The On Balance Volume (OBV) is a cumulative volume-based indicator that adds volume on up days and subtracts it on down days. A rising OBV confirms an uptrend with strong buying interest, while a falling OBV warns of distribution — making it a powerful tool for validating price movements with volume flow.
This sample displays MSFT daily OHLC prices on the first plot, an OBV indicator with a blue (#55f) stroke on a 25% height second plot, and a Volume plus Moving Average indicator on a 20% height third plot. Y-axis labels on both indicator plots use abbreviated formatting for large numbers. The chart includes a column scroller driven by volume data, a range picker, and a range selector, with the default view showing year-to-date data.
