Volume in rising Nasdaq stocks against volume in falling ones: where the money is going.
Latest reading, Friday, November 13, 2026Even: −1.19
Its job in a momentum trade
It shows whether the volume is behind the move. It is usually the slowest of the confirmations, so it backs a trade more often than it starts one.
What it measures
The advance-decline ratio counts stocks. This one weighs them by trading volume, so it shows whether the day's volume is going into rising Nasdaq stocks or falling ones.
How it is computed
- When up volume leads, the reading is up volume divided by down volume.
- When down volume leads, the reading is minus (down volume divided by up volume).
- So +2 means twice as much volume in rising stocks, −2 means twice as much in falling stocks, and the scale has no ceiling. Both +1 and −1 mean an even split, and no reading falls between them.
How to read it
- Beyond ±2 the volume is clearly on one side. Beyond ±4 it is a heavily one-sided day.
- A reading that keeps growing through the session means the dominant side is still adding.
- A reading that shrinks toward ±1 while the price holds its trend says the move is losing its volume.
How to trade it
- Read it next to the advance-decline ratio. When both are one-sided in the same direction, the move has both the stocks and the volume behind it.
- When they disagree, for example most stocks up but volume even, the move is less trustworthy.
- A flip of sign during the session is rare and worth noting. It means the volume changed sides.
What it cannot tell you
- Early in the session a small amount of volume can produce a large ratio.
- These reads are how the indicator is commonly used. They have not been tested here as trading rules.
