Currency strength meters can be helpful, especially for beginners who need a quick overview of market movements. However, their accuracy varies since they often rely on past data and predefined calculations, not real-time analysis. Seasoned traders generally use them as supplementary tools alongside other analyses. For reliable ones, look into TradingView indicators or Forex Factory's offerings. Commonly, they're best used for confirming trends identified through technical or fundamental analysis. Just remember, they're a supportive tool rather than a standalone strategy.
