Market Timings and Settlement, Explained

A trade is matched in a moment, but your shares arrive on a later day. So every trade runs on two clocks. The first is the clock of one trading day, which decides the price. The second is a calendar of working days, which decides when shares and money actually move. This lesson keeps the two apart, because mixing them up is the most common beginner confusion.

Think of booking a train ticket. The fare is fixed when you book, and the journey happens on a later day. The comparison has a limit: a ticket is for one seat, while exchange trades are netted together, and the exchange, not you, picks the settlement day. Keep the idea of a price fixed now and a delivery that follows later.

Asha buys 10 shares at ₹200.00 from Ravi on Thursday 1 October 2026. The trade is 10 × ₹200.00 = ₹2,000, and that price is fixed on Thursday. Sabzi Wala Foods Ltd, the company in this example, is imaginary, so the price and quantity are illustrative. The dates, however, are real dates from the exchange calendars.

Friday 2 October is a trading holiday, and Saturday and Sunday are weekends. So shares and money move on Monday 5 October 2026. Her app showed Executed on Thursday, but Executed means matched, not delivered. Until Monday, Asha's shares are not in her demat account, even though the price is already final.

The rest of this lesson answers three questions. When is the price set? When do the shares arrive? What happens if something fails? We take the trading day first, then the closing price, then settlement on a calendar, and finally holidays and special days, where the calendar departs from the usual week.

A trading day has four parts: a pre-open auction, continuous trading, a closing step and a post-close window. The exchange publishes the times by circular. The table below shows them for the equity cash segment on NSE and BSE as notified in 2026. Treat it as a map of the day, and confirm the current times on nseindia.com and bseindia.com.

Picture a sabzi mandi day. An early auction fixes the first rate, open trading follows, and a closing round ends the day. Mandi hours are custom, handed down by habit. Here the times are different in kind, because SEBI and the exchanges set them, publish them, and revise them by written notice when they decide to.

These times have changed more than once in about a year. Block deal rules changed in October 2025. The closing auction began on 3 August 2026, and a revised pre-open applies from 7 September 2026. So a timing remembered from an older article may be out of date, which is why every timing in this lesson carries its date.

Which clock a share follows at the close depends on the share. Shares with futures and options end continuous trading at 3:15 pm and move to a closing auction, while other shares trade until 3:30 pm. So the market does not close at 3:30 pm for every share, and the notice for the day is the final word.

Futures and options trade until 3:40 pm, and block deals have their own windows, which section 6 covers. A special day, such as Muhurat or a Sunday Budget session, is announced separately. The post-close window from 3:50 to 4:00 pm applies to both groups of shares, and in it orders can be placed only at the closing price.

Before 9:15 am the exchange collects orders for about ten minutes and matches them once, at one price. The times below apply from 7 September 2026; check nseindia.com and bseindia.com for the current schedule. Entry runs from 9:00 am, matching happens from 9:10 to 9:12 am, and a short buffer follows before continuous trading begins.

Picture the mandi's early auction. Each side writes a rate and a quantity. One rate is picked, and then free trading starts. Here a fixed rule picks the rate, and orders are anonymous, so nobody knows who is on the other side. The comparison stops there, because an exchange auction matches many buyers and sellers at once.

The lesson on how an exchange works shows how the price is found. We reuse its ₹201, with the previous close at ₹200.00. Asha's limit order buys 10 shares at up to ₹203. She pays 10 × ₹201 = ₹2,010, not 10 × ₹203 = ₹2,030, because every matched order trades at the one opening price.

Ravi's limit sell at ₹199 works the same way. He receives 10 × ₹201 = ₹2,010, not 10 × ₹199 = ₹1,990. Both sides get a better price than the limit they set. A limit is the worst price a person accepts, and it is not the price that is paid.

A limit order with no match moves into continuous trading at its limit price. It keeps its original time stamp, which is the time the order was entered. Entering at 9:00 sharp earns no better price, because all matched orders trade at one price. A market order entered after 9:05 am is rejected, as only limit orders are accepted then.

