Support is a price area where buying has previously been strong enough to stop a fall. Resistance is where selling has stopped a rise. They are zones rather than exact lines, they matter more with each additional touch and on higher timeframes, and a broken support level often becomes resistance afterwards — a role reversal called a flip.
Support is an area where buying has stopped a fall. Resistance is an area where selling has stopped a rise.
These are the most useful lines on any chart, and the most commonly drawn wrong. Understanding why they work tells you how to draw them, so start there.
Why price reacts at old levels
There is nothing mystical about it. Three groups of traders want the same price for different reasons.
Suppose price fell to 1.0800, bounced hard, and rallied 200 pips. Later it comes back to 1.0800.
- Traders who bought that first bounce and closed early want to buy again — they watched it work.
- Traders who missed the bounce have been waiting for a second chance at that price.
- Traders who sold near the low and got hurt want out at breakeven, which means buying back at 1.0800.
Three different motivations, one price. Orders pile up there, and price reacts.
Draw zones, not lines
The most common beginner error is treating a level as one exact price.
Look at any level touched several times and the touches will not line up perfectly — one wick overshoots, one reversal falls short. That scatter is the level. Its width tells you the range in which participants were willing to act.
How to draw one:
- Find at least two reversals at roughly the same price
- Use the candle bodies for the core — bodies are where price settled
- Use the wicks for the outer edge — wicks show where the fight happened
- Draw the band
This matters directly for stop placement. A stop inside a support zone is not protected by that zone — it sits in the area where the fight is expected.
What makes a level important
Not all levels deserve equal attention. Four things increase weight:
Timeframe. A daily level beats a 15-minute one, for the reason in Part 3 — more participants formed it.
Number of touches. Two is minimum, three or more confirms. But note the tension: each test uses up orders. A level tested seven times is well established and progressively weaker, which is why heavily tested levels eventually break.
Reaction strength. A level that produced a sharp 200-pip reversal matters more than one that produced a 20-pip pause.
Recency. Last week’s level is fresher in people’s minds than one from three years ago.
The flip: support becomes resistance
This is one of the more dependable behaviours on a chart, and it gives beginners some of the cleanest setups available.
When support breaks, it frequently becomes resistance. When resistance breaks, it frequently becomes support.
The mechanism is the same order logic as before, with the groups reversed. Buyers who defended the old support are now underwater and sell into a return to that price. Traders who sold the break want to add on a retest. Both act at the same level, from the opposite side.
The flip is valuable because the point of being wrong is unusually clear: if price closes back through the flipped level, the read was wrong.
Key takeaway A level is not a prediction that price will turn. It is a place where a reaction is more likely and — more usefully — where you know exactly what “wrong” looks like. That second property is what makes levels tradeable at all.
Round numbers
Prices ending in round figures — 1.1000, 150.00, 2,400 — attract orders for no reason beyond humans liking round numbers. Standing orders and stop placements gather there.
The practical consequence: place stops beyond a round number, never exactly on it. Clustered stops are visible liquidity, and price reaches for them more often than chance would suggest.
Automate the watching
You do not need to sit at a chart waiting for price to reach a level. Mark your zones in a calm moment, then set a Market Watcher alert at each one. The alert brings you back at the price you cared about.
That habit also prevents a problem covered later in the course: watching a chart for hours is what produces impatient trades.
Next: Trendlines and channels — the same logic applied to levels that move.
- Support and resistance are zones, so draw them with width rather than as single lines.
- A level matters more with each touch and on higher timeframes.
- Broken support commonly becomes resistance, and broken resistance becomes support.
- Round numbers attract clustered orders, so stops belong beyond them rather than on them.
