Support and Resistance

In the previous lessons, you learned to read candlesticks and recognize patterns. But a hammer candle in the middle of a chart doesn't tell you much — the same candle at a price level where buyers have stepped in before is a completely different signal. This lesson introduces support and resistance: the price levels that give candlestick patterns their meaning.

What Is Support?

Support is a price level where buying pressure tends to appear. Think of it as a floor: the price drops toward it and bounces. When a stock drops to $100 and recovers — then drops to $100 again and recovers again — $100 is acting as support.

In this chart, the price drops to $100 multiple times and bounces each time. The green dashed line marks the support level — every time the price reaches this floor, buyers step in and push it back up.

What Is Resistance?

Resistance is the opposite — a price level where selling pressure tends to appear. Think of it as a ceiling: the price rises toward it and gets pushed back down. If a stock keeps rallying to $75 but can't break through, $75 is acting as resistance.

Here the price reaches the $75 area twice and gets rejected each time. Sellers are consistently defending this level, creating a ceiling that the price can't break through.

How to Find These Levels

Start simple: look for prices that the market has tested multiple times. Draw horizontal lines at obvious bounce points. You don't need sophisticated tools — if you can see that the price keeps reacting at the same level, you've found support or resistance.

At least two touches make a level notable. Three or more make it significant. The more times a level is tested and holds, the more traders are watching it — which makes it even more likely to hold again.

Spot the Level

Why These Levels Work

Support and resistance work because of how traders behave. When the price bounces off a level, people notice. Traders who bought there before feel validated. Traders who missed the bounce set orders to buy if the price returns. The more people watching the same level, the more orders cluster there — and those orders create the buying or selling pressure that makes the level hold. It's partly a self-fulfilling prophecy: the level works because enough traders believe it will.

Psychological levels like round numbers — $100, $50, $10,000 — are a good example of this. Humans naturally anchor to round figures. Many traders set their buy and sell orders at these numbers, which creates support or resistance even without historical price action at that exact level. The level exists because of collective behavior, not because of anything intrinsic about the price.

When Levels Break: Breakouts and Role Reversal

Support and resistance don't hold forever. Sometimes the price pushes through — this is called a breakout. Breakouts often lead to strong moves because all the traders who were betting the level would hold are now wrong, and their exit orders add fuel to the move.

A key concept: when a resistance level breaks, it often becomes support — and vice versa. This is called role reversal. If the price breaks above $100 resistance, traders who missed the breakout will see pullbacks to $100 as a buying opportunity. The old ceiling becomes the new floor.

In this chart, the price tested $100 resistance multiple times, then broke through with a strong candle. On the pullback, $100 held as support — the old ceiling became the new floor.

Test Your Understanding

Key Takeaways

• Support is a floor where buying pressure appears; resistance is a ceiling where selling pressure appears.
• The more times a level is tested and holds, the more significant it becomes.
• When levels break, they often reverse roles: old resistance becomes new support, and vice versa.

You can now read candles, recognize patterns, and identify key price levels. Next up: trends — the general direction the market is moving between those levels.
