Here is an alternative.
The first method was increasing the smoothing period for every
trendy day, from the beginning till the end.
It will do it even if the trend lasts 3 or 13 or 53
bars.
A more realistic approach is to increase the period AFTER some
threshhold bars.
Keep the smoothing fast up to the 20th trendy bar and
then increase the period to stay more in the market and enjoy
the last [and the most interesting] part of the [prolonged]
trend.
This will help to ignore the premature exit signals, ignore
the probable first pull-backs and catch the usual double peak
formation, but, the code will examine this possible scenario
AFTER the 20 confirmed trend bars.
The gif speaks better :
The initial trend detector is the
black DEMA(StochD(40),20).
The variable detector stays closely for the first 20 bars and
then changes to a much slower mode.[green-red line]
The obvious benefit is to ignore premature exit at the first
peak P1, re-entry at R1 and goes to a final exit at P2.
