DD Ratio

The DD Ratio (“Directional Distribution Ratio”) is a breadth indicator that shows, in real time, how many of the selected stocks (e.g., S&P 500 components) are bullish vs. bearish relative to today’s open.

The DD Ratio tells you what’s really happening under the hood of the index:

Futures may mislead: An index future (like ES or NQ) can rise on a few heavy-weighted stocks even while most components fall.
The DD Ratio exposes that divergence.

Breadth confirmation: When the futures are up and DD Ratio ≥ 0.5 → healthy rally.
When futures are up but DD Ratio < 0.5 → weak, narrow advance.

Intraday sentiment gauge: It updates live with each bar, reflecting “who’s winning” since the open.
