Support and resistance are the foundation of almost every trading approach. They tell you where price has turned before, where buyers and sellers are likely to act again, and where to place your entries, stop-losses and targets.

This guide explains how to find support and resistance on NIFTY, BANKNIFTY and SENSEX, how to confirm them, and how to use automatic detection on the OPIFY spot chart.

Where support and resistance come from

• Previous swing highs and lows: where price turned before.
• Previous day's high, low and close.
• Opening range: the high and low of the first 15–30 minutes.
• Round numbers: NIFTY levels like 25,000 or 25,500.
• Option open interest: strikes with heavy put OI (support) and call OI (resistance).

How to draw levels by hand

1. Start on a higher timeframe, such as 1-hour or daily, and mark the most obvious turning points.
2. Switch to 15-minute and add the previous day's high and low.
3. Add the opening range on the current day.
4. Keep only the 3–5 most important levels. Too many lines create confusion.

Automatic support and resistance detection

Drawing levels manually takes time, and it's easy to be biased toward the levels you want to see. The OPIFY spot chart includes SR Detection, which marks support and resistance zones on the chart automatically.

The AI Trend Insight feature goes further: it analyses recent candles and returns the current trend (bullish, bearish or neutral), support and resistance levels, chart patterns and an outlook. You can set alerts on support breakouts, resistance breakouts or a custom level.

How traders use the levels

Bounce trades

Price pulls back to support and shows a rejection candle. Entry near support, stop-loss just below it.

Breakout trades

Price closes strongly above resistance. Many traders wait for a retest of the broken level, which often turns into support.

Targets

The next resistance above (for longs) or next support below (for shorts) is a natural target.

Stop-loss placement

Place stops beyond the zone, not inside it, so normal noise doesn't hit them.

Confirm with option data

Price-based levels are stronger when option data agrees:

• Check the OI chart. Is there heavy put OI near your support or call OI near your resistance?
• Look at the PCR chart to see overall sentiment.

Practise on past days

Use Bar Replay on the spot chart. Mark levels using only the first hour, then step through the day and see which levels held.

Common mistakes

• Drawing too many levels.
• Expecting levels to hold forever. Each test weakens them.
• Entering a breakout without confirmation.
• Ignoring the bigger trend.

Frequently asked questions

Which timeframe is best for support and resistance?

Find major levels on higher timeframes (1-hour, daily) and fine-tune them on 5–15 minute charts.

Can I get alerts when a level breaks?

Yes. The spot chart supports alerts on support breakout, resistance breakout or a custom level.
