FTB-C000525 / Implementation concept

OBV Initial Seed

OBV initial seed is the declared starting level before any directional update.

Definitions

In plain terms

Using zero makes the first row a reproducible anchor rather than inventing a prior close.

Technical

The Batch 010 contract sets OBV_0 = 0; the first directional update is index 1.

Scope

Changing the seed translates the entire level but does not change later increments.

Examples

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

Common misconceptions

  • Changing the seed translates the entire level but does not change later increments.
