CFDs and Indicative Open

Hi all,

Just a quick question in relation to CFDs and the ASX indicative open price. Knowing the previous close and the indicative opening price, using over-the-counter CFDs, is it theoretically possible to place an order to open at the last close and then the moment the market opens, sell at the opening price?

Cheers

You can buy on the close and sell on the open sure but you cannot buy yesterdays close today.
