Market
A market is any place or system where buyers and sellers meet to exchange an asset at a price they both accept.
A market is where buyers and sellers meet and agree a price. In trading it can be a stock Exchange, an electronic network, or a dealer quoting prices. Whatever its form, a market turns many different opinions into one tradable price.

A market in plain words
Traditional exchanges are markets that bring many buyers and sellers of financial instruments together in one place.1
A trading facility is any system where many participants can trade by accepting each other's bids and offers.2
A bid is an offer to buy a specific quantity at a stated price, and an offer is a willingness to sell at a given price.2
How a market works
Buyers post bids
Buyers state what they will pay.2
Sellers post offers
Sellers state what they will accept.2
Orders meet
An electronic network can automatically match buy and sell orders at specified prices.3
Dealers fill gaps
A market maker stands ready to buy or sell at publicly quoted prices.3
A price forms
Each matched trade becomes the latest price.
The cycle repeats
New orders keep moving the price through the session.
Worked examples
Example 1 — Buyers in charge
Price risesIn a hypothetical market, more buyers arrive and raise their bids from 20 to 21.
| Old price | 20 |
| New price | 21 |
Because a market brings together buyers and sellers, stronger buying lifts the agreed price.1
Example 2 — Sellers in charge
Price fallsMany sellers lower their offers from 50 to 48 to find buyers.
| Old price | 50 |
| New price | 48 |
Sellers signal willingness to sell at a given price; lower offers pull the price down.2
Example 3 — Balanced market
Price steadyBids sit at 9.99 and offers at 10.01 for a hypothetical share all morning.
| Bid | 9.99 |
| Offer | 10.01 |
Matching systems pair buy and sell orders at specified prices, so trades keep printing near 10.3
