Bur first, you need to have a solid understanding of the fundamentals that drive the currency markets and be aware of the current narrative(s) that dominate the global financial markets.
Only then will you be able to figure out how news, whether economic data releases or spontaneous tweets from everyone’s favorite Tweeter-in-Chief, will move prices.
The current price is the sum total of all the known public information. When news comes out, the price fluctuates as market participants digest this new information and adjust their outlooks.
This new outlook could be supportive of your own trade outlook or against it.
Just because one favors technical analysis doesn’t mean one can ignore the fundamentals that are currently driving the currency pairs one is trading.
Traders who grasp the macro fundamentals and are attuned to the dominant market narratives or themes at the moment will minimize experiencing the “WTF just happened?!!!” moments when all of a sudden price makes a massive move up or down.
