Zweig Breadth Thrust

Zweig Breadth Thrust Detector
This indicator tracks one of the rarest and most powerful bullish signals in market history: the Zweig Breadth Thrust.
It calculates the 10-day moving average of NYSE advancing stocks divided by the sum of advancing and declining stocks. When the breadth reading surges from deeply oversold (<0.40) to explosively bullish (>0.615) within just 10 trading days, it signals a momentum reset so intense that it often marks the start of major new bull runs.
Zweig Thrusts are extremely rare — but when they occur, historical odds favor significant market gains over the next 6 to 12 months.
This tool doesn't just chase price — it measures raw internal strength across the entire market.
When the masses panic, and the army of stocks surges together — that's when legends are made.
