Demand & Supply Zones for NSE Nifty 500
A free, educational scanner that automatically detects fresh demand and supply zones across Daily, Weekly, Monthly, Quarterly and intraday (15m / 75m) timeframes — graded, charted, and refreshed every trading day.

Every price chart hides a simple story: at certain areas, buyers have historically overwhelmed sellers, and at others, sellers have overwhelmed buyers. Those areas are called demand zones and supply zones. NVXSCAN scans the entire NSE Nifty 500 every trading day, finds these zones automatically, scores them for strength, and draws them on an interactive chart — so you can study the market’s structure without marking up hundreds of charts by hand.
Everything below explains what those zones are, how they form, and how NVXSCAN presents them. It is a learning tool: nothing here is a buy or sell recommendation.
Demand Zone DEMAND · GREEN
A demand zone is a price area where buying interest has previously overwhelmed selling — a region where buyers stepped in with enough force to halt a fall and push price sharply higher. On the chart it shows up as a small, tight base (a brief pause or consolidation) that price then left in a strong upward move.
Why does such a pocket of buying exist? These bases often mark where large, patient participants — the kind loosely called “institutional” — accumulated positions. Because a big buyer cannot fill an entire order at a single price without moving the market against themselves, they leave behind a pool of unfilled demand. When price later returns to that area, the leftover buying interest can absorb selling and turn price back up.
For a student of the market, a fresh demand zone is therefore read as a potential support area — a place where interest to go long has appeared before. It marks a region worth watching and understanding, never a signal to act.
- Balance of power: buyers overwhelm sellers in this area.
- Origin: concentrated / institutional buying (accumulation).
- Shape: a base, followed by a strong rally away from it.
- Read as: a support / long-interest area.
- Strongest when fresh — before price has returned to test it.
Supply Zone SUPPLY · RED
A supply zone is the mirror image: a price area where selling interest has previously overwhelmed buying — a region where sellers stepped in hard enough to stop an advance and drive price sharply lower. It appears as a base that price left in a strong downward move.
These pockets typically form through distribution — large holders booking profits or unloading positions into strength. Just as with demand, a big seller cannot complete their order at one price, so they leave behind a pool of unfilled supply. When price climbs back into that area, the leftover selling can cap the move and push price down again.
A fresh supply zone is therefore read as a potential resistance area — a place where interest to sell / go short has appeared before. Again, this is context for study, not a trade instruction.
- Balance of power: sellers overwhelm buyers in this area.
- Origin: distribution / profit-booking by large holders.
- Shape: a base, followed by a strong drop away from it.
- Read as: a resistance / short-interest area.
- Strongest when fresh — before price has returned to test it.
Zone Patterns — DBR, RBR, RBD, DBD
Every zone is built from a base with a strong leg on each side. The two legs decide whether the base becomes a demand zone or a supply zone, and give the pattern its three-letter name.
Price drops into a base, pauses, then rallies strongly away. The buyers who reversed the drop leave demand behind.
Price rallies, pauses in a base, then rallies again — a demand zone that forms inside an existing up-move (continuation).
Price rallies into a base, pauses, then drops strongly away. The sellers who reversed the rally leave supply behind.
Price drops, pauses in a base, then drops again — a supply zone that forms inside an existing down-move (continuation).
Timeframes
The same zone logic is applied across several timeframes, from long-term positional down to intraday. The timeframe you choose should match your trading style.
Swing & positional
Daily, Weekly, Monthly, Quarterly. Bigger, slower-moving zones suited to holding positions for several days, weeks or months. Higher timeframes produce fewer zones, but each one generally carries more weight.
Intraday
15-minute and 75-minute. Finer zones for same-day or very short-term study. They appear far more often and are more precise, but they are also shorter-lived than the higher-timeframe zones.
The chart’s technical indicators
Each interactive chart draws the demand/supply zone boxes together with four classic indicators, so you can read a zone in the context of momentum and trend.
RSI (14)
The Relative Strength Index over a 14-period lookback — a momentum oscillator. High readings suggest momentum is stretched to the upside (overbought); low readings, to the downside (oversold). Level lines frame the signal bands (80/40 for a bullish read, 60/20 for a bearish one).
EMA (20)
The 20-period Exponential Moving Average weights recent prices more heavily, so it reacts quickly to the latest move — a fast read on the short-term trend.
SMA (50)
The 50-period Simple Moving Average is the plain average of the last 50 closes. It smooths out the noise and shows the medium-term trend direction.
Volume
Volume is how much traded during each candle — a read on the participation and conviction behind a move. Strong moves out of a base on higher volume are more meaningful.
Quality Grades
Not every zone is equal. NVXSCAN scores each zone from 0–100 for its overall strength and translates that into a simple letter grade, so the cleanest setups stand out at a glance.
Think of the grade as a first filter for your attention: start with A+ and A zones, and treat B and C as lower-conviction context. (The exact scoring recipe is intentionally kept under the hood.)
Only fresh zones
NVXSCAN deliberately surfaces only fresh zones — areas that price has not yet returned to since the zone formed. The reasoning is simple: the first time price revisits a zone, much of the leftover demand or supply can be consumed. Once a zone has been tested, NVXSCAN stops showing it, so the dashboard always stays focused on untested areas rather than cluttering the chart with old, spent levels.
Three scanner types
The dashboard groups zones by how much surrounding context each scan layers in. Pick the view that matches how you like to trade.
Single timeframe
A pure fresh-zone scan on one swing timeframe (Daily, Weekly, Monthly or Quarterly), on its own. The clean, direct view of demand & supply.
Higher-timeframe context
Adds higher-timeframe confluence — a higher timeframe together with intraday (15m / 75m) — so a zone is seen against the bigger-picture zones around it.
Context + trend
Layers a higher → intermediate → lower timeframe pipeline together with curve-location and a trend read, for the most context-rich view of a zone.
Result Check — a permanent accuracy record
The scanner only ever shows fresh zones — the moment price tests a zone it disappears, so its outcome is never recorded anywhere. Result Check fixes that: every zone NVXSCAN has ever found is kept forever in a permanent ledger and then followed forward, candle by candle, to see how it actually resolved.
Honest outcomes
Each past zone is walked forward from the day it formed: did price reach the target (WIN), hit the stop (LOSS), or is the trade still running (OPEN)? Zones price never entered are simply dropped — only real outcomes are counted.
Where the edge is
Win rate and average / min / max holding days are broken down for each scanner (Simple, HTF, HTF & Trend) and each quality grade (A+/A/B/C), kept strictly separate so you can see which setups actually held up.
Nothing hidden
The ledger is append-only and never wiped, so the accuracy history builds up openly over time. It is educational only — it shows how past zones resolved, never money or P&L, and past accuracy never guarantees future results.
