I see from your other posts that you work full time and so you are not really in the position to watch your trades closely each day. For me that highlights the fact that you should be trading with stops in place.
If your current broker does not offer that functionality it would seem in your best interests trade with one that does.
Regular orders do get cleared out overnight. But you can place a conditional sell order that will sit in the system for up to 90 days. If you visit the page where you can set your trailing stops you should also see that functionality.