After the opening auction, an order can match at any moment from 9:15 am. The best price goes first, and at the same price the earlier order goes first. An exchange order book is anonymous, and the rule for who goes first is fixed, so the order of matching does not depend on who the trader is.

This is the open mandi after the early auction. A deal happens whenever a buyer and a seller agree on a rate. The difference is scale and order: thousands of buyers and sellers sit in one book, and the rule of best price first, earlier order first, decides which two meet.

A day order is valid for the trading day and ends with it. An IOC (immediate or cancel) order fills what it can at once and cancels the rest. Some apps offer longer instructions held by the broker, and those follow the broker's own rule. An order does not stay until you cancel it, so a day order never carries over by itself.

Take a share with a closing auction, where the reference price is ₹200.00, the average of trades from 3:00 to 3:15 pm. The closing band is ±3%: 200 × 0.03 = ₹6, so ₹194.00 to ₹206.00. Asha's day limit buy of 10 at ₹198.00 sits inside that band, so it can be carried forward.

The price never comes down to ₹198.00, so nothing trades. In a share with a closing auction, the order is carried into it, because ₹198.00 is inside the band. Without one, it expires at the end of the day. A limit at ₹190.00 is outside the band, so it would not be carried in.

Shares with futures and options get their close from a closing auction, held 3:15 to 3:35 pm. Other shares get the average of the last half-hour. This began on 3 August 2026, in a first phase. The close feeds index values, mutual fund NAV (the value of one fund unit) and derivatives settlement, so it matters far beyond one day's chart.

Think of a class result set by one final exam, or by an average of recent tests. Either way the result comes from real work, not from a guess. In the same way both methods of closing use real trades and orders. The close is not the last price you saw at 3:29 pm, and it does not tell you where the next day opens.

Take a share with no closing auction. Its last half-hour trades are 1,000 at ₹500.00, 2,000 at ₹502.00, 500 at ₹498.00 and 1,500 at ₹501.00. That is 5,000 shares for ₹5,00,000 + ₹10,04,000 + ₹2,49,000 + ₹7,51,500 = ₹25,04,500. Each trade counts in proportion to the shares it moved, so large trades weigh more.

The average is ₹25,04,500 ÷ 5,000 = ₹500.90. Add a last trade of 10 shares at ₹499.00, and it is 25,09,490 ÷ 5,010, which is still about ₹500.90. The screen's last price was ₹499.00, yet the close is about ₹500.90. That gap is why the last price you saw is not the close.

Now take a share with a closing auction. The reference price is the average of trades from 3:00 to 3:15 pm, say ₹500.00. The band is ±3%: 500 × 0.03 = ₹15, so ₹485.00 to ₹515.00. Orders can be placed only inside this band. The table shows how many shares can trade at each price.

A block deal is a very large trade done in a set window. A bulk deal is a normal trade that is reported once it passes 0.5% of a company's shares. They are different things: one is defined by where and how it is done, the other only by how big it is across a day, and both end up in a public report.

A block deal is like a wholesale buyer agreeing a rate with a farmer outside the open auction. A bulk deal is a big buyer in the open mandi, noted in a ledger. The comparison shows the split, but block deals have fixed rules about timing, price and size that a wholesale deal does not.

SEBI's circular of 8 October 2025 sets two windows for block deals. The morning window is 8:45 to 9:00 am, with the previous close as reference. The afternoon window is 2:05 to 2:20 pm. Its reference is the average price of cash trades from 1:45 to 2:00 pm. Check nseindia.com for the current windows.

Orders must be within 3% of the reference. If the previous close is ₹500.00, that is ₹485.00 to ₹515.00. The minimum size is ₹25,00,00,000 (₹25 crore): 5,00,000 shares × ₹500 = ₹25,00,00,000. Every block trade must end in delivery, and the exchange publishes the share (scrip), client, quantity and price the same day, after market hours.

