What is the Advance-Decline Line (ADL)?

The ADL is a cumulative indicator that tracks the running total of Net Advancers (advancing stocks minus declining stocks) to show market breadth trends.

How do I detect market divergence?

You can use the `get_summation_and_divergence` tool. It compares the price index history against the ADL history to identify bullish or bearish divergence signals.

Can I calculate the McClellan Oscillator?

Yes, the `get_oscillator_metrics` tool calculates both the AD Line Oscillator and the McClellan Oscillator using historical Net Advancer data.

This MCP server provides deterministic tools for calculating critical market breadth indicators. Use get_daily_breadth_metrics to compute Net Advancers and the cumulative Advance-Decline Line (ADL). Use get_oscillator_metrics to derive the AD Line Oscillator and the McClellan Oscillator from historical data. Finally, use get_summation_and_divergence to track the long-term Summation Index and detect bullish or bearish divergences between price indices and the ADL.
