When period is set, it's time to search form extreme price swings within that period as in attached picture: search for extreme low and high within period, mark them and use method shown in picture - move first extreme price point (which occured first) to the far side of the period and second extreme price point move to the center of the period; next connect those two points with straight line and you got first segment of the monowave.
Do the same with the second period and you'll get second segment.
Finally you connect those two segment with the third in order to get continuous sequence of segments.
Remember that monowave is number of segment from one price change till another. In picture first monowave will consist of only one segment (1 segment) and the second one will have two segments, because 3rd and 2nd segments move in the same direction.
Hope you got the idea. If not, please dont hesitate to ask.