A bulk deal has no special window. It happens in normal trading at the normal market price, and it is reported once it passes 0.5% of a company's listed shares in a day. Say Sabzi Wala has 10,00,000 listed shares. Then 0.5% = 10,00,000 × 0.005 = 5,000. A client trading more than 5,000 in a day is reported.

For a bulk deal the broker discloses the share (scrip), client, quantity and price. Both kinds of deal are therefore reports, not signals. A report tells you that a client traded and at what price, but it does not tell you why. Treat it as a fact about a past trade and nothing more.

T is the trade day, and T+1 is the next day on which settlement can happen. Weekends and holidays are skipped, so T+1 is a count of working days and not of calendar days. A Thursday trade settles on Friday only if Friday is open for settlement. Otherwise the count moves on to the next day that is open.

Think of a courier that promises delivery in one working day. It does not deliver on Sundays or its own holidays. The shop's holidays and the courier's can differ, which is the settlement holiday case. A day can be open for the shop and shut for the courier, and then the parcel waits.

To count, move forward one working day. Skip Saturdays, Sundays and every holiday on the trading or settlement list. NSE Clearing states that all intervening holidays are excluded. Each trade day has its own settlement day, so trades made on different days settle on different days, even though the rule is the same.

The table uses dates from the exchange calendars. Tuesday 25 August 2026 skips Wednesday 26 August. The market was open that day, but it was a settlement holiday. So a trade on Tuesday 25 August, and a trade on Wednesday 26 August as well, both settle on Thursday 27 August 2026.

An optional same-day settlement, T+0, runs beside T+1 for a limited list of shares. The exchange publishes that list each day. Most shares settle on T+1. An open market also does not mean shares move that day. How soon your app shows the credit is a separate matter, set by your broker and depository.

On settlement day the clearing corporation first collects what each side owes, called pay-in. Then it hands over what each side is due, called pay-out. Settlement runs between brokers and the clearing corporation, not between Asha and Ravi directly, so the two never need to meet or trust each other.

Think of the mandi's evening hisab. All dues are collected first, and then each seller is paid. The comparison holds for the order of steps, collect first and pay later. It stops at the parties, because here the settlement runs through brokers and a clearing corporation and not through one trader's notebook.

Take Asha's trade from section 7. It was matched on Thursday 1 October 2026: 10 shares at ₹200.00, so ₹2,000 is owed. Nothing moves on Friday, Saturday or Sunday, because Friday is a trading holiday and the weekend is skipped. The obligation simply waits for the next settlement day, and no money or shares change hands until then.

On Monday 5 October, pay-in comes first. Asha's side hands over ₹2,000, and Ravi's side hands over 10 shares. Then pay-out follows: 10 shares go to Asha's demat account, and ₹2,000 goes to Ravi's broker. Only after both steps is the trade fully settled, and the exchange's calendar fixes the day on which all of this happens.

Asha's position now becomes a holding. Many apps show a position first and a holding after settlement, and the names differ by app. The depository, NSDL or CDSL, keeps the official record. Money and shares do not move the moment you tap Buy, and the hour your app updates is your broker's and depository's timing.

Short delivery means a seller's shares are missing on settlement day. The clearing corporation buys them in an auction, and the seller bears the cost. The buyer is not left waiting without a remedy: the buy-in is the rule fixed in advance for exactly this failure, and it keeps the market's settlement running.

Picture a caterer who fails to deliver the sweets on the day. The host buys from another shop at a higher rate, and the caterer pays the difference. Here the rule and the buying step are fixed in advance, and nobody negotiates the price of the replacement. That price comes from an auction.

Say Ravi sells on Monday (T), but his 10 shares are missing on Tuesday (T+1). The auction is held on Tuesday and settled on Wednesday (T+2). Asha's shares arrive a day later, and she is not charged for the failure. What a given broker passes on to a client is the broker's rule.

In the simplified example, the auction fills at ₹230.00. That is 10 × 230 = ₹2,300, so Ravi bears 2,300 − 2,000 = ₹300 plus charges. The exact entry uses a valuation price and your broker's terms, so these figures are simplified. They match the figures in the lesson on how an exchange works.

