Deal Blotter
a.k.a. Trade blotter, Blotter
A running log of all trades made by a trader or desk during the day.
In plain English
A running log of all trades made by a trader or desk during the day.
A deal blotter is a dealing desk's diary: every trade, time, price, size and counterparty, written down as it happens. Once handwritten, now electronic.
Back-office staff use it to check and settle trades. For an individual trader, your platform's trade history serves the same purpose.
