### Volume Bar Range Ratio

This study calculates and displays the Volume Bar Range Ratio for the Price and Volume Data.

Let $$H_t$$, $$L_t$$, and $$V_t$$ be the High Price, Low Price, and Volume, respectively, at Index $$t$$.

The Volume Bar Range Ratio at Index $$t$$ is denoted as $$VBRR_t$$, and it is computed for $$t \geq 0$$ as follows.

$$\displaystyle{VBRR_t = \left\{ \begin{matrix} \frac{V_t}{H_t - L_t} & H_t - L_t > 0 \\ VBRR_{t - 1} & H_t - L_t \leq 0 \end{matrix}\right .}$$
