FTB-C000538 / Implementation concept

ADL Initial Seed

ADL initial seed is the starting cumulative level before the first bar contribution.

Definitions

In plain terms

A zero seed makes the first reported level reproducible and easy to audit.

Technical

The Batch 010 contract sets ADL_0 = 0 and applies the first bar's MFV at index 0.

Scope

Changing the seed shifts the level without changing per-bar MFV values.

Examples

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

Common misconceptions

  • Changing the seed shifts the level without changing per-bar MFV values.
