FTB-C000536 / Implementation concept

ADL Zero-Range Policy

ADL zero-range policy defines the multiplier when high equals low.

Definitions

In plain terms

When a bar has no range, the contract assigns no close-location contribution rather than dividing by zero.

Technical

For H_t = L_t, MFM_t = 0 and therefore MFV_t = 0; the ADL level remains unchanged for that bar.

Scope

Replacing the zero-range policy with a missing value changes readiness and downstream results.

Examples

  • A reviewer computes ADL Zero-Range Policy from a small OHLCV fixture and checks readiness, units, and edge cases before publication.

Common misconceptions

  • Replacing the zero-range policy with a missing value changes readiness and downstream results.
