The Engulfing candle pattern in Forex trading is a powerful reversal pattern that occurs when a smaller candle is completely engulfed by a larger candle. This pattern can indicate a change in market sentiment, with the larger candle indicating a shift in momentum. Traders can use this pattern to identify potential buying or selling opportunities, with confirmation from other technical indicators or price action analysis. The Engulfing pattern is popular among traders due to its reliability and ease of identification, making it a useful tool in any trading strategy.
