A friend who now lives in the Caribbean is deep into 'Forex'.
I was deep into 'Forex' myself from a very early age. In fact, when I lived and worked in Brisbane in 1980, I occasionally took the train from Toowong into the City and watched it from my window-seat as I passed through Milton Station.
My friend has since put a slightly different slant onto his 'forex' involvement by directing me to this link for which I am ever so grateful.
