# Create Real Time Segment Rules

After creating a segment, you can create rule sets to refine the segment, including drag-on rules (Drag-on rules must be enabled in the parent segment). Individual rules are categorized by Attributes, Behaviors, Existing Segments, and Predictive Scores. Unlike batch segments, you are not able to access Funnels and A/B Testing. Additionally, you cannot create activations from a real-time segment.

| Rule Type | Description |
|  --- | --- |
| Attributes | Predefined characteristics of the customer such as age, email, gender, etc. |
| Behaviors | Real-time behaviors of the customer such as page views |
| Existing Segments | A predefined rule set used for another real-time segment |
| Predictive Scores | A predefined rule set for predictive scoring models. |


## Creating Rules

Real-time segments do not have all of the operators and aggregate types available in batch segments.
The following are not available:

* Operators- IsNull, Regexp, EndWith, TimeRange
* Aggregation type- CountDistinct, Average
* Calculation (min, max, sum) and Order (first, last) don't support grouping columns or order by columns


1. Add additional rules (up to 26) and apply one or multiple rules using all or any match logic.

You can only select real-time behaviors coming from the JS SDK and must set up a Profiles API Token to track those in your real-time segment.You must set the Time frame "within" value to greater than zero.

1. After finishing setting up your rules, select Save.
2. Next, set up your [Profiles API Token](/products/customer-data-platform/audience-studio/profiles/create-a-profiles-api-token).
