On-Balance Volume (OBV) is a momentum-based technical indicator developed by Joseph Granville in 1963. It is designed to measure the cumulative flow of volume to predict changes in asset price, based on the theory that volume precedes price movement. The calculation is straightforward: if the current closing price is higher than the previous close, the period's volume is added to the running total; if the close is lower, the volume is subtracted; if the price is unchanged, the OBV remains the same. Analysts use OBV primarily to confirm existing trends or identify potential reversals through divergences. When both price and OBV are making higher highs, the uptrend is considered healthy and likely to continue. Conversely, if price rises while OBV falls or plateaus, it suggests 'smart money' is exiting, signaling a weak trend. OBV has no default lookback parameters as it is a cumulative running total, though many traders overlay a 20-period Moving Average to identify trend shifts. It is most effective when used alongside price action and oscillators to filter out noise in non-trending markets.
Signal Types
Trend Confirmation
When OBV moves in the same direction as price, it confirms the strength of the current trend.
Bullish Divergence
Occurs when price makes a lower low but OBV makes a higher low, suggesting an upward reversal.
Bearish Divergence
Occurs when price makes a higher high but OBV makes a lower high, suggesting a downward reversal.
OBV Breakout
When the OBV line breaks above a previous resistance level, it often precedes a price breakout.

FAQ
Does the absolute value of OBV matter?
No, the actual numerical value of OBV is irrelevant. Traders should focus on the direction, slope, and relationship of the OBV line relative to price.
What are the limitations of OBV?
OBV can be distorted by massive volume spikes on a single day (e.g., earnings or block trades) that may not represent a long-term trend change.
Is OBV a leading or lagging indicator?
OBV is considered a leading indicator because volume often increases or decreases before price makes a significant move.
