Why the Third Touch Matters More Than the First Line
A trendline drawn on two points is a hypothesis. The third touch turns it into structure you can plan around.
Two points define a geometric line. Markets do not owe that line any respect until price returns and reacts again. In class we treat the first drawing as a working hypothesis and the third touch as the earliest moment the hypothesis earns desk time.
How we score a touch
A useful touch is a swing that approaches the line without requiring you to tilt the ruler. Wick-only grazes count less than closes that respect the line and reverse with clear follow-through on the next bar or two.
If you need to nudge the line after every new swing, you do not have structure—you have a moving average drawn by hand. Retire it and start again from cleaner anchors.
Classroom drill
Students mark two candidate lines on the same daily chart, wait for historical third touches in replay, and only then write a one-sentence plan for what would invalidate each line. The plan matters as much as the drawing.
