Open Marketplace floor rules
This article describes the optional open marketplace inventory rules.
By default, all of your inventory is programmatically available to buyers within the open marketplace (accordingly to your enabled Third-party Processors (demand partners), unless you use the Open Marketplace Inventory Rules to place limits on that inventory.
Open Marketplace inventory rules are based on inclusion, using the same targeting criteria as described above, for creating Global Inventory Exclusion Rules. However, in this case you are creating inclusion rules for the open marketplace.
As with all inclusion rules, when you select something to be included, all other items from the same category are excluded. For example, if you include a country (in Geographical targeting), all other countries are excluded. Similarly if you include only pre-rolls (in Content/Position targeting) the other options in that category (mid-rolls and post-rolls) are excluded.
If you do not explicitly include any items from a targeting category, then all items from that category are included. For example, if you do not include any specific countries (in Geographic) then all countries are included.

Tips for Creating Open Marketplace Inventory Rules
Only inventory matching one of the rules will be offered for sale in the Open Marketplace. However, if no rules are provided, all inventory is offered.
Each rule is evaluated independently of the others.
Items within a rule operate on an AND basis (for example, include Canada AND mid-rolls). The behaviour between rules operates on an OR basis (for example, include Canada OR include mid-rolls).
Best practice is to create a single rule (using AND logic), because separate rules are evaluated independently (using OR logic), and therefore the rule enforcement can become quite complicated and you might not always get what you expect. (See example, below.)
Rule Example
You only want to exclude Canada from all open marketplace inventory and you only want to expose mid-roll and post-roll inventory elsewhere.
Option 1 (success):
Create a single rule that includes mid-rolls and post-rolls AND excludes Canada.
Result:
Success: Listeners in Canada are excluded from the open marketplace.
Success: Listeners outside of Canada are only included for mid-rolls and post-rolls.
Option 2 (fail):
Create a rule that excludes Canada.
Create another rule that includes mid-rolls and post-rolls.
Result:
Success: Listeners in Canada are excluded.
Success: Mid-rolls and post-rolls are included.
Fail: Listeners outside of Canada are included for pre-rolls because they match the first rule, and the OR logic essentially ignores the second rule because it is evaluated separately.
