What Are Support and Resistance Levels?
Support is the zone where falling price historically meets buying interest; resistance is where rising price meets selling pressure. They are approximate zones rather than exact lines and can swap roles once broken.
How are levels identified?
The most common method is marking previous reaction highs and lows on the same timeframe. Touch count, volume traded in the zone and the age of the level affect reliability. A zone on the daily chart may not appear on the 15-minute chart.
How is a breakout confirmed?
Counting a single wick as a breakout usually produces early decisions. A close beyond the level, volume support and a subsequent retest are stronger evidence.
- Confirm breakouts with a close plus volume.
- A retest is additional evidence of role reversal.
- Check liquidity and spread against fake breakouts.
Role reversal: support becomes resistance
Broken resistance can act as support on the next decline, and broken support as resistance on the next rally. That alone is not a trade reason; it must be read with volume, momentum and market direction.
- Watch whether the level holds on the first pullback.
- Evaluate role reversal within timeframe context.
- Write the invalidation (stop) in advance.
Checklist
- Which timeframe produced the level?
- How many prior reactions occurred at the zone?
- Was the breakout confirmed with a close and volume?
- Was the stop level defined in advance?
