1800 is a long term resistance area dating back to 2011. Once the price of gold breaks out above 1800 there is no resistance for gold until it reaches it's all time high of 1923.
There are micro mini gold contracts which are 10% the size of the gold contract, just like there are micro mini contracts for stocks. If the full size contract is more than allows you to sleep at night, then just opt for several micro contracts. No need to make this hard on yourself.
