Trailing Stop Losses

I dont use this to cut losses generally but rather to save certain profits. Sometimes after a long day of trading or if I want to just look away and be happy with a trade. I will just keep a stop limit at a lower market cap that if it was to dip to I will be happy to walk away with X $. Then i just go to sleep like a baby. (Also you can do this for the way up on the chart as well ofc.
