How much would it cost me to buy one gold futures contract on Comex?
The lot size is 100 troy ounce. See the contract specification at the same site; http://www.cmegroup.com/trading/metals/precious/gold_contract_specifications.html So with the current price of around $1785, one lot would cost you around 178,500. There may be other sites that offer smaller lots you would need to check with your broker. if the price moves up by $500, you gain $50,000 for a lot. The margin required changes from time to time:  Currently it's $3666, with a maintenance of $3332, so a drop of $3.34 per oz of gold will cause a margin call. You make or lose 100 times the per oz movement as there are 100oz in the contract you cited. There's also a broker fee analogous to the commission on a stock trade.  The other option would be to buy a fund that invests in Gold, this will be more easier to buy and the lot sizes will be much less. I hope you jumped into this great opportunity. At the time, experts said gold would have a straight run to $5000.
