Trading and Settlement Overview: Trade Life Cycle and T+1 Settlement

Updated 11 October 2026 · Fact-checked

The trade life cycle is the path of a trade: order placement, order matching on the exchange, trade confirmation, clearing (working out obligations), and settlement (pay-in and pay-out of funds and securities). India uses rolling settlement. In the T+1 cycle, a trade done on day T settles on the next working day.

Understand Trading and Settlement Overview

A trade in the stock market does not end when your order is matched. Matching only creates a promise. The buyer must pay money and the seller must deliver shares. The rest of the life cycle makes sure both promises are kept.

The flow runs in order. The investor gives an order to a stockbroker (trading member). The broker enters it on the exchange trading system. The system matches buy and sell orders and generates a trade. The broker then gives the client a contract note with the trade details.

After trading comes clearing. The clearing corporation collects trade details from the exchange, confirms them, and works out what each clearing member must pay or deliver. Obligations are generally netted, so a member ends up with one net funds amount and one net securities quantity per security. The clearing corporation also becomes the counterparty to each trade through novation, which reduces the risk that the other side defaults.

Settlement is the actual movement. In pay-in, members give funds and securities to the clearing corporation. In pay-out, the clearing corporation hands funds and securities to those entitled to them. Funds move through clearing banks. Securities move in dematerialised form through the depositories and depository participants.

India follows rolling settlement: each trading day's trades settle a fixed number of working days later. The cycle is T+1, where T is the trade day. A trade on Monday settles on Tuesday. If the next day is a settlement or trading holiday, it moves to the next working day. Exchanges may also offer an optional T+0 settlement for a limited set of trades, but T+1 is the standard cycle to remember.

Key formulas to remember

Rolling settlement cycle: Settlement day = T + 1 working day; T is the trade day. Holidays are not counted, so a Friday trade normally settles on Monday.
Trade life cycle order: Order → Matching → Trade confirmation → Clearing → Settlement (pay-in, then pay-out); Exam options often shuffle this order. Pay-in always comes before pay-out.
Net obligation: Net obligation = Total buys − Total sells (per security, per member); A positive result means the member must receive the securities. A negative result means the member must deliver them. Funds are netted in the same way.
Who does what: Exchange = matching | Clearing corporation = clearing and guarantee | Depository = securities movement | Clearing bank = funds movement; Use this one-line map to eliminate wrong options on roles.

How to solve Trading and Settlement Overview questions

Most questions on this topic test sequence, roles or timing. Use the same method each time.

1Identify what the question asks: a sequence, a role, a timeline or a definition.
2Place the event in the life cycle: order, matching, confirmation, clearing or settlement.
3For roles, link the activity to the right body: exchange for matching, clearing corporation for obligations and guarantee, depository for securities, clearing bank for funds.
4For timing, count T+1 in working days. Skip weekends and holidays.
5Check whether the question is about clearing (working out obligations) or settlement (actual transfer). They are different.
6Eliminate options that put pay-out before pay-in or give a task to the wrong body.
7Choose the option that fits every condition in the question.

Quickest way: Sequence and role shortcut

When to use it: Use when you have under a minute and the options list steps, bodies or settlement days.

Recall the chain: Order, Match, Confirm, Clear, Settle.
Remember the motto: exchange matches, clearing corporation nets and guarantees, depository and bank move assets.
For dates, add one working day to the trade day.
Cross out any option that breaks the chain or swaps a role, then pick the remaining one.

Common mistakes in Trading and Settlement Overview

Treating clearing and settlement as the same thing.
People often use the two words together as one phrase.
Fix: Clearing is working out and confirming obligations. Settlement is the actual transfer of funds and securities.
Counting weekends or holidays in T+1.
Students think of T+1 as simply the next calendar day.
Fix: Count working days only. A Friday trade settles on Monday unless Monday is a holiday.
Saying the exchange settles the trade.
The exchange is the most visible body in the process.
Fix: The exchange matches orders. The clearing corporation handles clearing and settlement, with depositories and clearing banks moving securities and funds.
Putting pay-out before pay-in.
Students focus on the investor receiving shares or money.
Fix: The clearing corporation can pay out only after it has received pay-in from members.
Confusing rolling settlement with account period settlement.
Older material mentions weekly account periods.
Fix: In rolling settlement, every day's trades settle after a fixed number of days. Today that is T+1.

Worked examples

Example 1

A trade is executed on Wednesday. There is no holiday that week. Under the T+1 rolling settlement cycle, on which day is it settled?

Show the solution

T is Wednesday, the trade day.
T+1 means one working day later.
The next working day after Wednesday is Thursday, and no holiday intervenes.

Answer: Thursday

Example 2

Which of the following correctly gives the order of the trade life cycle? (a) Order, clearing, matching, settlement (b) Order, matching, clearing, settlement (c) Matching, order, settlement, clearing (d) Order, settlement, matching, clearing

Show the solution

An investor first places an order, so order is first.
The exchange system then matches orders to create a trade.
Clearing follows, as obligations are worked out and netted.
Settlement is last, when funds and securities actually move.
Only option (b) follows this sequence.

Answer: (b) Order, matching, clearing, settlement

Exam tips

Expect sequence questions. Memorise Order, Match, Confirm, Clear, Settle.
Know the role of each body. Exchange, clearing corporation, depository and clearing bank each have a different job.
Remember that T+1 counts working days and is the standard rolling settlement cycle.
Read carefully when a question says clearing or settlement. The two words point to different stages.
Where the module has negative marking, skip an option you cannot place instead of guessing among all four.
