The base channel contains the origin of wave one, the end of wave two, and the extreme of wave one.
The base channel is most important, because it defines the trend.
The acceleration channel encompasses wave three.
Once prices break through the lower boundary line of the acceleration channel, we have confirmation that wave three is over and that wave four is unfolding.
The deceleration channel contains wave four.
To draw the deceleration channel, simply connect the extremes of wave three and wave (B) with a .
Take a parallel of this line, and place it on the extreme of wave (A).
