In my experience actively trading listed stocks during the day it was best to work with mental stops. Only enter the order when your stop price was hit.
I only used physical stops if I had to be away for a few minutes (e.g., potty run). I can't tell you how many times the specialist ran my stop. Bam! Hit it and right back to the previous price level. Got to where I damn near peed my pants sometimes when I was in a trade. Or I'd put the stop so far away only a market disaster would get to it.
When I've got a position trade on (with appropriate stop levels for the longer time-frames) I'll use physical, OCO target and stop loss orders. They work fairly well. You will get the occasional run at the open, but I just don't like staring at open positions all day. It causes me too much consternation.
