A trend line is a straight line drawn on a chart connecting two or more price points. In an uptrend, you connect higher lows. In a downtrend, you connect lower highs. Trend lines are one of the simplest yet most effective tools — they show you the trend direction and provide dynamic support/resistance levels to trade from.
How to Draw Trend Lines
Uptrend Line
- Find at least two significant higher lows
- Draw a straight line connecting them
- Extend the line into the future
- The more times price touches and bounces off the line, the stronger it is
Downtrend Line
- Find at least two significant lower highs
- Draw a straight line connecting them
- Price touching and rejecting from this line = selling opportunity
Trading with Trend Lines
- Buy bounces off uptrend lines with stop below the line
- Sell rejections from downtrend lines with stop above the line
- Trade breakouts: When price breaks through a well-established trend line, a significant move often follows
- 3 touches minimum: A trend line needs at least 3 touches to be considered valid. 2 points create a line; 3+ confirm it.
Common Mistakes
- Forcing trend lines to fit — if you have to bend the line, it’s not a valid trend line
- Using only wicks vs only bodies — be consistent. Most traders use wicks for accuracy.
- Drawing too many trend lines — focus on the most obvious ones that anyone can see
- Trading every touch — wait for confirmation (bullish candle at uptrend, bearish at downtrend)
Trend Line + Other Tools
Trend lines become extremely powerful when combined with:
- Support/resistance levels (horizontal + diagonal = confluence)
- Moving averages crossing the same area
- RSI divergence at a trend line touch
- Volume confirmation on bounces/breaks
