"The second account can be taxed under CGT, including 50% discount."
Vayama are you sure about that?
Im down as a profesional trader so I miss the 50% tax discount if I was to hold for 12months, never heard anything about using a second account which alows the 50% tax discount, far as I know any acount you trade through is summed up as 1, or do you mean holding it under a company or another persons name?
