A trade in plain words
Where and how your order is executed affects its total cost, including the price you pay.1
After execution comes settlement: the shares officially pass to the buyer and the cash to the seller.2
When traders count a complete trade, they often mean a round turn — a buy plus the sale that closes it, or a short plus the buy that covers it.3
How a trade happens
Choose the order
A market order buys or sells immediately.4
Or set a price
A limit order trades at a specific price or better.4
Send to the broker
Trade execution isn't instantaneous; the broker routes your order.1
Get executed
The venue and route can affect the price you pay.1
Settle
In the US, stock trades now settle one business day after the trade.2
Close and record
Closing the position completes the round turn.3
Worked examples
Example 1 — Winning round trip
GainA hypothetical trader buys at 8 and sells at 9.
| Buy | 8 |
| Sell | 9 |
Buying and later selling forms one round turn, closing with a gain.3
Example 2 — Costly execution
Higher costA hypothetical market buy expected at 40 fills at 40.30 in a fast market.
| Expected | 40.00 |
| Filled | 40.30 |
How an order is executed can affect the price you pay, adding cost.1
Example 3 — Waiting to settle
Cash next dayA hypothetical trader sells shares and checks when the cash arrives.
| Trade date | Day 0 |
| Settled | Day 1 |
Under T+1, transactions settle in one business day of the transaction date.2

Execution

Settlement

Settlement is the official transfer of securities and cash between buyer and seller, and US trades now settle in one business day.2

The CFTC's round turn combines a purchase and a liquidating sale into one completed transaction, which is how most trade statistics are counted.3
