Zones instead of hairlines
Why noisy markets punish single-price lines — and how to decide the width of a support or resistance zone.
Hairline prices look precise on a screenshot. In liquid equities and FX pairs, the tape often brushes both sides of a “perfect” line without respecting it. We teach zones first: a band that covers the cluster of prior reactions.
A practical width starts from the range of the candles that formed the original reaction. If three sessions wicked into the same area, the zone spans those wicks. Tighten only when the market’s average true range is small relative to your timeframe.
In the Support & Resistance Intensive, Session 2 is devoted to converting students’ hairlines into zones without turning the chart into a fog bank. The goal is fewer objects, each with a clear reason to exist.
