Frequently Asked Questions

ta.obv is On Balance Volume: running sum of volume signed by whether close rose or fell vs the previous close, giving a cumulative view of volume-weighted direction.

Rising OBV with rising price supports the trend. If price makes new highs but OBV does not (bearish divergence), some traders expect weakening buying pressure.

Divergence is when price and OBV disagree—for example price up but OBV flat or down. It can warn that the move lacks volume confirmation, but it is not a timing signal by itself.
