Here's another example... I do it this way to keep my analysis at the higher level. In truth, the final falling red is iffy (at forest level), until price leaves the formation either way. At the forest level, I don't let a temporary pause in price affect the Forest Gaussian, just the lower levels.
The price is moved by the market (traders') sentiment about the future. Different size groups have different sentiments that change at various speeds: on various fractals. The chart resolution (i.e. 5 min bars) acts as a sampler of the continuous price waveform, and filters out frequencies higher than half of the sampling frequency: low-band-pass filter. Chart frequency (resolution): 5 min bars, 2 min bars, etc..
I guess, from the two parallel trend lines that define a channel one is the right (proper) one, and the other one what's left. Hence RTL & LTL ... As St. Michael (Travolta) said: the antonym of "white" is "yolk"!
