On−Balance Volume

The on−balance volume (OBV) indicator was created to try to uncover accumulation and distribution patterns

of large player in the stock market. This is a cumulative sum of volume data, specified as follows:

If today’s close is greater than yesterday’s close

OBV

t

 = OBV

t−1

 + 1

If today’s close is less than yesterday’s close

OBV

t

 = OBV

t−1

 − 1

The absolute value of the index is not important; attention is given only to the direction and trend.
