i trade foreign exchange for a living and bet horses,dogs,roulette and sports bet, recently into poker.
i have tonnes of live trading dealing systems set up at home and if anyone asks what i do i say im like a stock day trader (as fx is relatively new thing)
if i were you id go to
www.fxcm.com and download some demonstration software so that anyone questions you - just say ill show you what i do. that account gives you a demo 50 k and you can just play around with it.
thats if you wish to deflect the true nature of your business
for me in my industry all my friends trade so its no big deal
hope that helps gbogo - get big or get out
