[Metastockusers] An even better trade binary

["Jose" <josesilva22@xxxxxxxxx>]

Either by deliberate or (more likely) poor design, sometimes a trading 
strategy can give both Long & Short signals on the same bar.

What to do then?  Ignore simultaneous entry/exit signals on the same 
bar, or take the latest signal?

The MetaStock indicator below allows the choice of either ignoring 
conflicting entry/exit signals, or taking the latest signal.

{ Note on simultaneous entry/exit on same bar:
    #1 Ignore:
         entry/exit signals cancel each other;
    #2 Preference given to:
         new entry if currently Short,
         new exit if currently Long.}
