RBI Policies

An RBI Policy allows you to develop and execute strategies based on historical data and dynamic data, which is obtained by monitoring conditions in real time. The policies used in RBI are categorized as follows:

These policies appear in the Module Workflow Policies section of the Policy Designer Overview page.
