What is Support in Stock Market?
Support is a price level where a falling stock usually stops dropping and starts moving upward again.
You can think of support as a floor under the stock price. When the price reaches this level, buyers become active and try to push the price higher.
Simple Example of Support
Imagine dropping a ball on the floor. The floor stops the ball from falling further and the ball bounces back upward.
The stock market behaves in a similar way:
- Price keeps falling
- Buyers see the stock as cheap
- Demand increases
- The stock price bounces upward
That area where the price stops falling is called Support.
Why Support Happens
- Buyers enter the market
- Investors think the stock is undervalued
- Demand becomes stronger than selling pressure
- Market confidence increases

What is Resistance in Stock Market?
Resistance is a price level where a rising stock usually stops going higher and starts falling downward.
You can think of resistance as a ceiling above the stock price.
Simple Example of Resistance
If you throw a ball upward toward the ceiling, it hits the ceiling and comes back down.
In the stock market:
- Price keeps rising
- Sellers become active
- Investors book profits
- The stock starts falling
That upper level is called Resistance.
Why Resistance Happens
- Traders start selling
- Profit booking increases
- Supply becomes stronger than demand
- Buyers become weaker
Market Psychology Behind Support and Resistance
Support and resistance work mainly because of human emotions and trader psychology.
The market remembers important price levels. Traders react to these levels again and again.
Main Groups of Traders
1. Buyers (Bulls)
These traders bought near support earlier and made profits. When price returns to the same level, they buy again.
2. Sellers (Bears)
These traders sold near resistance previously. They try to sell again when the price revisits the same area.
3. Waiting Traders
Some traders miss earlier opportunities. When price returns to important levels, they quickly enter the market.
Because thousands of traders watch the same levels, support and resistance become stronger over time.
Types of Support and Resistance
1. Horizontal Support and Resistance
This is the most common type.
| Type | Description |
|---|---|
| Horizontal Support | Price repeatedly bounces upward from the same lower level. |
| Horizontal Resistance | Price repeatedly falls from the same upper level. |
2. Trendline Support and Resistance
Trendlines are diagonal lines used in trending markets.
- In an uptrend, the trendline acts as support.
- In a downtrend, the trendline acts as resistance.
3. Moving Average Support and Resistance
Many professional traders use:
- 50 EMA
- 100 EMA
- 200 SMA
These moving averages often act as dynamic support and resistance zones.
