8. Support and resistance
If you learn only one thing from this module, learn this chapter well.
- Support is a price zone where buyers have stepped in before and stopped a fall. A floor.
- Resistance is a price zone where sellers have shown up before and stopped a rise. A ceiling.
At the Lasalgaon onion market near Nashik, suppose traders know that whenever the price falls to ₹1,500 per quintal, big exporters start buying in bulk. Farmers also hold back their stock below that price. So the price keeps bouncing from around ₹1,500.
And whenever it reaches ₹2,200, many farmers rush to sell their stored onions. So the price keeps getting pushed back from ₹2,200.
₹1,500 is support. ₹2,200 is resistance. Not because of magic – because of how people behave at those prices.
8.1 Why levels work
Levels work because of memory:
- Buyers who missed the last bounce at ₹1,500 are waiting to buy if it comes back there.
- People who bought at ₹2,200 and saw the price fall are waiting to sell at "no loss" when it returns.
- Many traders watch the same obvious levels, so their orders cluster there.
8.2 How to draw support and resistance
- Zoom out on the daily chart.
- Find areas where price turned more than once – look at wicks and closes.
- Draw a horizontal line (or better, a narrow zone) through them.
- More touches, bigger reactions, and more recent turns make a level stronger.
Price rarely turns at the exact same rupee. Think of a level as a band – for example, ₹1,490 to ₹1,510. This saves you from many false alarms.
8.3 Find the levels yourself
8.4 Role reversal – the most useful idea
When price breaks above resistance and stays there, that old resistance often becomes new support. When price breaks below support, that old floor often becomes new resistance.
Why? People who sold at ₹1,000 and watched it run up regret selling. When price comes back to ₹1,000, they buy again.
Round numbers like ₹1,000, ₹500 or Nifty’s big round levels often act as levels too, because humans love round numbers. Jab bhi chart kholo, pehle levels mark karo. Then think about patterns.
A level where buyers repeatedly stopped the fall is support.
Broken resistance often becomes support. That retest is a level many traders watch.
More touches, bigger reactions and recent turns make a level more meaningful.
- Support = floor where buyers step in. Resistance = ceiling where sellers show up.
- Levels work because of memory, regret and many traders watching the same prices.
- Draw zones through areas with multiple turns. Recent and repeated turns matter most.
- Role reversal: broken resistance becomes support, broken support becomes resistance.
- Ek line mein: Jahan price baar baar palta hai, wahi asli level hai – aur toota hua ceiling aksar naya floor ban jaata hai.
