On-Balance , or OBV is considered a "leading indicator" - in contrast to a "lagging indicator" just as Moving Averages it does not show a confirmation what already happened, but it shows what can happen in the future. For example: The chart is climbing while the OBV oscillator is slowly declining, gets weaker and weaker, maybe even prints divergences? That means that a reversal might be occurring soon. Leading indicators are best paired with Stop and Resistance Lines, general , Fib Retracements etc...Your chart is approaching a very important Resistance Trendline but the OBV shows a very positive signal? That means there is a high probability that the Resistance is going to be pushed though and becomes Support in the future.
