Hmm Guy idont know who ur gonna trade with,r u gonna use spreadbetting ?
By spread i mean the bid and Ask price which all brokers or s/betting companies quote.
1 point is probably the best u will ever get.S/beters chrge no commision but quote minimum 3 point spreads.So you have to make six points to just break even.
IB charge abt $2.30 to enter a position and the same to close.
