I need to free some cash and want to switch some shares to SSF's planning to keep my risk profile and exposure similar to my current status. I have read all the relevant info but still have some questions. At Quote, Day comparison, price: This is the offer price from SBK but where can one find the last trading price? What does market to market mean? How is the value traded determined ? What does the open interest (contracts) mean? On the price matrix, can one determine potential profit if you use the current share price and the expected share price and the diff's between the bid and offer prices? When you scroll down there is a note what says it says 'purely indicative'?
