To job the end of wave a few attract a trendline throughout the start out of wave one particular and the end of wave two, then extend a parallel trendline from your close of wave a person. The 3rd wave ought to full close to this parallel trendline (both a little above or beneath or at exactly the same stage). To task the top of wave five attract a trendline in the finishes of waves 2 and 4 (also called baseline) then draw two more trendlines parallel to it within the finishes of waves 1 and 3. The fifth wave should total near one particular of such parallel trendlines: close to the channel line drawn from the conclude of wave three if it extends and close on the channel line drawn in the stop of wave one if it won't prolong.
