Recognizing price action signals in forex trading involves analyzing patterns and movements in the market without relying on technical indicators. Common price action signals include candlestick patterns, such as doji, engulfing, and hammer patterns, as well as trend lines, support and resistance levels, and chart patterns, such as triangles and head and shoulders patterns. Traders who use price action analysis often rely on visual analysis of the market and use historical price data to identify potential opportunities and patterns. It is important to note that price action analysis requires a deep understanding of market dynamics and may take time to master.
