False signals are easy to detect because you have an arrow signal but the 
FxBay MACD on the next brick doesn't correspond because the zero line of
the FxBay MACD has not been crossed.

Missing signals are not easy to detect because there is no arrow, no alert
message and no alert sound. The only way to detect a missing signal is
to be looking at the chart when it happens and to see that if a signal had
been there the signal would have been good since the FxBay MACD zero
line has been crossed on the next brick validating the signal. 

Although this is rare it does happens. If a trader had detected the missing
signal on the attached chart the trader would have earned 17 bricks.
