Support and resistance is the most-taught concept in technical analysis and the most poorly drawn. Most retail traders end up with a chart that looks like a barcode — dozens of lines, none of them actionable.
This is the short list of levels that actually matter on NSE intraday.
The seven references
In order of significance:
- Today’s VWAP. Institutional reference line. Every algo watches it. See VWAP strategy.
- Previous day’s high and low. Where yesterday’s session ended decisive moves.
- Today’s opening range high and low (9:15 – 9:30). See ORB strategy.
- Daily pivot levels (Pivot, R1, S1). See pivot points.
- Previous swing highs / lows on the 15-min chart (last 3 sessions).
- Round numbers. ₹500, ₹1,000, ₹2,500 — psychological levels real participants react to.
- 52-week high / low (rarely intraday-relevant but powerful when it triggers).
That’s it. Everything else is decoration.
Why fewer lines = more usable
A chart with 4 levels lets you see when price is between levels (do nothing) or at a level (alert + setup check). A chart with 14 levels means price is always “at a level”. Worthless.
Rule: maximum 4–6 levels on the chart at any time. If you draw a new one, erase an old one.
How to draw S/R on Indian intraday
Step 1: Mark the static references before the open.
- Previous day H/L.
- Round numbers near current price.
- Pivot, R1, S1 for today.
Total: 5 lines. Do this at 9:00 IST.
Step 2: Mark dynamic references during the session.
- VWAP (auto-plots).
- Opening range high/low at 9:30 IST.
Total: 2–3 additional lines. Now you have 7–8 references; remove the round number you’re furthest from.
Step 3: Recognize when a level matters.
A level matters when two or more references stack within ~0.2% of each other. Example:
- Previous day high = ₹2,520.
- R1 = ₹2,522.
- Round number = ₹2,500.
The cluster at ₹2,520–₹2,522 is now a zone, not a line — and the strongest resistance of the day.
The setups
Long at support
- Price comes down to a stacked support zone.
- Bullish candle pattern — hammer or engulfing — at the level.
- Volume > 1.3× average.
- RSI > 35 and turning up. See RSI for intraday.
- Entry: break of pattern high.
- Stop: 1 × ATR below the zone. See ATR for intraday.
Short at resistance
Mirror image. Stronger on days when index is also weak.
Breakout above resistance
- 5-min candle closes above the zone with volume > 1.5× average.
- Index alignment.
- Entry: close of breakout candle.
- Stop: back inside the zone.
- Target: next reference level above.
Failed break (fade)
The most underrated setup:
- Price breaks above resistance, fails to follow through, returns inside the level within 2 candles.
- That’s a trapped breakout — usually leads to a sharp move opposite direction.
- Entry: break of the failed-break candle low.
- Stop: above the breakout high.
Confluence multiplier
The probability of a level holding scales with how many references stack at it.
| References stacked | Treat it as |
|---|---|
| 1 | Weak — needs confirmation |
| 2 | Tradeable with normal size |
| 3 | High-confidence setup |
| 4+ | Don’t get cute — trade it |
The single best 4-stack on Indian intraday: VWAP + pivot + previous day H/L + round number, all within 0.3%.
Common mistakes
- Drawing too many lines. Past 6 references, you’re hiding signal in noise.
- Treating every wick as a “test”. Only sustained closes near a level matter.
- Ignoring stacking. A lone line is a coin flip; a 3-stack is real.
- Not redrawing levels. Yesterday’s H/L is today’s reference; the day-before-yesterday’s H/L isn’t.
- Trading against the index. A clean support hold on a stock against a falling Nifty is still bad odds.
A clean S/R setup you can take tomorrow
- Universe: Nifty 100.
- Pre-market: mark previous day H/L, R1/S1, round numbers, and 20-day high/low.
- Add VWAP and opening range at 9:30.
- Wait for price to reach a stacked zone.
- Look for a candlestick pattern + volume + RSI confirmation.
- Enter on confirmation candle; stop 1 × ATR away.
- Target: next reference above (long) or below (short).
The trade frequency drops sharply with this discipline. So does the loss rate.
FAQs
Should I use horizontal lines or zones? Zones, ~0.15% wide. Price doesn’t reverse at exact levels; it reverses inside narrow bands.
Are trendlines useful for intraday? Sometimes. They’re more subjective. Stick to horizontal references first.
Where do you find “good” levels on Indian small-caps? You usually don’t. Small-caps’ levels are spread-artefacts. Stick to large-caps.
