How to Properly Draw and Use “Common Sense” Trendlines
If you have ever opened a stock chart and felt confused by zig-zag lines — you’re not alone.
When I first started studying charts, I tried drawing perfect mathematical lines. I failed. The market doesn’t move in straight geometry. It moves in waves of fear and greed.
That’s when I learned something important:
👉 Trendlines are not about perfection. They are about common sense.
In this article, I’ll show you how to use trendline trading the right way — in a practical, beginner-friendly manner suited for Indian stock market investors.
What Is a Trendline in the Stock Market?
A trendline is a simple line drawn on a price chart to show the direction of a stock’s movement.
Think of it like drawing a line under a staircase.
- If the stairs are going up → Uptrend
- If the stairs are going down → Downtrend
- If they move sideways → No clear trend
Trendlines help in:
- Identifying trend direction
- Spotting support and resistance
- Improving entry and exit timing
- Managing risk better
They are widely used in technical analysis, especially in equity investing and trading.
Why “Common Sense” Matters in Trendline Trading
Many beginners make this mistake:
❌ They force-fit a line to match their bias.
❌ They adjust the line until it “looks perfect.”
❌ They ignore overall market structure.
But the stock market doesn’t reward ego.
It rewards discipline and logic.
Common sense trendline trading means:
✔ Draw lines where price clearly respects a level
✔ Don’t use too many touchpoints
✔ Focus on obvious patterns
If you need to explain your trendline for 10 minutes — it’s probably wrong.
Step-by-Step: How to Draw a Proper Trendline
Step 1: Identify the Trend First
Before drawing anything, ask:
- Is the stock making higher highs and higher lows? (Uptrend)
- Is it making lower highs and lower lows? (Downtrend)?
Example:
Suppose a stock moves from ₹100 → ₹120 → ₹110 → ₹140 → ₹130.
It is forming higher highs and higher lows.
That’s an uptrend.
Step 2: Connect At Least Two Clear Swing Points
For an uptrend:
- Connect two or more higher lows.
For a downtrend:
- Connect two or more lower highs.
Important rule:
The more times price touches the line and respects it, the stronger the trendline.
Step 3: Do Not Force the Line
In real markets:
- Some candles will slightly pierce the line.
- Minor breaches are normal.
Use zone thinking, not laser precision.
Think of it as a “support area,” not a surgical cut.
Real Indian Example (Educational Case Study)
Let’s say a Nifty 50 stock rises from ₹500 to ₹650 over 4 months.
Each time it falls, it stops near:
- ₹520
- ₹560
- ₹600
If you connect these lows, you get a rising support line.
Now suppose price breaks below ₹600 with strong volume.
That may signal:
- Trendline breakdown
- Momentum shift
- Higher risk
A disciplined investor may:
- Reduce exposure
- Trail stop-loss
- Wait for confirmation
This is how trendline trading becomes a risk management tool, not a prediction tool.
Behavioral Finance: Why Trendlines Work
Trendlines work because humans repeat patterns.
Markets reflect:
- Fear
- Greed
- Herd mentality
- Anchoring bias
When many traders see the same support line, they place buy orders there.
This creates:
Demand cluster → Price bounce
That’s behavioral finance in action.
How to Use Trendlines in Investing (Not Just Trading)
Many people think trendlines are only for day traders.
Wrong.
Even long-term investors can use them for:
- Better SIP timing
- Avoiding panic selling
- Identifying structural trend changes
Example:
If you are investing ₹10,000 monthly in an equity mutual fund or stock, and the broader market breaks a long-term trendline, you may:
- Stay invested (if long-term)
- But avoid lump-sum deployment
- Maintain asset allocation discipline
Trendlines support smarter financial planning, not speculation.
Common Mistakes in Trendline Trading
Here are mistakes I often see beginners make:
1. Drawing on Every Timeframe
Daily, hourly, 5-minute — confusion guaranteed.
Start with:
- Weekly chart (big picture)
- Then daily chart
2. Ignoring Volume
A trendline break with low volume is weak.
High volume break is stronger.
3. Using It Alone
Never rely only on trendlines.
Combine with:
- Moving averages
- RSI
- Market structure
- Risk management rules
Simple Framework: The 4R Rule
To simplify trendline trading, remember 4R:
- Recognize the trend
- Respect obvious swing points
- Risk-manage every trade
- Review when price breaks structure
This keeps emotions under control.
Cultural Insight: Why Indians Love Trendlines
In India, we value jugaad and practicality.
Trendlines are not about complex formulas.
They are about observing patterns.
Just like:
- A shopkeeper senses customer demand
- A farmer observes seasonal patterns
Investors observe price behavior.
Trendline trading is structured common sense.

Final Thoughts
Trendlines are simple.
But simplicity is powerful.
They won’t make you rich overnight.
They won’t predict the future.
But they will:
- Improve discipline
- Strengthen risk management
- Enhance your investing decisions
If you want to grow wealth sustainably in the stock market, focus on process — not prediction.
Learn. Practice. Manage risk.
That’s real financial wisdom.
