1) having spent a lifetime making things simpler and better for a living, once I clearly understood Fisher's scoring concepts, I decided having what, 16 criteria(?), was not necessary. I reduced it to 6, did a correlation analysis with the original scoring system, and got something like 0.93 across a range of instruments. My A confirms at +5/-5. My 5 day confirms at +3/-3. Since people here talk about the number rather than the status, I speak a different language.
2) from the 2 books on currencies you recommended, I got the concept of measuring value of all currencies against a single entity, gold. Up to now I'm not sure how to use it as values don't shift much. All saw your suggestion, nobody in the history of this thread has talked about it. Maybe it is useless, I don't know.
3) from the 2 books and my knowledge of ACD, I created my own index to compare 23 currencies against each other. Just as you have proprietary research that you have openly said is not for sharing, mine falls in the same category.
Beyond that, what can I contribute? If someone asks the same question for the 21st time in this thread and I see it is genuine and not the fruit of a lazy feed me mentality, I answer the question. This is not a thread about calls as you made very clear. I could have said I found indices boring as hell for quite a while now and won't touch them, but there are people here who want to trade indices every day and really don't give a shit what I think about them. They might if you told them, but I'm not you.
So yeah, I guess I'm saying within the limits I have described, tell me how and I'll be happy to contribute. But if you want to talk about +5 or +10, sorry, I have no idea what that is anymore.
Edit: sorry, forgot to mention, when I talk of 5 or 3, those are rounded values. I added something to the basic scoring.
