How to read price levels
Every symbol on Nifty Trendz carries five (or seven, on the stock chart) price levels derived from Put and Call option positioning near the current expiry. They act as reference zones — support underneath, resistance overhead — around which price tends to react.
The core ladder
Highest price at top, lowest at bottom — matches the order shown on every chart and table.
The strongest resistance zone from Call option positioning. A decisive close above it often reads as bullish continuation rather than a reversal at the ceiling.
An intermediate resistance below Call High — usually the first hurdle price meets on the way up.
The balance point between combined Put and Call positioning. Price often oscillates around this level when the trend is undecided.
An intermediate support above Put Low — usually the first cushion price meets on the way down.
The strongest support zone from Put option positioning. A decisive close below it often reads as bearish continuation rather than a bounce at the floor.
Extended levels (stock chart only)
Finer reference points inside the main range — shown as a separate group below the core ladder.
A secondary support inside the main range, between Put Low and Put/Call Int. Shown only on the stock chart, not in scan alerts or the quadrant view.
A secondary resistance inside the main range, between Put/Call Int and Call High. Shown only on the stock chart, not in scan alerts or the quadrant view.
Reading the numbers
Each level shows a price, a ₹ distance, and a percentage — how far the current close sits from that level: (Close − Level) / Close.
Negative % → the level is still ahead, overhead (resistance). Positive % → the level is already beneath price (support).
Whichever level has the smallest percentage right now — closest to 0% either way — is highlighted as the Closest Level, the zone price is currently sitting on or reacting to.
Level quality depends on open interest
- More OI, more accurate. Levels come from where Put and Call open interest is concentrated at specific strikes for the current expiry. The more Call and Put OI sitting behind a level, the more capital and positioning is actually defending that zone — and the more likely it is to matter. A level built on thin OI is more of a mathematical artifact than a real wall of positioning.
- Levels move daily. Open interest changes every trading day — new positions get added, existing ones get rolled or closed — both at the strike level and in aggregate for that stock's expiry. Because levels are recalculated from current OI, the same level can sit at a meaningfully different price today than it did yesterday, especially as expiry approaches.
- Be cautious on low-OI stocks. For symbols with thin overall open interest, treat the levels as indicative at best — expect more day-to-day noise and less reliable reactions at the printed price. Check the Call OI / Put OI figures on the stock page before leaning on a low-liquidity symbol's levels.
Using levels for trading
- Support / resistance. Treat Put levels as potential floors and Call levels as potential ceilings for the current expiry. Put/Call Int is the middle ground — where price often chops when there's no clear trend.
- Breakout / breakdown. A strong close through Call High or Put Low — not just a brief touch — is often read as a continuation signal rather than a level that will hold. Weigh this more heavily when the level was backed by meaningful OI in the first place; a break of a thin-OI level is less informative.
- Range-bound setups. Between Put Int and Call Int, some traders look to fade moves back toward Put/Call Int rather than chase a breakout.
- Timing with Scan Alerts. The levels above are static reference points for the day; Scan Alerts are the trigger — a ▲ Buy Above or ▼ Sell Below badge fires the moment price actually crosses a level intraday, on real quote data.
- Check, don't assume. Not every level behaves the same way — some act as launchpads (price keeps moving away, a continuation), others as magnets that pull price back (a reversion), and which one depends on the level, the symbol, and market conditions at the time. The Performance page reports both a continuation rate and a reversion rate — by level and by symbol — computed only from alerts whose expiry has actually passed. Check it before assuming either.
Index vs. stock levels, and what's free
Levels are grouped the same way plans are: Index (Nifty, Bank Nifty and the other index underlyings) and Stocks (everything else). The free plan still shows levels — just for data older than a few days — while a paid plan for the relevant group shows them live, the moment they're computed. See Plans for details.
