Zweig Breadth Thrust – NYSE Original – Modern Version using AD% – Current Situation

This indicator sets up with when the advance-decline data becomes oversold and triggers when there is a sharp broadening in upside participation (advancing stocks). It is a time sensitive indicator that must trigger within a 10 day window.
