Any purchase or sale of securities between two members of the London Stock Exchange .
The term bargain is used interchangeably with the term contract . No special price is implied by the use of the term. Figures showing the turnover of the London Stock Exchange are published detailing the number of bargains.
If you want to make a comparison of business levels between the London market and others around the world you need to halve the London figure. This is because the Exchange authorities collate their statistics on the basis of the broker's contract note, which reports the deal to the client. This means each trade will be reported twice, with the buyer and the seller each getting a contract note, even though only one block of shares has changed hands.
