What Is Settlement? (T+1 Explained)
Settlement is the transfer of shares and cash that completes a trade after it executes. United States equities settle on the next business day, so the price is fixed at execution while the exchange of assets happens afterwards, and cash from a sale is not immediately reusable.
How it works
A trade has two moments, not one. Execution is when the price is agreed and the obligation is created. Settlement is when the shares actually move to the buyer and the money actually moves to the seller.
The price is locked at execution. Nothing that happens between the two moments changes what you paid. Settlement is bookkeeping, and it is the reason a trade can be “done” and “not finished” at the same time.
United States equities settle on T+1 — trade date plus one business day. A trade on Monday settles Tuesday. A trade on Friday settles Monday, because weekends are not business days, and a public holiday extends it again.
Read the “business” in business day carefully. T+1 is not a promise about hours. A Thursday trade before a Friday holiday settles the following Monday, which is four calendar days.
Settled cash versus buying power
Proceeds from a sale are unsettled until settlement occurs. The balance appears in the account immediately, but in a cash account it is not yet money you are entitled to spend on another purchase you then sell.
Settled cash is the amount you may freely trade with. In a cash account this is the number that governs everything, and it is usually not the number displayed most prominently.
A margin account conceals all of this. The broker advances the funds, so the buying power updates instantly and the settlement cycle becomes invisible. That convenience is a loan, which is precisely why the pattern day trader rule attaches to margin accounts and not to cash ones.
The cycle has shortened repeatedly. United States equities moved from five business days to three in 1995, to two in 2017, and to one in May 2024. Each shortening reduced the window in which one side of a trade can fail before the other is paid.
In practice: trading a cash account
Work through a cash account with $10,000. Buy on Monday and sell the same position on Tuesday. Tuesday’s sale settles Wednesday, so on Tuesday afternoon the proceeds are unsettled and not available for a new purchase you intend to sell again.
Split the account into tranches and the rhythm changes. With $5,000 in each of two tranches, one is always settling while the other is available. That is how active cash-account traders operate without ever borrowing, and it is a scheduling problem rather than a restriction.
Free-riding is the violation this creates. Buying with unsettled funds and selling before the original sale settles means you never had the money at any point. A pattern of it restricts the account to settled cash for ninety days.
A good-faith violation is the milder, more common version — selling a position bought with unsettled proceeds before those proceeds settle. It is a timing breach and it has nothing to do with whether the trade made money.
Settlement does not pause the market. The price keeps moving between execution and settlement, and the exposure is yours the whole time. You own the position from the moment it executes, not from the moment it settles.
Settlement, clearing and transfers
Settlement is not the same as clearing. Clearing is the process of working out who owes what, netting obligations across the day and guaranteeing the trade against a counterparty failing. Settlement is the delivery that follows. One is the accounting; the other is the movement.
It is not a delay in owning the position. The market risk is yours from execution onward, and a price move overnight belongs to you regardless of whether the shares have arrived.
It is not the reason a transfer between brokers takes a week. Account transfers run on a separate system with its own timetable, and confusing the two leads people to expect a cash withdrawal the day after a sale, which is not how the cycle works either.
And T+1 is not universal. It describes United States equities and corporate bonds. Other markets and other asset classes run different cycles, so an account holding several of them is running several clocks at once.
When it fails
The characteristic failure is committing a violation on a profitable trade. Nothing about free-riding depends on the outcome. A trader who made money on every trade of the week can still collect the restriction, which is why it surprises people.
A second failure is misreading the displayed balance. Most platforms show buying power prominently and settled cash somewhere less obvious. In a cash account the second number is the one that binds, and reading the first one is how the violation happens.
A third is assuming every asset settles the same way. Options settle T+1, government bonds typically settle on the trade date or the next day, and mutual funds price once daily. An account holding several asset types has several cycles running at once.
And corporate actions are timed off settlement, not execution. Whether you receive a dividend depends on being a holder of record, which depends on settlement — buying on the ex-dividend date does not entitle you to the payment even though the trade executed before it.
The original data
The corpus measured for this site contains 24,971 videos, and settlement appears in none of them as a subject in its own right. It is the clearest example on this list of a topic that is load-bearing for beginners and invisible in the content that exists.
One figure does carry across. The round trip costs 2% of a typical bar’s range on the site’s shared history whichever account type you use, so the choice between cash and margin is about constraints and leverage rather than about transaction costs.

The pattern day trader rule is what a cash account trades this constraint for. Margin is the account type that hides the cycle behind a loan. And the stock exchange page covers where execution — the other half of the pair — actually happens.
Settlement is the most boring thing on this site and it is the one that decided how I trade. Once I understood that a cash account trades on a two-day rotation instead of a rule, the whole PDT problem stopped being a problem and became a scheduling question.
