Market Timings and Settlement

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.

Here is a real day. On Monday 19 October 2026, ITC Ltd (NSE: ITC) opened at ₹262.70, after a previous close of ₹263.50 on Friday 16 October. Mr. Chartist, the course's fictional guide, buys 10 shares at the open through his broker, Sahi. The trade value is 10 × ₹262.70 = ₹2,627.00 before charges (derived). The price is real, from NSE's daily report (bhavcopy); the quantity of 10 is an illustration. The seller is unknown to him, because the order book is anonymous.

Tuesday 20 October 2026 was Dussehra, a trading holiday and a settlement holiday. So the regular settlement is Wednesday 21 October 2026, subject to successful delivery. His app showed Executed on Monday, but Executed means matched, not delivered. Wednesday is the scheduled settlement day; a broker's pending holding display is not proof of demat credit. Check the depository record or credit notification.

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 visual 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.

Start with a familiar broker screen: an order can be queued before trading, matched during an active session, or remain unfilled. These are different states. The exchange sets each session's hours; a broker's order-entry window does not extend exchange trading.

These times have changed more than once in about a year. Block deal rules changed in October 2025. SEBI's circular of 16 January 2026 brought in a closing auction from 3 August 2026, and a revised pre-open 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. ITC has stock futures (its November contract traded on 19 October 2026), so ITC follows the 3:15 pm clock. 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 during the pre-open entry window 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 starts immediately after random order-entry closure between 9:08 and 9:10 am and continues up to 9:12 am, and a short buffer follows before continuous trading begins.

In an opening auction, bids are buyers' offers and asks are sellers' requested prices. The exchange collects these orders, then uses its auction rules to find one opening price. The price shown while collection is open is only indicative; it can change.

Take ITC on Monday 19 October 2026. The previous close was ₹263.50, and the day opened at ₹262.70 (both real). Say Mr. Chartist's limit order buys 10 shares at up to ₹263.00 (the limit is an illustration). He pays 10 × ₹262.70 = ₹2,627.00, not 10 × ₹263.00 = ₹2,630.00 (derived), because every matched order trades at the one opening price.

A seller's limit at ₹262.00 works the same way (also an illustration). That seller receives 10 × ₹262.70 = ₹2,627.00, not 10 × ₹262.00 = ₹2,620.00 (derived). 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. Its original exchange-received timestamp is retained under the applicable carry-forward rules. 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. If no opening price is found, the first trade in normal trading becomes the open.

Stop-loss, IOC and disclosed-quantity orders are not allowed in this session. A market order trades at the price the auction finds, and market orders get matching priority.

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.

Read the two sides together: a buy order can match an available sell order at a compatible price. A submitted order is not automatically a trade. At the same price, priority follows the time the exchange received the order, not the time you opened your app.

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.

On 19 October 2026, ITC traded between a low of ₹259.95 and a high of ₹263.90 (real). Say Mr. Chartist had placed a day limit buy of 10 at ₹259.50 (an illustration). That is below the day's real low, so it never filled that day (derived).

ITC has a closing auction. Its band is ±3% of a reference price, the average of trades from 3:00 to 3:15 pm. NSE does not publish that reference, so take the real close of ₹260.80 as a stand-in for illustration: 260.80 × 0.03 = ₹7.824, so about ₹252.98 to ₹268.62 before rounding to the 0.05 tick (derived). The unfilled ₹259.50 day order sits inside that band, so it is carried into the closing auction. A limit at ₹250.00 is outside the band, so it is not carried and expires. In a share without a closing auction, an unfilled day order simply expires at the end of the day. An IOC order never waits at all.

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, under SEBI's circular of 16 January 2026. Closing prices are used in market benchmarks, portfolio valuations and relevant settlement calculations. A closing price is an official daily reference, not a promise about tomorrow's opening price.

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.

First, a share with no closing auction. These trades are made up, to show the arithmetic only. 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 a share with a closing auction: ITC. Its real close on 19 October 2026 was ₹260.80, set by the closing auction. The auction's order book is not published, so the quantities in the table are an illustration around that real price. The reference price is the average of trades from 3:00 to 3:15 pm, and orders are allowed only within ±3% of it.

