Application configuration

You can change FX Mobile’s main configuration settings by editing the file /public/<version>/AppConfig.json, located within FX Mobile’s WAR file.

For blotter configuration settings, see Blotter Configuration.

Editing the configuration file

The path to the configuration file within the WAR file is /public/version/AppConfig.json. For guidance on how to edit AppConfig.json, see How can I configure FX Mobile.

Configuration file format

The configuration file, AppConfig.json, contains a single JSON object, with each configuration item a property of the object.

All property names and enumerated values are case sensitive unless stated otherwise.

Many properties with numeric values are written as JSON strings. This is a deliberate decision to avoid issues that may arise from floating-point rounding error.

The table below lists the properties of the configuration object.
