Price Band and Circuit Limit on NSE: Upper Circuit, Lower Circuit and Index Halts Explained

Every NSE stock runs under a price band and circuit limit rule that decides how far it can move in one session. On top of that, the whole market has a second safety switch that can freeze trading in every stock at once. When you read that some small-cap “hit the upper circuit” or “got locked in the lower circuit”, this is what’s going on. Here we break down the NSE price band and circuit limit system in plain language: the 2%, 5%, 10% and 20% stock bands, why big F&O stocks carry no fixed band, how the index-based market-wide circuit breaker stops trading at 10%, 15% and 20%, what the latest NSE band file shows, and how to work out the limits yourself with simple examples.

Circuit limits matter most to traders who track daily movers, so this sits naturally next to our Stock Market Today India hub. To check what a stock actually did on a given day, our guide on how to read the NSE bhavcopy shows where the daily high, low and close get published.

What are price bands and circuit limits on NSE?

A price band is the range around the previous close inside which a stock can trade that day. The top of the range is the upper circuit, the bottom is the lower circuit. Once a stock touches either edge, trades can still go through at that price, just not beyond it, so the price is effectively capped for the rest of the session.

NSE’s price bands page lists the daily bands that apply to securities in these tiers, each “either way”, which means the same percentage up and down:

• 2% either way
• 5% either way
• 10% either way
• 20% either way on all remaining scrips, including debentures and preference shares

NSE adds that scrips with derivative products available on them have no price bands. Scrips without derivatives of their own that are part of index derivatives still have bands. The page also says the auction market uses a 20% band, and the Limited Physical Market follows the same bands as the Normal Market.

Why F&O stocks have no fixed band

Large, liquid stocks traded in the futures and options segment don’t get a fixed daily band. That doesn’t mean one order can shove them to any price. NSE says that to stop members entering orders at non-genuine prices in such securities, it has fixed an operating range of 10%. So the exchange still guards against fat-finger orders, but it lets these stocks find their price through the derivatives-linked market instead of pinning them to a hard daily cap.

A circuit limit does not stop a stock from falling; it stops it from falling today. The pressure that pinned it to the band is still there at the next open.

What the latest NSE price band file shows

NSE publishes the band for every security in a downloadable file, sec_list.csv, listing the symbol, series, security name, band and remarks. The version put out on the evening of October 16, 2026 has 3,587 rows. This is how they split by band:

A few familiar names show the tiers in action. Reliance Industries, TCS, HDFC Bank, Infosys and Polycab India are all marked “No Band”, in line with NSE’s rule for stocks with derivatives. IDBI Bank, Karur Vysya Bank, Urban Company, Bansal Wire Industries and Hindustan Composites sit in the 20% band. Right at the tight end, Aban Offshore is listed in the BE series with a 2% band.

Don’t skip the remarks column. In this file, 74 securities carry a remark naming a GSM stage, which is part of the exchange’s surveillance framework. Of those 74, 39 are in the 5% band and 9 in the 2% band, while 21 are in the 20% band and 5 in the 10% band. Tight bands and surveillance remarks often travel together, and a stock dropping into a 5% or 2% band can be a hint that the exchange is watching it more closely. If a series code like EQ, BE or SM puzzles you, check NSE’s legend of series, which we go through in the bhavcopy guide linked above.

How to calculate a stock’s upper and lower circuit

The maths is easy. Take the previous close, multiply it by the band percentage, then add or subtract the result. The examples below use hypothetical stocks and prices purely to show the method; they aren’t real quotes.

Your broker’s terminal may show slightly different numbers from a hand calculation because of rounding, so always go with the exchange or broker figure when placing orders.

Look at what the 2% band does to Stock A. Even if the company puts out terrific news, the stock can gain only ₹1 that day. If buyers keep queuing at ₹51 with hardly any sellers, the stock is “locked” at the upper circuit. Next morning a fresh band is worked out from that close, and the same thing can play out for several sessions. It runs in reverse at the lower circuit too, which is why tight-band stocks can be really hard to get out of in a falling market.

Index-based market-wide circuit breakers

Stock bands are only half the setup. NSE’s circuit breakers page describes an index-based market-wide circuit breaker that kicks in at three stages of index movement, either way: 10%, 15% and 20%. When one is triggered, trading halts in a coordinated way across all equity and equity derivative markets nationwide.

What sets it off is a move in either the BSE Sensex or the Nifty 50, whichever is breached first. NSE cites its circular 85/2013 dated October 11, 2013 for this arrangement. After a halt, the market reopens through a pre-open call auction session, the same kind of order-matching window we explain in our guide to the pre-open session on IPO listing day.

