Trendline Tutorial: Rules, Examples & Trading Strategy Explained

1) What is a Trendline

A trendline is a straight line that connects key price points (highs or lows) to show direction. It is used to identify:

• Trend direction (uptrend / downtrend)
• Dynamic support & resistance
• Potential breakout points

---

2) Types of Trendlines

➤ Uptrend (Bullish Trendline)

• Connect higher lows
• Line acts as support
• Price tends to bounce from it

---

➤ Downtrend (Bearish Trendline)

• Connect lower highs
• Line acts as resistance
• Price tends to fall after touching it

---

➤ Sideways (Range Trendline)

• Horizontal lines
• Acts as support & resistance zones

---

3) Exact Rules to Draw a Trendline (Most people get this wrong)

Rule 1: Minimum 2 points, 3rd confirms

• 2 points = line
• 3rd touch = valid trendline

Rule 2: Use WICKS, not just bodies

• Always consider full candle range (high/low)

Rule 3: Don’t force the line

• If you need to adjust too much → you're wrong

Rule 4: Avoid steep angles

• Too steep = unsustainable → will break easily

Rule 5: More touches = stronger line

• 4–5 touches = high reliability

---

4) Step-by-Step: How to Draw (Practical)

Step 1: Identify trend

• Uptrend → higher highs + higher lows
• Downtrend → lower highs + lower lows

Step 2: Pick anchor points

• Uptrend → connect lows
• Downtrend → connect highs

Step 3: Extend the line

• Extend into future to predict reactions

Step 4: Validate

• At least 3 touches without break

6) Breakout Strategy (Where money is made)

Trendline Break = Opportunity

Entry logic:

• Wait for breakout
• Wait for retest
• Enter after confirmation candle

Avoid this mistake:

• Entering immediately on breakout = risky

---

7) Advanced Concepts (Most beginners ignore)

1. Trendline Flip

• Support becomes resistance (and vice versa)

2. Multiple Trendlines

• Use inner + outer trendlines for precision

3. Confluence = Strong setup

Combine with:

• Support/resistance
• Moving averages
• Volume

---

8) Brutal Truth (Important)

• Trendlines are subjective
• Two traders can draw differently
• Alone, they are not enough to trade

If you're relying only on trendlines → you will lose money.
