Script to Manually Modifiable stop and target from Strategies Executed

Hi,
So far, NT customer support can not provde a screenshot of how this works and where to adjust the script and or code in existing strategies. Does anyone know how to do this? I am looking at code in my strategy, but not sure on where to make the adjustment correctly.

Who can help me with this?
