...trade size is 5x, so the commission works out at only 0.35 p for me per share equivalent...
am i right with this?
5000 x £0.0035 = £17.50 transaction cost.
hmmm, who is your broker, IB?
the other thing to consider with Liffe vs spreadbet is potential costs of early exercise of stock against you (i know on paper being exercised is not a problem, but you rarely benefit after ALL costs are taken into account), as with spreadbets you have no exercise of stock.
guess it depends on ones own circumstances.
i seem to remember RobinT and tilton use spreadbets.
