Support is an area where demand has previously slowed a decline; resistance is an area where supply has slowed a rise. Treat them as zones rather than exact prices and judge them by recency, number of reactions, volume and higher-time-frame context.
Key points
- Mark zones, not single-paise lines.
- Fresh levels are often more informative than over-tested levels.
- Broken resistance can become support and vice versa.
- A close beyond a level is stronger than a brief intraday spike.
How to mark zones
Look for clusters of turning points, gaps, consolidation edges and high-volume reactions. Start on weekly and daily charts before moving lower.
Strength of a level
A level gains relevance from clear reactions, high participation and visibility across time frames. Repeated tests can also consume available demand or supply.
Role reversal
When resistance breaks and later holds as support, the market may be accepting a higher value area. The opposite applies after support fails.
Invalidation
A level is invalid when price accepts beyond it, not merely when a wick touches through. Define in advance whether invalidation is based on close, percentage or structure.
Worked Indian-market example
A stock repeatedly fails between ₹980 and ₹1,000. After a high-volume weekly close above ₹1,000, it pulls back to ₹990 and holds. The former resistance zone is now being tested as support.
Quick reference
| Concept | What it shows | Practical meaning |
|---|---|---|
| Horizontal zone | Repeated reactions near one area | Common and easy to observe |
| Gap zone | Untraded or lightly traded area | Can attract future reaction |
| Previous high/low | Visible swing point | Often watched by many participants |
| Round number | Psychological reference | Needs confirmation |
Risks and limitations
- Exact levels create unnecessary stop-outs.
- Over-tested zones can weaken.
- News can cause price to gap through a level.
- Analysts can mark different zones on the same chart.
Frequently asked questions
How wide should a zone be?
Use recent volatility and candle structure; there is no fixed width.
Is more testing always better?
No. Repeated tests may confirm relevance but can also weaken the level.
Can support become resistance?
Yes, after a breakdown and failed reclaim.
Should stops be exactly below support?
Stops should reflect invalidation and volatility, not only a visible line.
