I just watched an informative video about selling credit spreads on VIX futures. There was an element about the video I don't understand. The host was explaining his strategy, Sell X, buy Y. But in his example, the prices he used were both "ask" quotes. The "bid" quotes were quite different, of course.

So there is the meat of the question. When calculating an options position, even a naked put or call, how does one calculate risk if the entry price is uncertain?

And also, what is the best order execution method? I have only bought a few calls in my career and I simply used limit buy orders and walked them up, starting at the "bid" quote on my platform.

Good Question.

Bid-Ask spreads in options are often a significant cost of trading as they are often much wider than the underlying product. Factor in that these products also have smaller delta's and you often need a much bigger price move to just cover the spread.

In terms of risk, if you entered the position and then immediately closed it with no market move at all you would expect to lose (ask-bid+commissions)*2. Now consider the following hypothetical situation. Stock is trading $100 and you buy the ATM Call. If the stock goes to $99 you stop yourself out and if goes to $103 you take profits. Hence you think you have a 3:1 reward to risk ratio. Assuming 50% delta, if stock goes to $99 you lose $.50+(ask-bid+commissions)*2 and if stock goes to $103 you make $1.50+(ask-bid+commissions)*2. If bid-ask + commissions is actually say 10c this becomes -$.50-$0.20 = -$0.70 and $1.50 - $0.20 = $1.30. hence your 3:1 reward to risk trade is actually 1.85:1! Obviously only hypothetical, but hopefully a good illustration.
