D-009 Which codes may pricetype take beyond 0 to 3, when the text says "Exchange-specific auction types can be defined using values 500 and greater"?

What the schemas do

Any integer of 500 or more, an exchange's own auction type, beside the codes 0 to 3; no code from 4 to 499.

Options

• vendor-500 Chosen

  Any integer of 500 or more, an exchange's own auction type, beside the codes 0 to 3; no code from 4 to 499.

• closed

  Only 0 to 3: the sentence permits exchanges to define more but doesn't add them to the list.

Why

The sentence reserves 500 and up for exchanges' own auction types, as AdCOM's lists reserve 500 and up for vendors, so a receiver must accept such a code and may not know it. Codes from 4 to 499 stay unassigned.

What we ask the specification to state

None needed: the range is clear. A list of the codes exchanges use would help a receiver read them.

The specification lines it rests on

Each line is quoted as the record pins it. Expand an item to read the quote.
