Support
A price area where buying interest has historically been strong enough to slow or temporarily stop a decline.
- Potential buying-pressure zone
- Often forms after previous declines
- Price may react around the area
What Are Support and Resistance?
Support and resistance are core ideas in technical analysis. They are price areas on a chart where the market has previously paused, slowed or turned. Traders mark these areas to understand where buying or selling interest has shown up before. They are better treated as zones than as perfectly precise prices.
Resistance
A price area where selling interest has historically been strong enough to slow or temporarily stop a rise.
- Potential selling-pressure zone
- Often forms after previous advances
- Price may react around the area
How Support and Resistance Levels Form
There is no single cause. These are the common ways traders notice support and resistance levels.
1
Previous Highs & Lows
Earlier swing highs can act as resistance, and earlier swing lows can act as support.
2
Multiple Price Reactions
When price reacts around a similar area repeatedly, the level becomes more noticeable on the chart.
3
Psychological Levels
Round numbers such as ₹100, ₹500 or ₹1,000 may attract attention, but they are not guaranteed to act as support or resistance.
4
Trendlines
Rising trendlines may act as dynamic support. Falling trendlines may act as dynamic resistance.
5
Moving Averages
Some traders observe moving averages as potential dynamic support or resistance.
Support and Resistance on a Price Chart
In this illustrative chart, price repeatedly reacts near a lower zone (support) and an upper zone (resistance). Hollow candles close higher than they open; filled candles close lower.
Support and resistance are areas of potential reaction, not guaranteed turning points.
Breakout and Breakdown
Levels do not hold forever. Price can move through them, and that is where the terms breakout and breakdown come from.
Breakout
Price moves above a resistance area.
Resistance→Price moves above→Potential breakout
Breakdown
Price moves below a support area.
Support→Price moves below→Potential breakdown
A brief move beyond a level can turn out to be a false breakout or false breakdown, so traders often look for confirmation. Not every breakout leads to a sustained rise, and not every breakdown leads to a sustained fall.
Role Reversal
After price moves through a level, traders sometimes watch whether the old level starts to behave in the opposite way.
Resistance becomes support
Resistance→Breakout→May later act as support
Support becomes resistance
Support→Breakdown→May later act as resistance
This behavior can occur, but it is not guaranteed.
How to Identify Support and Resistance Levels
A simple, repeatable process for marking levels on a chart.
- 1
Look at historical price movement.
- 2
Identify major swing highs and swing lows.
- 3
Look for areas with repeated reactions.
- 4
Mark zones rather than exact single prices.
- 5
Check the broader trend and timeframe.
- 6
Look for confirmation before interpreting a breakout or breakdown.
Different traders may identify slightly different levels from the same chart.
Support vs Resistance
| Feature | Support | Resistance |
|---|---|---|
| Definition | Area where buying interest may slow or pause a decline | Area where selling interest may slow or pause a rise |
| Typical location | Below the current price | Above the current price |
| Price behavior | Price may pause or bounce | Price may pause or turn lower |
| Common chart reference | Previous swing lows | Previous swing highs |
| After breakout/breakdown | After a breakdown, may later act as resistance | After a breakout, may later act as support |
Static vs Dynamic Support and Resistance
Both approaches are commonly used in technical analysis, and many traders look at them together.
Static
- Previous highs and lows
- Horizontal price zones
- Historical levels that stay fixed on the chart
Dynamic
- Moving averages
- Trendlines
- Levels that change as price and time change
Common Mistakes
Exact prices. Treating levels as exact prices instead of zones.
Assuming it holds. Believing every level will hold.
False breakouts. Ignoring that a break can fail.
Too many levels. Drawing so many lines the chart becomes noise.
One timeframe. Looking at only one timeframe.
No context. Ignoring the broader market context.
Past = future. Assuming historical reactions guarantee future ones.

“Resistance always causes price to fall.”
FACTResistance may slow or temporarily stop an advance, but price can break through it.

Support and Resistance FAQs
Support is a price area where buying interest has historically been strong enough to slow or temporarily stop a decline. Traders often mark it near previous swing lows. It is best treated as a zone, and price may or may not react there again.
Resistance is a price area where selling interest has historically been strong enough to slow or temporarily stop a rise. Traders often mark it near previous swing highs. Price can pause there, but it can also move through it.
Support is a potential buying-pressure zone that sits below the current price and may slow declines. Resistance is a potential selling-pressure zone that sits above the current price and may slow advances. Both are areas of possible reaction, not guaranteed turning points.
A breakout happens when price moves above a resistance area. Because a brief move above a level can fail, traders often look for confirmation. A breakout does not guarantee that price will keep rising.
