First Derivatives announced mid-February that it has bought the Dublin internet trading firm Cognotec out of receivership. It paid Eu3.4m ($4.6m) for the company. Cognotec was once worth more than Eu150m and employed 200 people, but its value fell in 2007 after it lost its biggest customer. The company was placed in receivership on January 22. It owed about Eu6.9m to Barclays Bank. Cognotec was founded 20 years ago by Brian Maccaba, one of the legendary pioneers of using the internet for foreign exchange trading.
