Volume weighted by how much price moved, added up.
Like OBV, but each candle counts in proportion to its percentage move instead of only its direction.
Worked out by the same code the builder uses, on stored daily candles. Move a setting and the line moves with it. This is what happened, not what will happen.
Gate: Price volume trend is rising.
A cumulative line depends on where you started counting. Its level means nothing; only its direction does.
