TruMid is one of several firms trying to take advantage of increased interest in electronic bond trading at a time when many are complaining about reduced liquidity. Many have struggled to gain traction in a market that is one of the last to switch to electronic platforms. TruMid focuses on roundlot trading, matching buy and sell orders in excess of $1 million. The firm launched around two years ago with a group of well-known Wall Street traders, capturing headlines as a result. It has also attracted big name backers such as Soros and Thiel, while former Barclays CEO Bob Diamond has endorsed the platform.
