I have not seen a technical or statistical study yet that in my mind at least (engineering absolutes) would qualify as a legitimate predictive indicator.
I've
once seen
one (it's described in some detail in a book by Van K. Tharp, and includes more than a decade's "evidence").
This reminds me of the statistical methods used by pharmaceutical companies in performing and publishing the clinical trials necessary to apply for product licences. Typically, if a new drug
doesn't actually "work better" than the existing ones, out of every 10 or 20 clinical trials they do to test it,
one will produce an "outlier result" adducing evidence that it
does. That can be the one they choose to publish. So there's sometimes "genuine evidence" of something that isn't actually true, just "by coincidence". This serves as a reminder that the published information one reads may have been pre-selected by other people to illustrate something they want to illustrate.
I agree, of course, that moving averages are not really, in any meaningful sense of the words, a "predictive indicator"!
May I suggest to the OP that he explore using a moving average system that utilizes
multiple time frames ?
That will clearly give him far better chances.
And reading Marcel Link's book
High Probability Trading would be a very good place to start.
