Hallo people,
I'm pretty new here, and just got this by "googling" around for finding the "real" ADX indicator for MT4. It was actually a long and hard quest, because there are dozens of wrong ones (without speaking of the "standard", included in the distribution).
Thank you very much mladen, because "your is it!", precisely coded as per p.35 of the book. I was almost desperate and wanted to make such a thing, but fortunately one doesn't have always to re-invent the wheel.
I also appreciated very much your comment on "the" book. If you are interested (we will be surely interested in your opinions and help) I belong to a small community of people having the book, having read it several times, and putting quite a lot of efforts for "refreshing" and profitably applying Wilder's methods to today markets. You find us in the other forum:
Trading Systems in 'New Concepts In Technical Trading Systems' by J. Welles Wilder, and you probably can immediately see that we are quite active. You hopefully don't mind that I will make some advertisment of your indicator and credit your merits.
I sincerely hope this link is not disturbing anybody, because that other forum has a quite different focus (it's not oriented towards metatrader and "computerized" trading). And I did not find any precise rule here against posting links.
Thank you again, and perhaps see you soon!
F.
