All of your questions can be rolled into one question: How is fundamental analysis applied to the currency market?
Most of the people on this Forum are technical traders, not fundamental traders. So, if they were to address your question, their answer would have to be: I have no idea.
Technical traders basically use this methodology:
(1) we almost never know all of the forces driving price in a particular market,
(2) we have found that it is impossible to consistently predict how the market will react to specific news events, and therefore
(3) we believe that it is impossible to predict, at any time, the direction of the market or the duration of any trend
What we do instead is wait for the major players in the market to reach a consensus among themselves about the correct price level, under present conditions. When the major players have decided a direction for the market, we try to follow them in that direction.
Having said all that, there are fundamental currency traders. In fact, there is a forum here on this site devoted to fundamental analysis and discussion. You might ask your questions there.
Kathy Lien has written an interesting article on factors that move the currency market. I’ve attached the .pdf of her article, below.
Investopedia has a similar article by Boris Schlossberg and Kathy Lien:
Investopedia - Free Report - Five Key Factors that Move the Forex Markets
Most of us have studied these articles, and most of us agree that they provide interesting background information. But, using them to make successful trades on a consistent basis has proven to be impossible.
No doubt, Kathy Lien would strongly disagree with that opinion.
I don’t agree with traders who mock fundamental analysis — I’ve heard it referred to as fuzzy-mental analysis. That’s a funny expression, but not very helpful when you’re trying to decide how to trade.
There is no question that both technicals and fundamentals move currency prices. In both cases, the problem for us little guys is that it’s the BIG GUYS who decide which technical factors and which fundamental factors to react to.
We can try to out-guess the BIG GUYS , but we play that game at our peril.
