Check out the new article: Price Action Analysis Toolkit Development (Part 60): Objective Swing-Based Trendlines for Structural Analysis.
We present a rule-based approach to trendlines that avoids indicator pivots and uses ordered swings derived from raw prices. The article walks through swing detection, size qualification via ATR or fixed thresholds, and validation of ascending and descending structures, then implements these rules in MQL5 with non-repainting drawing and selective output. You get a clear, repeatable way to track structural support and resistance that holds up across market conditions.
Trendlines as Structural References
In this framework, trendlines are treated strictly as structural reference points rather than predictive tools. A meaningful trendline is not defined by how easily it can be drawn, but by how consistently price interacts with it. When price repeatedly respects a slanted boundary, that boundary becomes an active and dynamic form of support or resistance, adapting naturally as time progresses. This approach is particularly relevant in trending or compressing markets, where structure is often expressed diagonally rather than horizontally.
The following diagram illustrates how trendlines are derived from ordered swing highs and lows. Ascending swing lows define support, while descending swing highs define resistance, allowing structure to guide trendline formation.
While horizontal levels remain valuable, they do not always capture the full picture. Many market phases unfold along angled or slanted structures, yet such trendlines are often difficult to draw objectively and are frequently applied subjectively. This tool is designed to make working with slanted trendlines more objective, consistent, and repeatable, allowing them to be integrated more reliably into the analysis process.
