Today i had a relatively large position with IG (australia 200 index cfd). At the close of trade (4.00pm - 4.10pm), the market ran up about 20 points, giving me a max $2000 profit. I tried to sell the contracts but the my account froze, identified by a red arrow. When i ran my mouse over the position it told me the market was closed for action. By the time the market re-opened, (4 mins later) i was down $550. My question is, does anybody trade IG and was their australia 200 accounts closed between 4.02pm to about 4.06pm today the 19/3/14.
