You would imagine that Davy Stockbrokers would have the latest technology on their trading platform.
When you did a trade with Campbell O'Connor, on your contract note, you were shown the exact time of your trade (with Davy you are only shown the date of the trade).
Campbell O'Connor also showed you the exact purchase price that you received to 6 decimal points. For example you might have received a price for Tesco at £2.37625. On the Davy platform they just show £2.37.
I agree that if you have a Sterling or US Dollar portfolio that is expressed in Euro in your account, they should display the rate of exchange used to value your portfolio.
