Key takeaways
- Support is an area where buying interest has previously halted a decline; resistance is where selling has halted a rise.
- Treat levels as zones rather than exact prices, because price often overshoots by a few pips.
- A broken support level can later act as resistance, and vice versa.
- Levels show where reactions are more likely, not where they are guaranteed.

Support and resistance are among the most widely used ideas in technical analysis. They mark areas on the chart where price has repeatedly paused, turned or accelerated. Learning to spot them helps you decide where to enter, where to place a stop and where to take profit.
What support and resistance mean
Support is a price area where a falling market has previously found enough buying interest to stop or reverse. Resistance is a price area where a rising market has previously met enough selling to stall or turn lower.
Why do these areas form? Traders remember prices. If many participants bought near 1.0800 last month and the market rallied, some will look to buy there again. Others who missed the move may place orders there too. Equally, traders who bought near a high and watched price fall may sell to "get out at breakeven" when price returns, creating resistance.
How to identify levels
1. Swing highs and swing lows
Look for clear turning points where price reversed sharply. The more times price has reacted at an area, and the more visible the reaction, the more attention traders tend to give it.
2. Round numbers
Prices such as 1.1000, 1.3000 or 150.00 on USD/JPY often attract orders simply because they are memorable. They are sometimes called psychological levels.
3. Previous day, week and month highs and lows
Many traders watch these reference points, which can make them self-reinforcing.
4. Higher timeframes first
A level visible on a weekly or daily chart usually matters more than one that appears only on a 5-minute chart. Start your analysis there, as described in Technical Analysis Basics.
Zones, not lines
Price rarely turns at the exact same tick twice. Draw support and resistance as a band, perhaps 10 to 30 pips wide on a daily chart, covering the cluster of highs or lows. This avoids the frustration of a level being "broken" by two pips before price reverses.
Role reversal
When price breaks decisively through resistance, that area can later act as support on a pullback. When support breaks, it can become resistance. This is called role reversal or polarity. It happens because traders who were wrong on the break may use a return to that level to exit, and traders who missed the break may use it to enter.
Breakouts and false breakouts
A breakout occurs when price closes clearly beyond a level. A false breakout (sometimes called a fakeout) happens when price pokes through and then quickly returns. Some traders wait for a candle to close beyond the level, or for a retest, before acting. Neither method removes the risk of a failed move; it simply changes the trade-off between getting a better price and getting more confirmation.
Worked example: planning a trade around support
Assume, for illustration, that GBP/USD has bounced from a support zone between 1.2600 and 1.2620 three times. A trader plans a buy near the top of the zone.
- Entry: 1.2630
- Stop-loss: 10 pips below the bottom of the zone, at 1.2590
- Stop distance: 1.2630 − 1.2590 = 0.0040 = 40 pips
- Nearest resistance: around 1.2720
- Take-profit: 1.2710, just below resistance
- Target distance: 1.2710 − 1.2630 = 0.0080 = 80 pips
The risk-reward ratio is 40 : 80, or 1:2. Placing the stop-loss beyond the zone, rather than inside it, gives the trade room for normal noise. Placing the take-profit slightly before resistance acknowledges that sellers may appear before the exact level. You can check numbers like these with the Risk-Reward Calculator and convert pips to money with the Pip Calculator.
If price falls through 1.2590, the support zone has failed and the idea was wrong. That outcome is always possible.
Common mistakes
- Drawing too many lines. A chart covered in levels makes every price look significant. Focus on the clearest few.
- Placing stops exactly at the level. Stops sitting right on an obvious level are easily triggered by small overshoots.
- Assuming a level will hold forever. Each test can absorb orders, and levels often weaken after repeated touches.
- Ignoring the trend. Buying at support in a strong downtrend is fighting the dominant direction.
Summary
Support and resistance mark areas where buying or selling has previously been strong enough to stop price. Find them from swing points, round numbers and higher timeframes, and draw them as zones. Broken levels can switch roles. Use them to plan entries, stops and targets, but remember that any level can fail, so always define your risk before entering. The next lesson, Trendlines, applies the same idea to sloping markets.
