Put a chart in context
Combine price levels, indicators and market breadth. Explore charts without turning a historical pattern into a trading promise.
A practical research workflow
- Choose a time frame and identify the price levels that matter for your question.
- Use indicators to describe price behavior, then check participation across the wider market. Correlated indicators are not independent confirmations.
- Save the instrument and set a price alert so you can revisit the setup without watching every tick.

Relative strength and market breadth: ratio lines, A/D and % above MA
How to measure a stock or sector against a benchmark with a ratio line, how breadth gauges like the advance/decline line work, and what they showed in 2025–2026.