How long trading stops

How long the halt lasts depends on both the size of the move and when it happens, as laid out by NSE:

NSE works out the 10%, 15% and 20% trigger levels every day from the index’s previous closing level, rounded to the nearest tick size.

Where the index circuit would trigger: an illustration

Say, just for illustration, the Nifty 50 closed at 25,000 the day before. That’s a round hypothetical number, not a current market level.

• 10% trigger: 10% of 25,000 is 2,500 points, so the levels would be 22,500 on the way down and 27,500 on the way up.
• 15% trigger: 3,750 points, giving 21,250 and 28,750.
• 20% trigger: 5,000 points, giving 20,000 and 30,000.

Now layer on the timing rules. A 10% fall at 11:30 AM would halt trading for 45 minutes until 12:15 PM, then a 15-minute pre-open session, so normal trading would restart around 12:30 PM. The same 10% fall at 2:45 PM would trigger no halt at all. A 15% fall at 1:30 PM would mean a 45-minute halt plus the 15-minute pre-open, while a 15% fall at 2:15 PM would shut the market for the day. A 20% move ends the session whenever it comes.

The market-wide breaker is about time, not price: it buys investors a pause to absorb news before trading resumes through an auction.

How Indian circuit rules compare with the US system

India isn’t alone here. Investopedia’s circuit breaker explainer describes the US market-wide system, which is triggered by declines in the S&P 500 of 7%, 13% and 20%. A 7% or 13% drop halts trading for 15 minutes, and a 20% drop halts it for the rest of the day. The US also runs a limit up-limit down mechanism for individual stocks and exchange-traded products, which pauses trading when prices move outside set bands.

Two differences jump out. The US market-wide breaker reacts only to falls, whereas NSE’s index breaker works either way. And the US single-stock mechanism pauses trading for a few minutes, while an Indian stock that hits its band simply can’t trade past it for the rest of the day.

Why circuits matter when you’re actually trading

Liquidity can vanish at the band

A stock stuck at its lower circuit may show a long line of sell orders and barely any buyers. A stop-loss placed below the band won’t save you, because the price can’t trade there that day. If you deal in small-caps or SME stocks with tight bands, size positions so that being stuck for a few sessions wouldn’t hurt badly. Our guide to stop loss in trading covers how different order types behave when liquidity dries up.

The magnet effect

Investopedia notes a criticism called the magnet effect: as a market gets close to a halt level, traders may rush to sell before trading stops, dragging prices even nearer the trigger. Critics also say circuit breakers can get in the way of price discovery. The same thing can happen with a single stock nearing its upper or lower circuit, where traders chase the band instead of the fundamentals.

A band change tells you something

When the exchange shifts a stock into a tighter band, ask why. Read alongside surveillance remarks in the NSE file, a band change can signal that the stock’s price or volume has caught the exchange’s eye.

Five checks before you trade a circuit stock

1. Look up the stock’s current band in NSE’s price band file or your broker’s terminal.
2. Work out the upper and lower circuit from the previous close, and go with the broker’s rounded figure.
3. Check the remarks column for a surveillance stage.
4. Study the order book: a huge queue on one side and almost nothing on the other means getting out may not be easy.
5. Decide beforehand what you’ll do if the stock locks in the circuit against you for several days.

Questions traders keep asking

Can a stock hit the upper circuit and still trade?

Yes. Trades can go through at the upper circuit price as long as someone is willing to sell there. The stock just can’t trade above it that day.

Do Nifty 50 stocks have circuit limits?

Stocks with derivatives, which covers the large names we checked above, have no fixed daily band. NSE applies a 10% operating range to block orders at non-genuine prices, and the index-based market-wide circuit breaker still covers the whole market.

How often are the index circuit levels updated?

Daily. NSE calculates the 10%, 15% and 20% levels from the previous day’s index close.

Is the price band the same as the 52-week high or low?

No. The band limits a single day’s move from the previous close, while the 52-week high and low describe the trading range over the past year.

Two layers of protection, one habit

The NSE price band and circuit limit system works on two levels. Individual stocks are capped at 2%, 5%, 10% or 20% either way, and stocks with derivatives skip the fixed band but get a 10% operating range. Above all of that, the index-based breaker halts the entire market when the Sensex or Nifty 50 moves 10%, 15% or 20%, with halt lengths that depend on the time of day. Knowing a stock’s band before you trade, and having a plan for the day it locks against you, is one of the simplest risk controls an Indian trader has.
