Volume Price Trend (VPT): Definition and Formula

Definitions

Unlike OBV, it uses the size of the close-to-close return, not only its sign.

VPT_t = VPT_(t-1) + V_t × (C_t-C_(t-1))/C_(t-1), with a zero seed and strictly positive closes.

Comparisons require a consistent price-adjustment basis and volume definition.

VPT_t = VPT_(t-1) + V_t (C_t-C_(t-1))/C_(t-1)

LaTeX: VPT_t = VPT_{t-1} + V_t \frac{C_t-C_{t-1}}{C_{t-1}}

Symbol	Meaning	Unit
`C_t`	current close	price
`V_t`	current volume	volume

Output unit: volume units
