1911 Encyclopædia Britannica/Making-up Price

MAKING-UP PRICE, a term used in the London and other British Stock Exchanges, to denote the price at which speculative bargains are carried over from one account to the next. The carrying over of a “bull” position in Eries, for example, implies a sale for cash and a simultaneous repurchase for the new account, both bargains being done at the making-up price. This is fixed at noon on carry-over day, in accordance with the market price then current (see Account; Stock Exchange). The term is also used in New York, where the making-up prices are fixed at the end of a day’s business, in accordance with the American system of daily settlements.
