Market quality codes

Each market stamps quality on the wire in its own vocabulary. The API maps each market’s quality level to a shared ladder per the table below.

How the volume was arrived at, in ascending order of trust. When one settlement period carries several records, prefer the highest quality.

Available allocation qualities

  • provisional — A placeholder the sender intends to replace.

  • estimated — Substituted because no reading was available: profiled, interpolated, or copied from a comparable period. Expect it to be superseded.

  • calculated — Derived by a defined computation rather than read

  • measured — Read off the meter.

Available options:
provisional,
estimated,
calculated,
measured
Example:
