Size for CFDs means total contract value (number of contracts x value per contract).
Closing price means underlying market price when underlying market closes. For example, CFDs on cash stock indices are undated transactions that do not expire. For each day that a position is open, adjustments are calculated to reflect the effect of interest, and, if necessary, dividends.
A daily interest adjustment is calculated for any position that is opened before 22.00 (London time) and that is still open after 22.00 (London time). For stock index contracts denominated in Australian dollars a daily interest adjustment is calculated for any position that is opened before 16.50 (Sydney time) and that is still open after 16.50 (Sydney time). These adjustments are posted daily to the client's account. Please note that on Fridays open positions will be adjusted for 3 days funding, covering the weekend.
