Introduction
Although it is a matter of taste, I can't feel the truth from some article based on very few past chart. I want to read an article which has something real for improve my trading. So, at first, I try to write a something like that. And I hope that many articles based on long term back test at short period chart will be show up on this contest...
It aside this article's research theme is Simple Volume Average Indicator. Many FX-websites says that "Look the volume". But is it true? Does volume indicator has a something meaning? I can't believe that without any back data. So I did check that with back-test in decade by myself.

!!Cautions!! In the end, I could not get unbroken cache data of AUD/USD 5 mins chart from Dukascopy server. That is why there is not sample back-test result of AUD/USD in this article. Accuracy of my handmade tester which was used for this research is worse than the default tester's "Ticks - Process all ticks". But more better than the default tester's "1 Minute - 4 ticks at OHLCs". And, of course, this result is not include trading fee. If you want to know the more realistic numbers, please do yourself. And give it me please...

Conclusions
  • In long term view, I could say that SVA-Indicator was send us a good advice at all currency pairs (Fig 3 - 8).
  • Especially, when you trading a EUR/USD, GBP/USD(Fig 3), USD/CHF(Fig 5), and EUR/GBP(Fig 7) pair, you could use the SVA-Indicator for improve your trading average gain pips.
  • But, about the USD/JPY(Fig 4), USD/CAD(Fig 6), and EUR/JPY(Fig 8) pairs, it was not good in some years. So you needs to carefully to use this indicator at these currency pairs.
