Relative Strength Line
Measures how the chart symbol performs relative to a benchmark (SPY, QQQ, or any symbol) rather than in absolute terms — the dimension institutions actually trade: they buy what is stronger than the market. The indicator plots the classic RS line (price ÷ benchmark) or the normalized Mansfield RS oscillator, and turns it into an actionable confluence signal.
TradingView: (unpublished)
Designed for momentum equities (Tesla, Cloudflare, Microsoft, Apple, …) where relative strength vs. the index is the primary stock-selection filter.
The key idea: confluence, not raw RS
Relative strength alone is decoupled from price — a stock can be relatively strong (falling less than the market) while its own chart falls. A signal on raw RS would then say “long” while price drops, which is useless. So a signal here fires only when both agree:
- LONG — the stock outperforms the benchmark (Mansfield > 0) and is in its own uptrend (price above its trend EMA)
- SHORT — it underperforms and is in its own downtrend
That makes a green mark a genuine leader that is also rising, and structurally rules out the “green while price falls” contradiction.
Features
- Two display modes (one pane, no scale conflict):
- Mansfield RS (default) — normalized oscillator around zero: the % distance of the RS line from its own moving average. Above 0 = outperforming the benchmark, below 0 = lagging.
- Raw RS Line — the price ÷ benchmark ratio itself, with its moving average.
- Confluence markers — green up-triangle below the line on a long setup, red down-triangle above on a short (standard trading convention). Fires on entry into the regime, throttled by a minimum bar gap.
- Dashboard — relative strength (leads/lags + Mansfield %), absolute price trend, and the Setup verdict (LONG / SHORT / Neutral)
- Right-edge tag with the live setup
- Alerts — long/short confluence, Mansfield zero-cross up/down
How to read it
- Setup = LONG → the stock beats the market and is trending up — a momentum-leader long candidate.
- Mansfield > 0 but Price Trend = Down → relatively strong but absolutely falling → no signal (this is the case that used to mislead). It tells you the stock is holding up better than the index, but it is not a long.
- Mansfield crossing below 0 → the stock has started lagging the benchmark; rotate attention elsewhere even if price still rises.
Benchmark choice
AMEX:SPY(default) — broad market, S&P 500. The IBD standard.NASDAQ:QQQ— Nasdaq 100; usually the better reference for tech/momentum names.- Any symbol works (e.g. a sector ETF) via the symbol picker.
Settings
| Group | Input | Default | Purpose |
|---|---|---|---|
| Relative Strength | Benchmark | AMEX:SPY | Symbol to measure against |
| Relative Strength | Display | Mansfield RS | Oscillator vs. raw ratio |
| Relative Strength | Mansfield MA Length | 50 | MA the RS distance is measured from |
| Confluence Signal | Price Trend EMA | 50 | EMA of the stock’s price defining its absolute trend (the long/short filter) |
| Confluence Signal | Min Bars Between Markers | 5 | De-clutter repeated markers |
| Confluence Signal | Marker Distance from Line | 0.4 | Vertical gap of the marker from the line (× stdev) |
Notes
- The RS line uses
request.securitywithlookahead_off— no repainting beyond the standard same-timeframe behavior. - On a symbol where the benchmark has no data for the timeframe, RS is
naand the dashboard shows “—”.
