On Balance Volume relates volume to price change. It is calculated by adding the day's volume to a cumulative total when the security's price closes up, and subtracting the day's volume when the security's price closes down.

If today's close > yesterday's close then
OBV = yesterday's OBV + today's volume
If today's close < yesterday's close then
OBV = yesterday's OBV - today's volume
If today's close = yesterday's close then
OBV = yesterday's OBV
