Ticker&TapeSupport and resistance: the levels that matter
Prices have memory. Certain levels on a chart keep stopping a stock on the way down or holding it back on the way up. Learning to spot them helps you decide where to buy, where to put a stop and when to be patient.
What support and resistance are
Support is a price area where buying has been strong enough to stop a decline. Resistance is a price area where selling has been strong enough to stop an advance. They are zones, not exact pennies.
Picture a $50 stock that falls to $45 three times and bounces each time. Traders start to see $45 as a floor. If the same stock rallies to $55 twice and turns back, $55 becomes a ceiling.
Why they work
Support and resistance work because people remember prices. Investors who bought at $55 and watched the stock fall often want to get out at break-even. When the price returns to $55, their selling creates supply, which is resistance.
The opposite happens at support. Buyers who missed the stock at $45 are glad to get a second chance, and funds that like the company add shares at a price they already know. That demand holds the price up.
Where to look for levels
- Prior highs: the peak of an earlier advance, especially the left side of a base. This is the most important resistance for growth traders.
- Prior lows: the bottom of a previous pullback or base.
- Round numbers: $50, $100, $200. Many orders cluster there.
- Areas with lots of trading: wide sideways ranges where many shares changed hands.
- Gaps: the edges of a big price gap often act as levels. See gaps.
How to draw levels
Start on the weekly chart to see the big picture, then refine on the daily. Use the horizontal level tool on the chart and draw through the area where price turned several times. Closing prices often give cleaner levels than intraday wicks.
Less is more. Two or three well-chosen levels are better than a chart covered in lines. The more times a level has been tested, and the more volume traded there, the more it matters. A level also gets weaker each time it is hit, because the supply or demand there gets used up.
How traders use them
In growth-stock trading, the classic buy point is a stock clearing resistance at the top of a base, the pivot. Once the old ceiling is broken, the sellers there have been absorbed. Support levels help you place a stop just below a spot where buyers should show up. When support breaks on heavy volume, it is a warning that demand has dried up.
Common mistakes
- Treating a level as an exact price instead of a zone.
- Drawing so many lines that every price looks like support.
- Buying right under heavy resistance and hoping it breaks.
- Ignoring volume: a break on light volume is less reliable.
Key points
- Support stops declines, resistance stops advances, because traders remember prices.
- The best levels are prior highs and lows, round numbers and busy trading areas.
- A clean break above resistance on strong volume is the basis of the breakout buy point.
Check what you learned
Answer at least 2 of 3 correctly to complete the lesson.
1. Why does a prior high at $55 often act as resistance?
Support and resistance work because people remember prices. Sellers waiting to break even add supply when the price returns.
2. How should you treat a support or resistance level?
Levels are areas where buying or selling showed up, not exact pennies. Treating them as precise prices leads to bad stops and false alarms.
3. How does resistance relate to the classic growth-stock buy point?
Once the old ceiling is broken on strong volume, the sellers there have been absorbed. That is the basis of the breakout buy point.
