When support stops earning its line
Support and resistance lines age. A level that held twice on AUDUSD during a quiet Asian range may fail once London expands, yet traders often keep the old pencil stroke as if loyalty were a method.
Ask what the mark was for
Before you defend a horizontal line, name its job. Was it the edge of a multi-session range? A swing low that launched a clean leg? A round number that attracted stops? If you cannot answer in one sentence, the mark is decoration.
Revisit after a decisive close
When price closes through your level on the timeframe you claimed mattered, treat the line as on probation. A wick alone is not always a break; a full-bodied close with follow-through usually is. Technical analysis training at our desk spends more time on this probation habit than on drawing new lines.
Fewer lines, clearer questions
Erase marks that no longer earn attention. Your chart should raise one or two sharp questions for the next session — not a lattice of abandoned ideas. If you need a second pair of eyes on a contested level, a chart review is built for exactly that hour.
