andrasm, Do you mean that one should use trailing stops on multiday basis? - meaning not going flat at 4pm.
I am in favor of overnights in gerneral if you are right, never with loser. Now things are very shaky so it's a special situation - I would NOT take anything home for a while..... The problem is; at nights the markets are so thin, that bigger traders can manipulate it. Especially now that we can have all sorts of political news etc. So the brokers on Globex don't recommend stops. You can take option positions to protect your futures overnight. However there is a cost of that.
