Last week I had some fundamental conclusions which I did not stick to to the level I should have had, but the recent experiments have confirmed to me that my conclusions were sound.
A main conclusion to myself back then was: Long GBP/JPY was a sound long side, and that AUD/JPY was not a long, but rather a short or a range bound (more short than range).
I did not like to pay carry on long GBP/AUD, that is why I preferred long GBPY/JPY. In addition, AUD/JPY traded during asian sessions, so one may trade it without too much concern to about carry and boredom in waiting for market to move.
I traded it earlier today on long side, after trading it before short side, to test whether my original view was correct. It turned out to be the case. So I reversed to my original view, and I now believe my posture should remain to short AUD/JPY rallies.
I think I have a correct explanation why AUD is weak and why it makes sharp rallies, why JPY is weak, why GBP is strong, and why EUR can confuse people. I did not look at NZD, but I think it should be strong, but I have to review it carefully.
All this are opinions and analysis for myself only.