How the auction picks the close. The close is the price where the most shares trade. If two prices tie, the one with the least unmatched quantity wins, and if that also ties, the price closest to the reference price wins. If no price can be found at all, the reference price itself becomes the close. In the table, 800 shares trade at ₹260.80, the most, so ₹260.80 is the close.

What the auction accepts. The auction takes limit and market orders only; stop-loss, iceberg and disclosed-quantity orders are not accepted. Its stages, from SEBI's circular: 3:15 pm reference price, 3:20 pm order entry (limit and market), 3:25 pm limit orders only, entry closes at a random moment between 3:28 and 3:30 pm, then matching from 3:30 pm. Unexecuted day limit orders that sit inside the band are carried into it. A market buy of 10 trades at the price found, so here it costs 10 × 260.80 = ₹2,608.00 (derived).

Other shares and post-close. If a share has no trade in the last half-hour, its last traded price of the day is the close. A post-close window runs 3:50 to 4:00 pm for both groups of shares. Orders match at the closing price in that window, and no new price is found. So a trade there cannot move the close that was already set.

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.

For a beginner, separate the mechanism from the disclosure. A block deal uses a dedicated exchange window and minimum deal value. A bulk deal is identified from a client's total buying or selling during the day, even when the trades happened in ordinary trading.

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, with the volume-weighted average of cash trades from 1:45 to 2:00 pm as reference. The same rules also apply to the block window for T+0 trades. Check nseindia.com for the current windows.

Orders must be within 3% of the reference, subject to applicable security price bands. Take ITC's morning window on 19 October 2026. The reference is the previous close, ₹263.50 (real). So 263.50 × 0.03 = ₹7.905, and the range is about ₹255.60 to ₹271.40 on the 0.05 tick (derived). The minimum size is ₹25 crore (₹25,00,00,000). At ₹263.50 that is at least 9,48,767 ITC shares, because 25,00,00,000 ÷ 263.50 = 9,48,766.6 (derived; an illustration of the rule, not a real deal). 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 one client's total passes 0.5% of a company's listed shares in a day. ITC has about 1,253.05 crore shares. So 0.5% is about 6.27 crore shares (1,253.05 crore × 0.005, derived). A client trading more than that in ITC in a day is reported. Compare Mr. Chartist's ₹2,627.00 trade: far below both lines.

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 Monday trade settles on Tuesday only if Tuesday is open for settlement. Otherwise the count moves on to the next day that is open. India finished moving every share to T+1 on 27 January 2023.

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 date is assigned a settlement date. Different trade dates can share a settlement date when an intervening settlement holiday is skipped.

Mr. Chartist's ITC trade shows the first case. He bought on Monday 19 October 2026. Tuesday 20 October was Dussehra, both a trading and a settlement holiday. So T+1 is Wednesday 21 October 2026. The second case is a settlement-only holiday. On Wednesday 26 August 2026 the market was open, but settlement was not processed. So trades of Tuesday 25 August and Wednesday 26 August both settled on Thursday 27 August 2026 (NSE Clearing circular of 11 August 2026).

An optional same-day settlement, T+0, runs beside T+1. It started as a beta on 28 March 2024, runs as one session from 9:15 am to 1:30 pm, and was widened in 2025 to more shares. NSE notices in September 2026 show it still running. Its prices do not count towards the index or the close. Eligibility and broker support must be checked against the exchange's current T+0 list. Most trades settle on T+1, and T+0 is not automatically applied to every order in an eligible share. The time your app updates is separate from the official demat record.

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. For NSE trades the clearing corporation is NSE Clearing. Obligations run through brokers (clearing members) and NSE Clearing, not between Mr. Chartist and the seller directly, so the two never need to meet or trust each other.

Pay-in means meeting the settlement obligation; pay-out means receiving what is due. Keep the two assets separate: the buyer's side owes funds, and the seller's side owes securities. Funds use clearing banks, while securities use the depositories, CDSL and NSDL. HDFC Bank, where Mr. Chartist banks, is one of NSE Clearing's 14 clearing banks.

