Order book (trading)

As Blotter (of English. Blotting paper ) a temporary list of open positions is referred to in trading securities and commodities. The term comes from the time before the introduction of the computer-based trading, as traders noted the open transactions on their writing pad. From there, the shops were transferred at the end of the trading day in a more permanent form of storage. In computer- based trading, this function has received by traders during the day to enter their shops in spreadsheet - like form in the Blotter, from where they are transferred during the passage of the post -execution processes in the trading and risk management.
