Support & Resistance

In one line: Price often stops falling at a floor (support) and stops rising at a ceiling (resistance) — and these levels help you plan your trades.

🎯 What you'll learn

What support and resistance (S/R) mean in simple words.
Why these levels form again and again.
How old floors become ceilings, and old ceilings become floors.
How to draw S/R and how to use them.

📘 Key concepts

What is support and resistance?

S/R (support and resistance) are price zones where the market often changes direction.

Support = a price floor. Here buyers (people who want to buy) tend to step in. Their buying can stop the price from falling more.
Resistance = a price ceiling. Here sellers (people who want to sell) tend to step in. Their selling can stop the price from rising more.
Think of a ball in a room. It bounces off the floor and stops at the ceiling. Price acts the same way.

Why these levels form

Levels form because price has a memory. Many orders (buy/sell requests) gather at the same spots.

People remember, "Last time it stopped at ₹100 and went up." So they buy near ₹100 again.
Others think, "It kept failing at ₹150." So they sell near ₹150 again.
Round numbers (like 100, 500, 1000) act as natural magnets. Our minds like clean numbers.
More touches = a stronger level. A price the market tested many times matters more.

Role reversal (the flip)

This is very important. When a level breaks, it often swaps its job.

Old resistance, once the price closes above it, often becomes new support.
Old support, once the price closes below it, often becomes new resistance.
Like a shop's roof. If you climb above the roof, that same roof is now the floor you stand on.

S/R are zones, not exact lines

Do not treat a level as one perfect number. Treat it as a small band, or zone (a small price range).
Example: instead of exactly ₹200, think "the ₹198 to ₹202 area."
Price is messy. Give the level a little room to breathe.

🔍 Example

Say a stock, "Sunrise Ltd," trades like this:

It falls to ₹100 three times and bounces up each time. So ₹100 is support.
It rises to ₹120 twice and drops back each time. So ₹120 is resistance.

A tiny picture:

₹120 ---X---X---  <- resistance (ceiling)
       /   \  /
      /     \/
₹100 -o---o---o-  <- support (floor)

How you might use it:

Near ₹100, buyers may return, so you watch for a buy chance.
Near ₹120, sellers may return, so you watch to book profit or stay away.
Now imagine the price closes above ₹120. The flip may happen: ₹120 could become new support. If price later dips back to ₹120 and holds, that is the old ceiling acting as a floor.

Remember: this is a plan, not a promise. Levels can and do break.

⚠️ Common mistakes

Blindly trusting a bounce. A level can break. Never assume price must turn.
Drawing lines too thin. S/R is a zone. An exact single price will trap you.
Ignoring round numbers. Beginners often miss 100, 500, 1000 — but the market watches them.
Using weak levels. A level touched only once is weak. More touches means stronger.
No exit plan. Even a strong level can fail, so always know where you are wrong and will exit.

✅ Key takeaways

Support is a floor where buyers step in; resistance is a ceiling where sellers step in.
Levels form because price has memory and orders cluster there.
Broken resistance can become support, and broken support can become resistance (the flip).
Draw S/R from past swing highs and lows, and watch round numbers.
Treat S/R as zones, and never assume a bounce — levels can break.

📝 Quick check

Q: What is the difference between support and resistance? A: Support is a price floor where buyers tend to step in; resistance is a price ceiling where sellers tend to step in.
Q: A stock breaks above old resistance at ₹120. What might that level become? A: It may flip and become new support — the old ceiling can act as a new floor.
Q: Why should you treat S/R as a zone, not one exact price? A: Because price is messy and rarely stops at a perfect number, so you give the level a small range of room.
