The forex market operates on three primary structures: trend, range, and breakout. These structures help traders identify price movement patterns and make informed decisions. A trend market shows consistent upward or downward price movement, ideal for trend-following strategies. A range market occurs when prices oscillate between support and resistance levels, suitable for range trading strategies. A breakout market signifies a price movement beyond established levels, often indicating new trends or volatility spikes. Understanding these structures enables traders to align strategies with prevailing market conditions.
