# Volume Ratio

## Definition

The **Volume Ratio** measures the **relative dominance of buy volume versus sell volume** from executed market orders within a specific timeframe. It provides insight into **order flow imbalance** by comparing the net difference between buy and sell volumes against their combined total.

$$
\textbf{Volume Ratio} = \frac{\textbf{Buy Volume} - \textbf{Sell Volume}}{\textbf{Buy Volume} + \textbf{Sell Volume}}
$$

#### **Key Components:**

* **Buy Volume:** The total volume of market **buy orders** executed during the timeframe.
* **Sell Volume:** The total volume of market **sell orders** executed during the timeframe.
* **Ratio Range:** The ratio is typically **bounded between -1 and +1**, where:
  * **+1:** 100% buy volume dominance (only buy orders).
  * **-1:** 100% sell volume dominance (only sell orders).
  * **0:** Equal buy and sell volumes, indicating balance.
