Three tests for a usable trendline
A trendline earns its place when it can survive three simple tests. First, the anchors must be clear swing points that other readers would pick without coaching. Second, the line needs enough touches or reactions to matter without forcing every candle to kiss it. Third, you need a written invalidation: the candle close or structure break that retires the line.
In our Cullya studio sessions we ask participants to annotate those three answers on the chart itself. The habit slows impulsive redraws and makes post-session reviews faster. If a line fails two of the three tests, leave it off the plan until the structure clarifies.
Trendline work is not about predicting every tick. It is about stating, in plain language, what would keep you engaged and what would send you to the sidelines.
