Moving Average (Simple exponential to use current day)

Hello,

I’m new to the forum and Knime and need a little bit of direction.

I have two columns, date (String) and close (D), and want to take the simple exponential moving average of the close value. I’m unable to calculate the current/latest day’s moving average (it just shows as the close value). Is this how the node works? how would I be able to calculate the moving average of the current/latest moving average?

Appreciate the help!
