Introduction To Trend Lines How to Use Trendline 
A trend-line is a straight line that connects two or more price points and then extends into the future to act as a line of support or resistance. In technical analysis, trend-lines are used to visually represent and identify the direction of an asset’s price over a specific period. Trend-lines can be upward (bullish), downward (bearish), or sideways (neutral).

Types Of Trend-lines

  • Uptrend Line: Drawn along the low points when the market is rising. It acts as a support line, meaning that as long as the price remains above this line, the market is considered to be in an uptrend.
  • Downtrend Line: Drawn along the high points when the market is declining. It acts as a resistance line. If the price remains below this line, it indicates a downtrend.
  • Sideways Trend Line: Indicates a market in consolidation. It’s usually characterized by a horizontal trend-line.

Importance Of Trend-lines

  • Direction Indicator: Trend-lines help in identifying the overall direction of the market, whether it’s an uptrend, downtrend, or sideways trend.
  • Support and Resistance: They act as dynamic levels of support and resistance. Prices often respect these trend-lines, making them crucial for entry and exit points.
  • Breakouts and Reversals: A breach of a trend-line often signals a potential reversal or continuation of the trend. Recognizing these breakouts can lead to profitable trading opportunities.

Limitations Of Trend-lines

  • Subjectivity: Different traders might interpret trend-lines differently. What seems like a valid trend-line to one trader might not be the same for another.
  • False Breakouts: Prices might breach a trend-line temporarily, tricking traders into thinking a breakout or reversal has occurred.
  • Not Foolproof: Like all tools in technical analysis, trend-lines are not 100% accurate and should be used in conjunction with other tools and methods.

How To Correctly Draw Trend-lines

The accuracy of a trend-line largely depends on the selection of the starting and ending points. These points, often referred to as “pivot points”, are significant highs (peaks) or lows (troughs) on a chart. Identifying these points correctly is crucial for drawing a valid trend-line.

  1. Identify the Trend:
  2. Before drawing a trend-line, determine the direction of the trend. Is it an uptrend, downtrend, or sideways trend?

  3. Choose Significant Points:
    • For an uptrend, select at least two recent lows and draw a line connecting them. The line should ideally be below the price, acting as a support.
    • For a downtrend, select at least two recent highs and connect them. This line should be above the price, acting as a resistance.
  4. Extend the Line:
  5. Once you’ve connected the initial points, extend the trend-line out into the future. This extended line will serve as a potential future line of support (in an uptrend) or resistance (in a downtrend).

  6. Adjust for Best Fit:
  7. Sometimes, especially in volatile markets, prices might not touch the trend-line perfectly. In such cases, it’s acceptable to adjust the trend-line for the best fit. This means that the line might not touch every single high or low but captures the essence of the price movement.


Drawing trend-lines is as much an art as it is a science. While the basic principles are straightforward, the nuances come with experience. It’s essential to practice drawing trend-lines across various time frames and market conditions to get a feel for their reliability and significance. Remember, no single tool should be used in isolation; combining trend-lines with other technical analysis methods can offer a more comprehensive view of the market.
