Ion Trading said it is buying the company because it believes that finvision’s pricing functionality will complement its own trading and quoting products.

Finvision co-founders Jens Kramer and Markos Mouzouris are to remain as directors of the business and will join the Ion management team as part of the agreement.

Ion recently acquired New York-based Aurora Software, a provider of front-office risk management technology for US Treasuries, Mortgages and Options trading desks.