Take Mr. Chartist's ITC trade from section 7. It was matched on Monday 19 October 2026: 10 shares at ₹262.70, so ₹2,627.00 is owed (derived). The regular settlement is Wednesday 21 October, after the Dussehra holiday. His broker, Sahi, may collect or block the money earlier. The scheduled settlement date is different from when you fund the account.

On Wednesday 21 October, the day runs to a timetable. Final obligations are ready by 9:00 am (SEBI's schedule). Pay-in of money and shares is due with NSE Clearing by 10:30 am. Money pay-out follows from 1:30 pm, so ₹2,627.00 reaches the seller's broker. Share pay-out comes by 3:30 pm, straight into Mr. Chartist's demat account. Only after both steps is the trade fully settled.

A contract note should be issued within 24 hours of trade execution. Check the security, executed quantity, price and charges against your order history. The contract note confirms the trade; check the depository statement separately to confirm securities credit.

Mr. Chartist'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.

Selling what you bought today (simplified). Mr. Chartist buys 10 ITC at ₹262.70 (₹2,627.00) on 19 October and sells the same 10 at ₹263.00 (₹2,630.00) the same day. The sale price is an illustration inside that day's real range. The shares to deliver after netting are 10 − 10 = 0, so no shares move. The money is 2,630.00 − 2,627.00 = ₹3.00 received (derived). Charges and tax are left out, and they would likely be more than ₹3.00, so the pair could end in a loss.

Trade-for-trade shares. Some shares are placed in a trade-for-trade segment for surveillance. There every trade settles in full and nothing is netted, so a same-day sale needs shares you already hold. The idea of netting from the previous paragraph therefore does not apply. Check your app for the segment a share is in before you plan a same-day sale.

Direct credit. Under SEBI's direct pay-out framework (circular of 10 October 2024), NSE Clearing pays out shares directly to clients' demat accounts by 3:30 pm. Custodian clients, unpaid shares (pledged to the broker) and margin-funded shares are handled separately, so it is not accurate to say the broker can never be involved. The depository keeps the official record, and the time your app shows the change depends on your broker and the depository.

Short delivery means the required shares are not delivered on settlement day. In normal rolling settlement, the clearing corporation generally conducts a buy-in auction; applicable cases instead use cash close-out. The defaulting seller bears the prescribed costs. 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.

Suppose, as an illustration, that the seller of Mr. Chartist's ITC shares is short on Wednesday 21 October 2026 (T+1). The auction is held that day and settled on Thursday 22 October (T+2). If the auction succeeds, his shares arrive a day later, and he is not charged for the failure. What a given broker passes on to a client is the broker's rule.

Say the auction fills at ₹265.00 (an illustration). That is 10 × 265.00 = ₹2,650.00, so the seller bears 2,650.00 − 2,627.00 = ₹23.00 plus charges (derived). The exact entry uses a valuation price and the broker's terms, so these figures are simplified.

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, and the cost falls on the seller who failed to deliver. The visual separates share delivery through auction from a cash close-out.

If no seller is found. For the normal market, NSE closes out at the higher of two prices; segment-specific and corporate-action exceptions must be checked. One is the highest price across exchanges from trade day to auction day. On NSE, ITC's highs were ₹263.90 on 19 October and ₹264.85 on 21 October (real), so ₹264.85 on NSE. The other is 20% above the settlement price on the auction day. Using the 21 October close of ₹262.00 as a stand-in: 262.00 × 1.20 = ₹314.40 (derived). The higher is ₹314.40, so the close-out is 10 × 314.40 = ₹3,144.00. The seller bears 3,144.00 − 2,627.00 = ₹517.00 plus charges. This is an illustration of the rule; no such close-out is known to have happened.

Trade-for-trade shares. A shortage in a trade-for-trade share is closed out directly, with no auction. This follows from how the segment works: every trade settles in full and nothing is netted, so each missing delivery stands on its own. As in the ordinary case, the cost falls on the seller who failed to deliver.

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 regular T+1 framework for normal rolling settlement, not a rule for every segment. The rest of this section shows it on the real October 2026 calendar, one day at a time.

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.

