The Jurik Composite Fractal Behaviour or CFB measure the trend strengh using a combination of duration and fractal structure.It can be computed using 24-48-96 or 192 periods of past data.
I compare here the usd/gbp future traded at the CME.
In the first image we have the cfb computed with 192 periods, the data it is then standardized, the indicator it is in the middle pane of the chart. When the CFB it is over 2 standard deviation (horizontal red line) and the Jurik Vel Oscillator (standardized) it is above 2 standard deviation and reverse its direction a signal is then generated.
Here instead we have the same indicator using 24 periods, it is clearly visible that with a shorter data used to compute the indicator the second top is missing.
