The next step is to locate a previous low or high to use for drawing an action line.
Next, a parallel line was drawn to the right of the C/L, Notice that it is the same distance from the C/L as the corresponding Action line.

One can train his eyes by drawing such set and in case of doubts/questions just ask I would try to reply.
Happy learning and wishing all mates a profitable Prosperous NEW YEAR 2018.
