The best timeframes for trading Forex depend on your trading style and strategy. For day traders, short-term timeframes like the 15-minute, 30-minute, or 1-hour charts are popular for quick, frequent trades. Swing traders often prefer 4-hour or daily charts, looking for longer-term trends. Scalpers may use even shorter timeframes like 1-minute or 5-minute charts to capture small price movements. Ultimately, the right timeframe aligns with your trading goals, risk tolerance, and availability to monitor the markets.
