DT:
What you are drawing are known as Babson lines (Babson
of Andrews (median line)-Babson fame). Many programs have this included as
a charting tool with fully adjustable reaction levels so that one can easily
specify percentage, Gann, Fibonacci, etc. I look at them from time to time
and sometimes they are useful. I would not be surprised if TJ does not
have plans to include them in the charting tools.

Subject: [amibroker] Oblique Fib Lines
and the historical support
Some historical support lines may be important for the next
Fib levels.
Move your cursor to the past to see the impact of previous
support lines.
