How reliable are support and resistance levels for predicting price movements?

Support and resistance levels are useful tools but not guarantees. These price points where assets historically bounce up or down can help traders make decisions, but they fail frequently. Their reliability depends on several factors: how many times the price has tested that level (more tests = stronger signal), the trading volume at that level, and overall market conditions. During strong trends, prices break through these levels easily. During sideways markets, they work better. Professional traders combine support and resistance with other analysis methods like volume patterns, moving averages, and candlestick formations for better accuracy. Beginners should avoid relying solely on these levels—they're most effective as part of a comprehensive strategy that includes proper risk management and position sizing.
