When creating out-of-the-ordinary transaction patterns in Tool #101 Abnormal Activity Monitoring, how is the average daily transaction amount calculated?

As of the 24.10 Release, you can configure the system to calculate the average daily transaction amount based on either the number of days in the period or the number of transactions in the period.

For example, let’s say we set a 30-day period, and a member submits RDC checks for $300, $400, and $500 every month, adding up to a total of $1200 worth of RDC transactions per period. Using the # of days calculation option, the system would divide the $1200 total by 30 days (the configured period) to find the average daily transaction amount, which would be $40, in this case. So, when the member deposits their $300 RDC check, it would be flagged as being 750% higher than the average daily transaction amount (i.e., $40).

With the # of transactions calculation option, the system calculates the average based on the number of transactions within the period, providing a more accurate average transaction amount. In this example, the $1200 total would be divided by 3 (since there were 3 RDC transactions within the period), resulting in an average of $400. So, when the member deposits their $500 RDC check, it would be only 125% higher than the average (i.e., $400), which should not be flagged as abnormal activity.
