The best thing I can say about the "waves" woo is that it forces you to wait for pullbacks in trends with the best risk reward ratio. So when it works it seems magical but retracements to fibonacci levels have been disproven time and again, with 50% being the only reliable rule of thumb, statistically speaking.

I get the principle, and it's appealing in theory, but it's far from statistically proven. If you want some other 20th century technical analysis that holds a little more water you can try Wyckoff. The supply and demand basics give a nice overview of how moves are formed and are pretty timeless.

Although there's very little predicting when the Fed will drop several trillion into the market, or when Trump has another tweetrage, so most bets are off for predicting day to day at the moment. Following trends and understanding why the consensus has formed, however, is not a terrible plan.

Perhaps more relevant to OP would be reading Wikipedia pages on money supply, currency pegging and gold backing and the interplay between interest rates and local Vs global economies. I'd guess most of what you need to know is clearly explained on Wikipedia. Given how few economists actually manage to forecast anything I'd be wary of putting much store in any one book.
