Welcome to the world of forex trading! Price Action trading can indeed be effective, but it's not one-size-fits-all. Generally, it works well with medium and highly volatile assets like GBPUSD and EURUSD, as well as other major currency pairs. The Price Action system relies on chart patterns and historical price movements, which major pairs tend to exhibit more predictably. I wouldn't recommend applying Price Action patterns to minor cross rates or exotic currency pairs. Exotic currencies can be quite unpredictable due to factors like central bank interventions or economic sanctions against specific countries. It's important to focus on more stable pairs when using Price Action strategies. For a more detailed understanding of Price Action trading, I'd recommend checking out this resource
