It only uses 6 bars but it has a lag of about half the detected cycle
period. So, by the time it detects a cycle, chances are it has already
come and gone. As Gary said, this lag is caused in part by the smoothing
needed to make the HilbertPeriod useful. If you remove all the smoothing
to make it more responsive, it gets so noisy you can't use it. Even
using "rocket science" smoothing methods, it will still have quite a lot
of lag.
