Checking a bargain. London Stock Exchange term; all bargains done between members or firms
are checked next morning in a room in the basement of the exchange before the beginning of
business in the house (exchange). The clerks who perform this work repeat to one another the
terms of the bargain and if there is any dispute refer it at once to their principals ; they are known
as checking clerks and are admitted to the exchange as attendants for their employers, but are
not allowed to transact business, whereas authorized clerks, so called, are allowed to transact
business on the exchange for their employers.
