1. As a futures option seller, it takes money to make money...leave plenty of excess margin in your commodity trading account
Short option traders must be properly funded to be capable of riding out any storm that might materialize. During times of excessive commodity market volatility, many traders turn to the limited risk of option buying. This has a tendency to artificially inflate commodity option prices, due to the increase in demand for the securities. Also, in a more volatile market environment, commodity traders often believe it is more likely that a long option strategy will have an opportunity to pay off. I argue this is a false perception because options on futures buyers must overcome their cost of entry before turning a profit; the higher the price of the option on the way in, the bigger the obstacle to being profitable will be. Nevertheless, in all of the excitement traders often behave emotionally rather than logically; as a result, they exuberantly bid up the prices of low probability options to shocking levels.
Short-Option position sizing
In most options and futures markets, you would want about $10,000 in a trading
account for one, or two, commodity options sold. In some of the higher margined markets such as gold, it would likely be in your best interest to have much more. Another way to determine the appropriate account and position size is excess margin. Generally speaking, it is a good idea to utilize 50% of less of your account when trading short options. Simply put, if your account size is $10,000 you should aim for trades that will require a margin of $3,000 to $5,000. On the flip side, the excess margin listed on the bottom of your statement should be between $7,000 and $5,000.
Some might look at the funds not being used toward margin as a missed opportunity, or a waste of risk capital. However, nothing could be further from the truth. Undercapitalized commodity option sellers will almost undoubtedly get into trouble. Without plenty of excess margin in a commodity trading account, it can be difficult to survive the normal ebb and flow of the futures markets. In addition, a lack of capital dramatically increases the odds of a margin call, which can result in pre-mature liquidation of an option trade. If the situation is dire enough, the liquidation might be at the hand of your commodity broker; which is an unpleasant experience for all parties. With that said, not all commodity option brokers are created equal (see the next talking point).
