Common Zone-Marking Mistakes
Mistake 1: marking the leg, not the base
The single most common error. The zone is the small cluster of base candles BEFORE the explosive move. The explosive move itself is the leg-out — it is NOT the zone. Shading the whole rally is meaningless for future reference.
Mistake 2: oversized zones
A zone so wide that any price in a large range 'touches' it is useless. Zones must be tight and specific. More than 5 base candles is already a warning sign; a zone spanning 10% of the price range is not a zone at all.
Mistake 3: including leg-in and leg-out in the box
Only base candles belong inside the zone rectangle. Including the approach candle (leg-in) or the departure candle (leg-out) inflates the zone and distorts the proximal and distal lines.
Mistake 4: inconsistent rules
Switching between body-to-wick and wick-to-wick mid-study makes results impossible to compare and introduces unconscious bias toward rules that 'worked' on visible outcomes.
Mistake 5: hindsight bias
Drawing zones after seeing where price reacted — 'it bounced there so it must be a zone' — is not analysis, it is storytelling. Zones must be drawn from the LEFT side of the chart (from structure alone) before price reaches them.
Practice checklist
- Shade only the base candles — never the leg-in or leg-out
- If the base is more than 5 candles or messy — skip it
- Lock one marking rule (body-to-wick or wick-to-wick) before starting
- Mark zones from the left side of the chart, not from where price reacted
Mistakes to avoid
- Drawing zones after the fact to explain a move you already saw
- Letting a zone 'drift' — adjusting it after it didn't react where you expected
