I think you will find that the difference will never be what Hugo quotes , as he is referring to the actual Dow and Ftse prices, whereas Fins and others use the Futures prices.
I don't think it makes any/much difference to the profitability of each trade, because as each index changes, Fins will change their price approx the same amount.
If I am wrong, Hugo (or someone) will correct me when he reads this.
