Quote from inks2002:
the center line was a contructed by two major high and low pivots on a chart. My issue is in contructing these center lines.
I do not want to influence your own discovery, so I will only answer generically.
In Andrews Action Reaction course (link above), Andrews discusses many different methods and observations like;
Pitchforks (aka median line & parallels), drawn w/ 3 alternating swing pivots
Hagopian lines (reaction lines used with forks),
Schiff median lines (aka 50% lines)
Action Reaction lines (low & high of a swing) carried forward and backward thru time parallel to original swing
10% swings, drawn like a fan from a low or high to multiple intermediate swings
low to high or high to low trendline w/ parallels capturing the intermediate swing
0 to 4 trendlines connecting the lows of two swings
skewed expanding pivots.....and lots more
John Crane uses a form of the fork w/ his version of reaction lines...has a book & DVD
Dologa uses a form of Hagopian lines on skewed expanding pivots...

Janeish has a group on Yahoo, but you MUST buy his book to join, he also has a course that teaches his methods

Spend your time SLOWLY understanding the original AR course because it covers so much and it leaves out even more for you to discover on your own if you are inquisitive. Remember most that ALL of the above are based on the work Andrews pioneered with the help of Babson and Merechal.
There is NO HOLY GRAIL in trading, if you are looking for one it is a futile search. Now go put the study time in!
