Intermediate 1 linked topicEvidence-reviewed

Definitions

In plain terms

A level carries the entire prior path, so later values depend on earlier updates.

Technical

OBV_t is initialized at zero and equals the prior level plus the current signed-volume increment.

Scope

The absolute level depends on the chosen seed and is not comparable across arbitrary seeds.

Examples

  • A reviewer computes OBV Cumulative Level from a small OHLCV fixture and checks readiness, units, and edge cases before publication.

Common misconceptions

  • The absolute level depends on the chosen seed and is not comparable across arbitrary seeds.
