM , etc.) using one of four modes:
📈 Relative Strength – Classic price ratio comparison
📘 Dorsey Relative Strength – Smoothed trend-based RS using EMA
📒 Mansfield Relative Strength – Momentum-based RS normalized to its own average
🧮 Screener Mode – Load Indicator into Pine Screener to see all 3 values.
🛠️ Key Features & Settings
🧩 Relative Strength
Comparison Symbol: Select the ticker you want to use as a benchmark.
Highlights new highs/lows in Relative Strength with dynamic line coloring:
🟢 Green = New high (outperformance)
🔴 Red = New low (underperformance)
Optional moving average overlay (SMA, EMA, WMA, HMA) for trend smoothing.
✅ Use Case: Identify when a stock is gaining strength relative to the market or sector.
📘 2. Dorsey RS (Smoothed Trend)
Uses an EMA of the RS ratio to smooth out noise.
Rising Dorsey RS = consistent outperformance.
Falling Dorsey RS = consistent underperformance.
✅ Use Case: Spot long-term relative trends regardless of price volatility.
📒 3. Mansfield RS (Performance Momentum)
Compares RS ratio to its own long-term SMA (default 200).
Values above 0 = outperforming the benchmark.
Values below 0 = underperforming.
✅ Use Case: Ideal for momentum traders and Stan Weinstein-style stage analysis.
🧮 4. Screener Mode
Not for use on your chart. This is only to use in TradingView's Pine Screener.
Displays all three RS lines simultaneously.
Includes all 3 modes to act as screener signals
🛠️How to Use Screener Mode
Add this indicator to your favorites list.
Open Pine Screener and select this indicator.
Select your timeframe.
Click Settings & Change Strength Type to Screener > Click Apply
Hit Scan!
New High Low Signal: Finds stocks making a new RS high (1) or low (-1) over your lookback period.
Dorsey Trend Signal: Finds stocks where the smoothed RS trend is rising (1) or falling (-1).
Mansfield Zone Signal: Finds stocks where momentum is in the positive zone (1) or negative zone (-1)
✅ Use Case: Quickly scan multiple assets for relative strength breakouts, trend shifts, or momentum zones.
🧪 Pro Tip
Combine this indicator with volume, price structure, or moving averages to confirm breakouts and trend strength. Use Screener Mode on a watchlist to identify top RS candidates in seconds.
To clean up your screener table, click the column settings icon ( ⋮ ) and uncheck any columns you don't need to see. You can still filter by them even if they are hidden.
📝 Credits & Notes
Inspired by classic RS methods (including Dorsey and Mansfield).

Dorsey
Dorsey InertiaThis indicator was originally developed by Donald Dorsey (Stocks & Commodities, V.13:9 (September, 1995): "Refining the Relative Volatility Index").
Inertia is based on Relative Volatility Index (RVI) smoothed using linear regression.
In physics, inertia is the tendency of an object to resist to acceleration. Dorsey chose this name because he believes that trend and inertia are related and that it takes more effort and energy to reverse the direction of a stock or market than to keep it in the same direction. He argues that the volatility is the simplest and most accurate measure of inertia.
When the indicator is below 50, it signals bearish market sentiment and when the indicator is above 50 it signals a bullish trend.
Good luck!
Mass IndexThis indicator was originally developed by Donald Dorsey (Stocks & Commodities, V.10:6 (June, 1992): "The Mass Index").
Specially for @AlexMayorov :
If indicator reaches 27 and then falls to below 26.5 then it could be a signal of potential trend reversal.
Relative Volatility IndexCorrected Relative Volatility Index. This indicator was originally developed by Donald Dorsey (Stocks & Commodities V.11:6 (253-256): The Relative Volatility Index).
The indicator was revised by Dorsey in 1995 (Stocks & Commodities V.13:09 (388-391): Refining the Relative Volatility Index).
I suggest the refined RVI with optional settings. If you disabled Wilder's Smoothing and Refined RVI you will get the original version of RVI (1993, as built-in).
Also, you can choose an algorithm for calculating Standard Deviation.
MASS Index Backtest The Mass Index was designed to identify trend reversals by measuring
the narrowing and widening of the range between the high and low prices.
As this range widens, the Mass Index increases; as the range narrows
the Mass Index decreases.
The Mass Index was developed by Donald Dorsey.
