The IGChartView™ control’s OnBalanceVolumeIndicator (OBV) calculates a running total of sales volume for a stock and displays whether this volume is flowing in (purchasing) or out (selling) of a given stock. The total volume for a day is given a positive or negative value depending on whether the prices were higher or lower that day than the previous day. A higher closing price would yield a positive value and a lower closing price would result in a negative value. These values are accumulated into the running total.
