Hi, in my opinion expert advisers do what they do because they use formulas of the type if A+B = C buy, but if A+B = D sell. Black or white, on or off, 0 or 1 type decision making. A little more sophisticated than that perhaps but that's the basic logic.
Fundamental data is much more subjective, and often leads to a maybe, could be, might not, sort of situation. We see this very clearly on news events sometimes when we have an initial knee jerk reaction in one direction and then once all the calculations of what the figures really mean are done the price changes direction again, and under certain conditions the same figures will give different results depending on risk appetite in the market.
How would you program that into an
EA?
Quantitative analysis I believe is better used on stocks rather than currencies and is very complicated. It would be a lot of work for no real gain in the forex world, there are much better, and more effective ways of analysing than this.
