Module 5 · Lesson 3 of 8Support and resistance are price areas where the market has paused or reversed before. Trendlines connect the turning points of a move. Used carefully, they give you reference points for planning trades.
Risk warning: CFDs are complex instruments and come with a high risk of losing money rapidly due to leverage. You should consider whether you understand how CFDs work and whether you can afford to take the high risk of losing your money. Educational content only.

Support is a price area below the market where buying interest has previously been strong enough to stop a fall. Resistance is an area above the market where selling interest has previously stopped a rise. The basic chart-reading lesson introduced these ideas. Here we go deeper into how to use them.
Think of a ball bouncing in a room. The floor is support and the ceiling is resistance. Price can bounce between them for a long time. When it finally pushes through one, the market has changed its mind about fair value, at least for now.
Why might levels matter at all? Partly because many traders watch the same obvious areas, partly because people remember prices where they were stuck in a losing trade and want to get out at break-even, and partly because orders (such as stop-losses and pending orders) tend to cluster near round numbers and previous highs and lows. None of this is certain. It simply makes some areas more interesting than others.
Beginners often draw a razor-thin line and then feel cheated when price goes a little past it. Real markets are untidy. It is more realistic to treat a level as a zone: a band covering the area where several turning points occurred.
Hypothetical gold prices. Price turned down at $2,055, $2,060 and $2,052 on three separate occasions. Instead of one line at $2,060, a trader draws a resistance zone from about $2,050 to $2,062. A candle that pokes to $2,058 and falls back has still "respected" the zone. A stop-loss placed at $2,061 would be inside the zone and easily hit by noise, so a trader using this idea might place it beyond the zone and size the position accordingly.
Prices like $2,000 or $2,050 often attract attention simply because people like round figures. Treat them as areas of interest, not certainties.
When price closes decisively through a level, that is a breakout. A frequent observation is role reversal: old resistance that has been broken may act as new support, and old support that has been broken may act as new resistance. The reasoning is that traders who missed the move wait for price to come back and test the old level.
| Event | What it looks like | What traders often watch for |
|---|---|---|
| Bounce | Price touches a zone and turns away | Rejection candles, a fresh swing high or low |
| Breakout | Candles close beyond the zone | Strong body, rising activity, follow-through |
| Retest | Price returns to the broken zone | Whether it holds as the new support or resistance |
| False breakout | Price pokes through, then closes back inside | A quick reversal that traps late entrants |
A false breakout (sometimes called a fakeout) is common and is one reason many traders wait for a candle to close beyond a level instead of reacting to a brief spike. Waiting costs some of the move, but it avoids some of the traps. There is always a trade-off, and neither way is right every time.
A trendline is a straight line connecting turning points. In an uptrend, price makes higher lows, so you draw the line under those lows. In a downtrend, price makes lower highs, so you draw the line above them.
Hypothetical uptrend on an hourly chart. Lows form at $2,000, $2,010 and $2,020 at roughly equal time intervals. The line rises about $10 per interval, so the next touch might be expected near $2,030. If price instead closes well below the line, say at $2,018, the pattern of higher lows has been interrupted. That does not tell you a downtrend has begun. It tells you the old assumption needs to be reviewed.
Levels help most with planning: where would the idea be proved wrong (a sensible place for a stop-loss) and where might price meet resistance (a sensible area to consider a target). See Stop-Loss and Take-Profit for how to turn those into orders.
Common mistakes
Levels turn a messy chart into a plan with defined risk. They are tools for thinking, not predictions. Leveraged trading can lose money quickly, so always decide where you are wrong before you enter.
No. Levels fail regularly, especially around news. They are areas of interest, not barriers, so you need a plan for when they break.
Start on a higher timeframe such as the daily chart to find the major levels, then zoom in. Higher timeframe levels usually carry more weight than levels on very short charts.
