What Is Support and Resistance?
Support and resistance are the most fundamental concepts in technical analysis. Every chart pattern, every setup, and every indicator comes back to these two ideas.

Support is a price level where buying pressure is historically strong enough to prevent the price from falling further — the floor. Resistance is a price level where selling pressure is historically strong enough to prevent the price from rising further — the ceiling. Every chart, in every market, in every timeframe, has support and resistance levels. Learning to identify them accurately is one of the highest-leverage skills in trading.
Why Support and Resistance Exist
Support and resistance are psychological phenomena as much as technical ones. They exist because traders remember price levels. When a stock bounces off $50 three times, thousands of traders mark $50 as significant. When the stock returns to $50, those traders make decisions based on that level — some buy at the 'proven support', others set stop losses below it. This self-fulfilling concentration of decisions at specific levels is what creates the support and resistance you see on charts.
How to Identify Strong Levels
Not all support and resistance levels are equal. Strong levels have: (1) Multiple touches — the more times price has tested and respected a level, the more significant it is. (2) Strong reactions — levels that produced sharp, fast reversals are more significant than ones that produced slow grinds. (3) High-volume tests — if the level was tested on high volume and held, the buying/selling at that level was significant. (4) Confluence — a price level that aligns with a round number, a moving average, and a previous major high is far more significant than one with only one supporting factor.
Role Reversal: Support Becomes Resistance
One of the most reliable and powerful concepts in technical analysis: when a support level breaks, it typically becomes resistance, and when a resistance level breaks, it typically becomes support. If a stock holds $50 as support for months and then breaks down through it, $50 becomes the new resistance — because traders who bought at $50 are now trapped at a loss and will often sell at breakeven when the price returns to $50. This role reversal is the foundation of many successful trading strategies and explains why re-tests of broken levels are such reliable entry points.
