Perhaps a basic question to many of you, but I need a little clarification. I have been running a demo account with some small success. However, as the dollar / GBP has changed, my 'fund' would seem a lot higher than just my 'winnings'. This is fine at present, but it could obviously go the other way, where the fund increases but after changing to GBP the value is less than started. Am I correct in this, is there any way to do something about it, and is this where hedging comes in? If so, could someone give me some advice here please.
