Hello, I am a new at selling options on commodities. I attempted to sell an out of the money option contract on heating oil and there was a wide spread between the posted bid and ask prices listed. How do I determine a proper asking price in that kind of situation? Just split the difference? I want to do a credit spread and am unsure how to determine pricing. Also, what should be my time frame when offering a contract for sale, should I let the offer expire at the end of the day and then reevaluate the market conditions daily?
