Oct 7 IG Group Holdings Plc has changed the terms of client accounts that were affected by a surge in the Swiss Franc earlier this year after intervention from the UK’s Financial Ombudsman Service . The FOS agreed that the online trading platform had acted in accordance with terms and conditions of a client agreement during the Swiss franc’s surge on Jan. 15. It, however, added that a contract that was beneficial to clients would have been more reflective of the underlying market liquidity during unprecedented market circumstances, IG Group said in a statement.
