What causes indicators to produce nuisance signals?

 

I'm fairly new to trading so apologies in advance if this is a dumb question.  I'm playing with an indi just now meant for binary trading but which seems to pick fairly profitable entries.  The problem is, when it's left to run for a prolonged period of time (all day for example) it starts to produce 'nuisance' signals.  When I change to another timeframe and back again, they disappear and it displays only the good signals - the ones you'd actually want to trade. I've attached the indicator if anyone wants to take a look.  I'm curious if this is common amongst custom indis and if it's juts bad coding and/or if there's a workaround (I tried adding an 'autorefresh' indi to the chart but that didn't seem to do anything). Any help, much appreciated.  


(I've linked to a couple of images showing the 'clean' signals and the same period with the 'nuisance' signals, just in case the images don't appear in this thread for any reason)

    The indicator is broken.

    IMHO: The best bets in a casino is Craps pass line with double odds, around 0.6%. One of the worst is American Roulette at 5.26%. Binary Options are at 30%! Forget them.
