Here, the average risk level over all account holders is calculated. Replace the operator
AVG with, for example,
MAX if you are looking for the highest risk level for an account holder. Replace the parameter
aum if you want to know the average value of assets under management for your account holders. Don't forget the single quotation marks around the parameter.
You can also use the operator
get_properties_from_instances in a boolean expression, if, for example, you want to trigger something when the average overall risk level raises above 3.
Simply add the comparison, e.g.
> 3 at the end:
AVG(get_properties(instances(AccountHolder), 'risk_level')) > 3
