I seriously doubt that 100 skilled traders would fail to agree on that.
100 traders would operate on different timeframes.
A weekly view of an uptrend can have multiple countertrend days.
A countertrend day can be the start of a change in Dominance of the prior multi-day/weekly/monthly trend.
A change in Dominance in this countertrend day is first revealed on a 5min chart.
On a 5min chart, Dominance changes frequently in 3-5 bar combinations.
Since Dominance changes frequently on 5min charts, not every change in Dominance is the start of a trend that is seen on larger aggregations of time.
However the changes that ripple up through aggregations of time are seen on multi- timeframes as turns with coarser more filtered views occurring at one end of the observed spectrum and finer more detailed views at the other.
Like tuning into a radio station, any group of traders are attracted to ‘genres’ of music/talkshows that most resonates with their personality, temperament, resources, goals and lifestyle.
Although listening to multiple music stations at once can sound like noise, the cacophony can also sound like music to a trained and appreciative ear.
