OBV

On Balance Volume

On Balance Volume (OBV) looks at volume flow. This chart study adds volume on 'up' days and subtracts volume on 'down' days. A period's volume is positive when the closing price level is above the previous close, and vice versa.

No parameters.

Indicators can be divergence of the OBV from the price level (indicating a possible change in the direction of the price level).

Also, in a market that is trending upwards (downwards), successively lower (higher) peaks of the OBV may indicate that the trend is due to end.

OBV can also be used to confirm price trends. This is when the OBV is moving in the same direction as the price level.
