NinjaScript > Language Reference > Common > Attributes

Definition

Determines the sequence in which a NinjaScript object's Display.GroupName categories are arranged in relation to other categories in the UI. The default behavior will display each GroupName of an object in alphabetical order, however this behavior can be changed by defining the CategoryOrder attribute before the object's declaration.

Notes:

•The CategoryOrder attribute is ONLY valid on class-level declarations.

•Categories with values less than 1,000,000 appear at the very top of the property grid (excluding the Strategy Analyzer "General" category)

•NinjaTrader UI reserves using values ending in 000, 500 and the values documented below are subject to change

•If you wish to inject your category between a standard NinjaScript category, please refer to the table below to locate the appropriate position (e.g., to set a property after "Data Series" and before the "Setup" use value of 2,000,001)
