There are three types of alerts supported by Optuma, starting with a basic price trigger (when a symbol crosses above or below a specified price). The second is time alerts that can be based off cycle analysis, or just a reminder of an upcoming event such as an interest rates decision. The third type is the Technical Analysis alert—powered by scripted criteria, alerts can trigger based off Moving Average crossovers, indicator values, changes in direction, etc.

This video gives you a brief overview of the alerts system, and how each type of alert can be set up in Optuma.
