Hi Kevin,
When I discovered AB world, I grabbed many formulas or pieces of code
and I made a tremendous mistake.
I did not note the author's name and the place where the formulas came
from. Sometimes the name was included, sometimes not.
As much as possible I quote the author's name if I know it or if I find
it easily.
Anyway I am never the inventor as my programming skill is pathetic.
Sometimes I am successful to modify the existing.
After a while I recorded more information in my own AB bible.
Sometimes its a code found in comments or in the forums, it's difficult
to remember the source.
Concerning this formula, it's a personnal mod of a modified example.
After a deep search, the chances are strong that the original was from
an archives post :
//Date: 12-January 2002 by Thomas Zmuck
//thomas.zm@xxxxxx
found into
http://www.mail-archive.com/amibroker@xxxxxxxxxxxxxxx/msg30211.html
I appreciate this formula as there is no loop.
During my research I saw also this interresting contribution into AB
library :
// Fibonacci Internal and External Retracements
// http://www.amibroker.com/members/library/detail.php?id=1084
// David K aka wooziwog
Best regards
