I get that the Yen and the USD are very well correlated. What I am not sure about is the importance of the direction of the Dow, in relationship to:-
{ the tag team, and the likely success of trades made involving the G6 and the tag team}.
You may have established this during the course of this thread, but if I have seen it, I have lost track of it, or perhaps I just missed it.
I know that in theory, the Yen and the stock market indices tend to go in opposite directions and the same for the USD. And that we are looking for trades with one or more of the G6, in the opposite direction to the Yen and USD, and therefore they will usually be in the same direction as the stock market indices; in addition the Euro and GBP at least, are sometimes known as "risk currencies".
What I don't have though is any kind of mathematical feel for how well that "G6-with-stockmarket" relationship correlates, which would fit in with only taking a trade when the Dow is opposite to the tag team.
You may also have established this by long painful observation, whereas I only have a sort of subjective feel for it, and I wondered if it was here in this thread, or something you had established or discovered long ago elsewhere.
Perhaps, for example, you have empirically discovered that if you take a trade against the tag-team, and the Dow is pointing in the "wrong" direction, there is a high risk that the Yen or USD or both will turn round on you, and invalidate the trade?
Sorry, I don't think I am expressing this very clearly, but perhaps what I am asking is, is the "Dow Rule" based on theory or empirical testing?
The reason I ask is (perhaps obviously): Could it be sometimes keeping you out of trades unnecessarily?
Why I asked about the S&P was purely because (I think) it represents more of the US stock market as a whole, whereas the Dow is limited (in number, although I guess it represents huge companies). I have no idea exactly mathematically how well the S&P and Dow correlate; from casual observation, pretty well I think. I suppose if one were into backtesting, one could compare success rate of the "Dow Rule" with an "S&P Rule", not that I am into backtesting, I must admit.
Just found this, which admittedly is from 2006 and could no longer be true, but ~95% correlation between Dow and S&P at that time:
