At a guess, your Buy conditions can occur more than once within the
3-bar period. ExRem() doesn't get rid of the extra Buy triggers because,
in effect, the BarsSince() count begins again every time you get another
entry signal. (I understand this is technically not what happens, but
the end result is pretty much the same.) So there isn't an exit, and the
ExRem() statement never takes effect.
Look at ExRemSpan(). It eliminates extra signals for a specified period,
giving your time stop a chance to work.
