how to trade commodities

Hi, I am learning to trade commodities.
can anyone give me resources that can educate me on how to trade commodities, babypip style.

i am not talking about how to make money in the market, i am talking about the actual rules and how future trading is performed. eg how to actually execute order and how to buy and sell.

I understand the basic ideas of commodity trading, it is a bit different from FX. but there are still things i don't understand, for example, If i see a instrument i want to trade, how do i know which monthly contract to trade? when people are looking at a commodity chart, are they looking at spot price or contract pricesÉ

I'm not going to be of much help cause I don't trade futures. However, gold and silver can be traded exactly like fx. Many fx brokers offer both gold and silver spot markets, ie. XAU/USD(Gold) XAG/USD(Silver). Something to think about.

Xauusd is far better to trade than silver, because it has less volatility, and can be determined to be moving in a trend easier.