Mr. Chartist buys 10 ITC at ₹262.70 on Monday 19 October 2026, and the purchase settles on Wednesday 21 October. A sale on Monday is netted with the Monday purchase, so no shares move. Tuesday 20 October was a holiday, so no sale is possible that day. A sale on Wednesday settles on Thursday 22 October, and his 10 shares arrive on Wednesday by 3:30 pm. A sale on Thursday settles on Friday 23 October and is made from shares he already holds.

If the seller fails to deliver, Mr. Chartist's purchase may need a buying-in auction or cash close-out under the applicable rules. Successful auction delivery completes on T+2, here Thursday 22 October; a cash close-out provides money instead of shares. Neither means shares are guaranteed to arrive a day later. If he has already sold those expected shares on Wednesday, delayed or missing delivery can stop him meeting that sale's Thursday delivery and create a separate shortage and costs. Check credited holdings, the sale's pay-in deadline and the broker's supported process before selling shares not yet received. Executed in the app does not prove demat credit.

An order entered while the market is shut is an instruction your broker holds. Its execution price is determined only if it later matches during an eligible session. 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 a scheduled instruction saved in your broker app. Saving it after market hours does not mean the exchange has accepted it or that anyone has traded with you. The broker must transmit it into an eligible session, and the usual price and quantity conditions still apply.

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 after order entry closes at a random moment between 9:08 and 9:10 am, continuing up to 9:12 am, so the price is not known at 9:00 sharp.

Now put real prices on it. ITC closed at ₹260.80 on Monday 19 October 2026, and the market was shut on Tuesday for Dussehra. Say Mr. Chartist saves a queued limit buy of 10 at ₹260.00 on Tuesday evening (an illustration). On Wednesday 21 October, ITC opened at ₹261.00 (real), above his limit, so the order is not filled at the open. The day's real low was ₹260.15, so it never filled that day (derived).

A queued market buy of 10 instead would, if it matched in the opening auction, cost 10 × 261.00 = ₹2,610.00 before charges (derived). A queued market order does not guarantee a fill. 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.

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 the relevant clearing settlement is not processed. 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 15 weekday trading holidays, including Gandhi Jayanti on 2 October and Dussehra on 20 October. It adds four holidays that fall on weekends: 15 February, 21 March, 15 August and 8 November. On 12 January 2026, NSE added 15 January 2026 as a trading holiday for municipal elections in Maharashtra (as reported in the press). So the list as first published is not the current list.

NSE Clearing's 2026 list, published in December 2025, gives 20 settlement holidays. Four weekday dates in it were settlement-only: 19 February, 19 March, 1 April and 26 August. On those days trading continued while regular clearing settlement was not processed. For example, trades of 30 March and 1 April 2026 both settled on 2 April. 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.

Muhurat trading. Muhurat trading is a short session held on Diwali Laxmi Pujan day. In 2025 it was Tuesday 21 October, with the normal market from 1:45 to 2:45 pm, and its trades settled (as reported in the press). For 2026, NSE's circular of 19 October 2026 sets it on Sunday 8 November. The block window runs 1:50 to 2:05 pm, the pre-open 2:05 to 2:20 pm, and normal trading from 2:20 pm. It ends at 3:15 pm for shares with a closing auction, which then runs to 3:35 pm, and at 3:30 pm for other shares. Post-close is 3:50 to 4:00 pm. NSE says all trades in the session result in settlement obligations. The settlement date had not been notified when this was written; Monday 9 November is the next working day (derived), so read the clearing notice.

A Sunday Budget session. On Sunday 1 February 2026, Union Budget day, NSE held a live session with the usual 9:15 am to 3:30 pm hours, announced by NSE in January 2026. Such a session is an exception announced by notice and not a standing rule, so a Sunday is normally a day when the market is shut. The notice for the day decides the hours.

Other segments. Currency, commodity and debt segments run on their own published hours. NSE commodity derivatives trade in a morning and an evening session, and on many equity holidays only the evening session is open. These hours differ from the equity cash timings in this lesson, so do not carry the 9:15 am to 3:30 pm idea over to them. Check each segment's own notice.
