About the On Balance Volume Indicator
The On Balance Volume Indicator, commonly known as OBV, is a classic volume-based trading tool available for MetaTrader 4.
It focuses on measuring buying and selling pressure by analyzing how volume flows in relation to price movement.
The indicator is displayed in a separate sub-window below the main chart as a continuous oscillator line.
When volume increases alongside rising prices, the OBV line moves higher, reflecting bullish participation.
When volume expands during falling prices, the line declines, signaling bearish pressure.
The OBV indicator can be used in several ways.
Traders often rely on it for trade entries and exits, while others use it as a confirmation tool to validate trend direction.
It performs particularly well during active market periods such as the London and New York sessions, where volume plays a stronger role in price movement.
