Reversal support and resistance in forex trading can be a great indicator of potential price movements and entry/exit points. Support is the level at which buying is strong enough to prevent the price from falling any further, while resistance is the level at which selling is strong enough to prevent the price from rising any further. When these levels are broken, a reversal can take place, indicating a potential shift in the direction of the trend. Reversal support and resistance can be identified using technical analysis tools such as trend lines, Fibonacci retracements, and candlestick patterns. By using these tools, traders can anticipate price movements and enter or exit positions accordingly.
