Yes, and you do well my friend.Before responding to your publication, I took the time to read about "stop-loss" and it is a bit complex for me, as I have no knowledge. However it is important to know in case you need it, as according to my reading it is a way to minimize losses.
In short words however, the "stop-loss" closes your investment if your invested capital falls below a value you have prefixed.
Anyway, you will find this explained decidedly better on the web.
