My main observations: Gold and Crude Oils are opposite instruments of USD. If USD gets stronger (people sell other stuff and buy USD) than normally Gold and Oil start to fall/ get down.
Another thing is - do not expect to earn quick money on Gold and Oil, these are subject to a long-terms trends,especially Oil. Look and their trends or patterns in Day and Week timeframes in order to figure out your position. The bigger account you have the better, because prices ( hourly, daily) can be quite volatile and you must have enogh fund to sustain your positions. If you place too small stops and take profits - it won't work that way on Gold and Oil. Ultimately Gold is a buy on a very long term basis (monthly) but Oil is very tricky.
Also Oil is very political too, subject to rumors, bad or good expectations, political risk, and bad or good economical results of countires like China and US.
If you can - trade with Demo for several months at least to have a feeling and only after trade with real money. otherwise, this is very risky for the beginner if you do not have a trusted adviser/experienced trader who will coach you.
