Breadth Thermometer
How many of the QQQ's big names are actually rising? The index can lie; breadth doesn't.

What it shows
- One line: the percentage of the QQQ's 38 largest holdings trading with RSI(14) above 50.
- Zones: under 20% (fear), under 10% (capitulation), over 80% (overheated).
- Alerts when the line enters each zone.
How it reads the market
An index at highs with thin participation is fragile; an index at lows with breadth already washed out is late in the decline. Watching the share of leaders above the RSI midline gives you that participation read in one line.
Settings
| Setting | Default | What it does |
|---|---|---|
| RSI length | 14 | The per-name momentum measure. |
| Midline | 50 | A name counts as rising when its RSI is above this. |
| Zone thresholds | 20 / 10 / 80 | Where fear, capitulation and overheated start. |
Everything is an input: colors, thresholds and time windows adjust from the indicator's settings panel, no code needed.
