Exchange Delivery Settlement Price
Exchange Delivery Settlement Price, or "EDSP", is the price determined by an Exchange used to make payments on cash settled futures contracts.
It is the physical delivery costs of an underlying contract and is often based on the average price of trades over a set time period (see the LSE rules lined below). Usually, this is based on an index of the intraday prices or an average of the opening and closing price for the relevant day.
On the London Stock Exchange the EDSP for FTSE 100 and 250 Index Futures and Options Contracts is based on the Index value created by the intra-day auction in each of the constituent securities which is run specifically for that purpose by the London Stock Exchange.
