Support and Resistance: The Foundation of Technical Analysis
Support and resistance levels are the most universally used concept in trading. Learn how to identify them, why they work, and how to trade around them.
- 1Support is a price level where buying pressure has historically overcome selling pressure.
- 2Resistance is a price level where selling pressure has historically overcome buying pressure.
- 3When support breaks, it often becomes new resistance — and vice versa (role reversal).
- 4The more times a level has been tested, the more significant it is.
Support and resistance are the most fundamental concepts in technical analysis. Once you can identify these levels on a chart, you immediately have a framework for where to enter trades, place stops, and take profits.
What is Support?
Support is a price level or zone where the market has historically bounced upward. Think of it as a "floor." At this price, there are enough buyers to absorb the selling pressure and push price back up.
Why does support work? Because market participants have memory. If the price of EUR/USD bounced strongly at 1.0700 three times in the past, traders remember that level. When price approaches 1.0700 again, buyers enter aggressively (expecting the same bounce) and sellers take profits (who were short from higher up).
What is Resistance?
Resistance is the opposite — a price level acting as a "ceiling" where selling pressure has historically overwhelmed buying pressure, causing price to reverse downward.
The psychology is the same: if the market repeatedly stalls at 1.1000, traders expect it to stall again. Sellers enter at resistance expecting a reversal; buyers who entered lower take profits there.
How to Draw Support and Resistance Levels
Zoom out — Start with the weekly or daily chart to find the most significant historical levels
Look for price clusters — Areas where price bounced or reversed multiple times
Draw zones, not lines — Price rarely stops at an exact number. Draw a zone of ~10–20 pips around the key level
Focus on closes — Wicks can pierce levels; candle bodies closing above/below is more significant
Round numbers matter — 1.1000, 1.0500, 2,000 for gold — large institutions use round numbers for orders
Role Reversal: When Support Becomes Resistance
One of the most powerful concepts in technical analysis: when a support level breaks decisively, it often flips to become resistance.
Example: EUR/USD has support at 1.0800. Price breaks below 1.0800 with momentum. Now, 1.0800 becomes resistance — because traders who bought at that support level are now underwater, and many will sell when price returns to their entry to "get out even."
This role reversal provides excellent trade setups: sell the retest of broken support (now resistance), buy the retest of broken resistance (now support).
