Trading in commodity futures contracts can be very risky for the inexperienced. The high degree of leverage used with commodity futures can amplify gains, but losses can be amplified as well. If a futures contract position is losing money, the broker can initiate a margin call, which is a demand for additional funds to shore up the account. Further, the broker will usually have to approve an account to trade on margins before they can enter into contracts.

The world of commodity options is diverse and cannot be given justice in a short article such as this. The purpose of this writing is to simply introduce the topic of options on futures.

In terms of valuing option contracts, it is essentially all about determining the probabilities of future price events. The more likely something is to occur, the more expensive an option would be that profits from that event. For instance, a call value goes up as the stock (underlying) goes up. This is the key to understanding the relative value of options.
A commodity market is a market that trades in primary economic sector rather manufactured products.  Soft commodities are agriculture products such as Wheat, coffee, sugar and cocoa. Hard commodities are mined products such as gold and oil. Future contracts are the oldest way of investing in commodities. Futures are secured by physical assets. Commodity market can includes physical trading in derivatives using spot prices, forwards, futures and options on futures. Collectively all these are called Derivatives.
Puts are more or less the mirror image of calls. The put buyer expects the price to go down. Therefore, he pays a premium in the hope that the futures price will drop. If it does, he has two choices: (1) He can close out his long put position at a profit since it will be more valuable; or (2) he can exercise and obtain a profitable short position in the futures contract since the strike price will be higher than the prevailing futures price.
However, for put options (right to sell), the opposite is true - with strike prices below the current share price being considered "out of the money" and vice versa. And, what's more important - any "out of the money" options (whether call or put options) are worthless at expiration (so you really want to have an "in the money" option when trading on the stock market). 
For years, the preferred method of trading options was to use a live broker with a securities firm because you would receive all the research you would need to make a judgment. But with the advances made by online brokerage companies in being able to provide you with that information, more people are trading commodity options online than ever before and they are paying a fraction of the commissions they would otherwise pay to a live broker. Since you will have more trades than you would if you were simply buying stock, you will have more money in your account.
Volatility also increases the price of an option. This is because uncertainty pushes the odds of an outcome higher. If the volatility of the underlying asset increases, larger price swings increase the possibilities of substantial moves both up and down. Greater price swings will increase the chances of an event occurring. Therefore, the greater the volatility, the greater the price of the option. Options trading and volatility are intrinsically linked to each other in this way.
When buying or selling options, the investor or trader has the right to exercise that option at any point up until the expiration date - so simply buying or selling an option doesn't mean you actually have to exercise it at the buy/sell point. Because of this system, options are considered derivative securities - which means their price is derived from something else (in this case, from the value of assets like the market, securities or other underlying instruments). For this reason, options are often considered less risky than stocks (if used correctly).
