The article says the 10-day window helps place buy signals near bear market bottoms or deep correction lows. A Zweig thrust occurs when the breadth ratio first drops below 0.40 and then rises above 0.615 within 10 days.

The Zweig breadth thrust is based on the ratio of advancing issues to total issues, commonly using NYSE data. The Zweig breadth thrust was popularized by Martin Zweig.
