Signals can sometimes be wrong, so as I have said before,
IMO its sensible to take 100 pips profit on 50% of the
position and let the balance ride with a trailing stop.

Stop was hit yesterday on the balance (at entry price),
but at least the 100 pips taken earlier is safely in
the bag.

First day signal has now triggerd short.
I would prefer to see dual confirmation,
however there is often a decent day trade
available from this signal.
