FTB-C000526 / Implementation concept

Equal-Close OBV Contribution

An equal close contributes zero to OBV even when volume is positive.

Definitions

In plain terms

No volume is added or subtracted when the current and prior closes match.

Technical

If C_t = C_(t-1), sign(C_t-C_(t-1)) = 0 and the contribution is exactly 0.

Scope

Equal-close volume is not evidence of a positive or negative OBV move.

Examples

  • A reviewer computes Equal-Close OBV Contribution from a small OHLCV fixture and checks readiness, units, and edge cases before publication.

Common misconceptions