If the auction finds no seller, the shortage is closed out instead, at a price set by a fixed rule that the next heading explains with figures. In both cases the buyer does not pay extra in this example, and the cost falls on the seller who failed to deliver. The figure above lets you switch between the two cases.

Every sale has its own settlement day, one working day after the sale. A same-day sale of a same-day purchase is netted, so for that pair no shares move at all. This is the whole rule. The rest of this section shows it on a calendar, one day at a time, using a purchase on Monday.

Many learners ask: can I sell shares I bought today? BTST (buy today, sell tomorrow) is only a market nickname. The exchange rules deal with trades and settlement days, not the nickname. So the useful question is not what the trade is called but on which day each trade settles.

Think of reselling a parcel before it reaches your door. The dealer may list it, and trouble comes only if the first parcel does not arrive. Shares of one company are identical, so any delivered shares will do. The comparison stops where the parcel is one object, while shares are pooled and netted.

Asha buys 10 at ₹200.00 on Monday, and the purchase settles on Tuesday. A sale on Monday is netted with the Monday purchase, so no shares move. A sale on Tuesday settles on Wednesday, and her 10 shares arrive on Tuesday. A sale on Wednesday settles on Thursday and is made from shares she already holds.

If Ravi fails to deliver, her shares arrive through the auction a day later, as section 9 showed. Executed in your app does not mean you hold the shares. Whether your broker allows a sale before the shares are credited is the broker's rule, so check your own account for what you hold.

An order entered while the market is shut is an instruction your broker holds. Its price is found when the market opens. It is not a trade, because no buyer and seller have met yet. Until the opening, it is only a note held by your broker, and you can read its status in your app.

Think of leaving a note with the vegetable seller the night before. It says: buy 10 kg if the rate is up to ₹198. The note is not a deal. The rate is fixed in the morning. Overnight news can change that rate, and the note does not know about it.

Many brokers let you queue an order, often called an after-market order (AMO). The exchange's own day starts with the pre-open session from 9:00 am. The opening price is found by auction, as in section 3, with matching from 9:10 to 9:12 am, so the price is not known at 9:00 sharp.

Now put numbers on it. Say the previous close is ₹200.00, and the next opening auction finds ₹201.00. Asha queues a limit buy of 10 at ₹198.00. It is not filled, because ₹201.00 is above ₹198.00. A market buy of 10 pays the price the auction finds: 10 × 201 = ₹2,010.

A queued order does not trade at last night's close. The broker's cut-off times and accepted order types are the broker's rules, so check your app. Order types have their own lesson. News can arrive overnight, and a queued order does not know it, so the opening auction finds the price that day, not the broker.

The exchange publishes each year's trading holidays, settlement holidays and special sessions. So the calendar is read from its notices, not from memory. A trading holiday is a day the exchange is shut, and a settlement holiday is a day shares and money do not move. The two lists are not identical, and each is published separately.

Think of a school's yearly calendar and the school bus operator's calendar. Both are published, and they are not identical. A day can be a school day with no bus. The exchange's calendar is set by notice and can be amended, so a date that was a working day last month may change.

For 2026, NSE's circular of 12 December 2025 lists the weekday trading holidays. It adds four holidays that fall on weekends: 15 February, 21 March, 15 August and 8 November. A date, 15 January 2026, was later added to the NSE list for a municipal election. So the list as first published is not the current list.

NSE Clearing's list of 22 December 2025 gives the settlement holidays. Four weekday dates in it were settlement-only: 19 February, 19 March, 1 April and 26 August. On those days the market is open, but no shares move. Whether the later 15 January change also altered the settlement list is not covered here, so check the current clearing list.

Special days sit outside both lists. Some are announced by notice for a reason of their own, like a festival session or a Budget day. The three below show how different they can be. Other markets keep separate hours as well, so the equity cash timings in this lesson should not be carried over to them.
