What are support and resistance, and how do you draw them?
Support is a price where a falling stock has stopped and turned up before, because buyers stepped in. Resistance is a price where a rising stock has stopped and turned down, because sellers stepped in. Draw them through repeated swing lows and highs on the daily chart, and treat them as zones, not exact prices.
- 1Tap the chart where price turned more than once. You can draw three lines.
- 2Press “Check my lines” to count how many swing highs and lows each line touches.
- 3Show the key levels and find the breakout: watch old resistance act as support on the retest.
What support and resistance are
Prices remember. If buyers stepped in at ₹450 twice before, many traders will watch ₹450 again. That shared memory is why levels work at all.
- Support: a level below the current price where falls have stopped before. Demand outweighed supply there.
- Resistance: a level above the current price where rises have stopped before. Supply outweighed demand there.
Levels are the base of almost everything else in swing trading: where you enter, where you put the stop and where you take profit.
How to draw support and resistance
- 1Use the daily chart and look back six months to a year.
- 2Mark the obvious swing lows and swing highs — the turning points you'd notice from across the room.
- 3Look for prices where two or more turning points line up. Draw a horizontal line through them.
- 4Treat each line as a small zone. Price often turns a little above or below it.
- 5Keep only the three or four levels nearest to today's price. A chart full of lines helps no one.
In the lab above, tap to draw your lines first, then use Check my lines to see how many swing points each one touches.
What makes a level stronger
| Stronger level | Weaker level |
|---|---|
| Several clear turning points | One touch |
| Sharp moves away from it | Slow drifts through it |
| Recent | Years old |
| Visible on the daily and weekly charts | Only on a 5-minute chart |
Round numbers such as ₹500 or ₹1,000 often act as levels too, simply because many people place orders there.
A level also gets stronger when other tools agree with it. If a horizontal support line sits at the same price as the rising 50-day EMA, or at the top of a demand zone, more traders are watching the same area for different reasons. Swing traders call this confluence, and it is often where the cleanest entries come from.
When resistance becomes support
When price breaks above resistance and holds, that old resistance often becomes new support. Traders who missed the breakout buy the pullback to it, and those who sold there earlier may buy back. This is called role reversal.
The practice chart in the lab includes one: price breaks above its ceiling, comes back to test it from above, and turns up again. A retest like this is one of the cleaner places to plan an entry. The same idea, drawn as a zone around the base of a sharp move, is a demand zone.
Planning a trade with levels
- Support
- ₹450
- Resistance
- ₹520
- Entry
- ₹455, as price turns up from support
- Stop-loss
- ₹440, below the support zone
- Target
- ₹515, just under resistance
- Risk / reward per share
- ₹15 / ₹60
The stop sits where the idea is wrong — support broke — and the target sits where sellers appeared before. Size it with the position size calculator.
Put the stop a little beyond the level, not exactly on it, and the target a little before the next level, not exactly on it.
Bounce or breakout: two ways to trade a level
Every level gives you two possible trades. Decide which one you are taking before price gets there.
| Bounce trade | Breakout trade | |
|---|---|---|
| Idea | The level holds and price turns | The level gives way and price runs |
| Where you buy | Near support, after a sign buyers are back | Above resistance, after a daily close beyond it |
| Stop-loss | A little below the support zone | Back inside the old range, below the breakout candle |
| Target | Just under the next resistance | The next resistance above, often older and further away |
| Main risk | Support breaks | False breakout: price falls back inside |
A useful filter: in an uptrend, favour bounces from support and breakouts through resistance. In a downtrend, both are harder, and sitting out is a valid choice.
How to confirm a level is holding
Price touching a level is not enough. You want evidence that the buyers who stepped in before are stepping in again.
- A rejection candle: a hammer or long lower wick that dips into support and closes back above it. See candlestick patterns.
- A close back above: price may poke below support during the day. What matters on the daily chart is where it closes.
- Slowing selling: smaller red candles and lighter volume as price nears the level show sellers running out of steam.
- A higher low: if the next dip stops above the previous one, buyers are getting more eager.
And know what invalidation looks like. A daily close clearly below the support zone, especially on heavy volume, means the level failed. That is where your stop belongs.
Indian market details that affect levels
- Overnight gaps: results and news often land after market hours. A stock can open below your support, so your stop-loss fills at the open price, not at your stop. Plan for some slippage, and avoid holding a fresh trade through a results date if the gap risk worries you.
- 52-week highs and lows: these are watched by a very large number of traders and show up on every broker app. They often behave as levels.
- Round numbers: ₹100, ₹500 and ₹1,000 levels attract orders. Put your stop a little beyond the round number, not exactly on it.
- Circuit limits: a stock frozen at its lower circuit can blow straight through support without you being able to exit. Smaller, illiquid stocks carry this risk more often.
Common mistakes with support and resistance
- Drawing too many lines. If every price is a level, none of them is. Keep the three or four nearest to today's price.
- Using exact prices. Expecting a turn at exactly ₹450.00 gets you stopped out by a ₹2 dip. Think in zones.
- Forcing levels from old data. A level from five years ago matters far less than one from last quarter.
- Placing the stop right on the level. That is exactly where everyone else's stop sits. Give it a little room.
- Ignoring the trend. Buying support in a falling stock means trading against the bigger move. Each test tends to weaken the level.
Draw the levels on a weekend, when the market is closed. Write down the bounce and breakout plan for each. During the week, you only need to check whether price reached them.

Common questions
Should I draw support and resistance as lines or zones?
Zones. Price rarely turns at the exact same paisa. Draw a line through the turning points, but expect price to react a little above or below it.
Which timeframe is best for support and resistance?
For swing trading, the daily chart. Check the weekly chart too — a level that shows on both is worth more.
How many times can a level be tested?
There's no fixed number. Each test uses up some of the orders waiting there, so a level touched many times can eventually break.
What's the difference between support and a demand zone?
Support is a price where falls have stopped. A demand zone is a narrow area at the base of a sharp rally, where unfilled buy orders may still sit. They often overlap.
What happens when support breaks?
Buyers who held it are now trapped in losing trades, and many sell on the way back up. That is why broken support often turns into resistance. If you were long, a close below support is usually where your stop-loss should be.
Are moving averages support and resistance?
They can act like moving levels. In a steady uptrend, many swing traders watch the 20 or 50-day EMA as dynamic support. See the guide to the best EMA for swing trading.
Is a breakout above resistance a buy signal?
It is a reason to look, not a signal on its own. Check that the daily close is above the level, that volume rose, and that the next resistance is far enough away to make the risk worth taking.
Support and resistance kaise nikale?
Daily chart par woh swing lows aur highs dhundhiye jahan price do ya zyada baar palta ho. Unke through horizontal line kheenchiye aur use ek chhota zone samjhiye, exact price nahi.
