Trendline Analysis Guide

The Dynamic Floor of Price Action

A Trendline is a simple yet powerful diagnostic tool used to visualize the dominant direction and slope of an asset's price movement. Unlike horizontal support or resistance lines that maintain a static price point, trendlines move dynamically with the price, acting as a "sloped floor" (uptrend) or "sloped ceiling" (downtrend) that tracks the market's momentum over a specific interval.

• Uptrend Line: Connects a series of rising Higher Lows (HL) pivots. It acts as a dynamic support, where buyers tend to step back in.
• Downtrend Line: Connects a series of falling Lower Highs (LH) pivots. It acts as a dynamic ceiling, where sellers tend to dump supply.

The "Two-Point" Validation Rule

A common beginner mistake is drawing a trendline through every single wiggle on the chart. To be structurally significant, a trendline must adhere to strict validation logic:

• The Two-Point Rule: You must connect at least two distinct pivot points to establish a line. However, a trendline only gains true analytical validity once it is successfully "touched" or tested for a third time.
• The "Wick vs. Body" Debate: You can draw your trendlines using either the candle wick extremes (the absolute highs/lows) or the candle real body closings. Professional traders often prefer wick-to-wick because it captures the true total volatility extreme of the market psychology.

Detecting Trend Speed

Trendlines are not static; they change slope as the velocity of the trend changes. If an uptrend accelerates, you can draw a steeper line underneath the new steeper price angle—this creates a "Fan" of trendlines. When the price breaks below the steepest line, it doesn't necessarily mean the trend is dead; it may just be reverting to a slower, more sustainable trendline angle.
