Trend lines are diagonal lines drawn on price charts connecting swing highs or swing lows to visually represent the direction and speed of price movement. As upper indicators drawn directly on price, trend lines provide dynamic support in uptrends and resistance in downtrends, adapting to the market’s changing pace unlike static horizontal levels. For option traders, trend lines offer precise entry points when price pulls back to test them and clear warning signals when trends break, making them essential for timing premium sales and managing risk. Understanding how to draw, validate, and trade trend lines transforms chaotic price action into organized, tradeable patterns with defined boundaries.
Drawing Valid Trend Lines
Proper construction is critical:
Uptrend Lines
Connect two or more swing lows:
- Start from significant low
- Connect to next higher low
- Extend into future
- Acts as rising support
Each touch validates strength.
Downtrend Lines
Connect two or more swing highs:
- Start from significant high
- Connect to next lower high
- Extend into future
- Acts as falling resistance
The more touches, the more significant.
Technical Rules
Two Points: Minimum to draw Three Points: Confirms validity Four+ Points: Major trend line
Wicks vs Bodies:
- Bodies more reliable
- Wicks show extremes
- Use zone approach
- Allow minor pierces
Types of Trend Lines
Different applications for different lines:
Primary Trend Lines
- Connect major swing points
- Define long-term trend
- Months/years duration
- Rarely touched
Breaking these signals major change.
Secondary Trend Lines
- Connect intermediate swings
- Define medium-term trend
- Weeks/months duration
- Regular touches
Most useful for option traders.
Minor Trend Lines
- Connect short-term swings
- Define immediate trend
- Days/weeks duration
- Frequent touches
Good for timing entries.
