Case note: From round numbers to confluence zones
Participant: Corporate group from a Bangkok logistics firm, four attendees, November 2025 private half-day.
Starting point: All four marked horizontal lines at round numbers (100, 105, 110) on the same SET stock without referencing weekly swings.
Session work: Prasert led a group mapping exercise on printed weekly charts. Two round-number lines were removed; three new zones appeared at prior swing lows invisible on the daily alone.
Outcome: Follow-up call four weeks later: participants reported using the checklist on twelve setups, validating four, skipping eight. No performance claims—only process adherence.
