Help req. on Gold

Hello everybody,

I'm novice to commodities and interested to trade Gold over a timeframe of 3-6 days or max 1 week. I'm totally new to this market.

Can anyone please tell me the profit potential of trading Gold (a demo trade) by just giving a recent chart and showing the entry & exit and hence the calculation of the profit realized - it's just for demo (need not be a real trade performed).

Actually, I'm totally unknown to the lot size of Gold and its volatility - Please also tell me about the volatility of Gold. Please also tell me how much does one gain/loose when the Gold price moves by 1 point.

Thanks in advance,
