Quote from tradingjournals:
I noticed your asked this question a number of times. You may want to reflect on it more, or simply use European style options, but I would stay clear from those options that follow the price on the open on Friday. I once had an option that settles using DJS, and they played games with it on Friday---DIA traded at a price way lower than DJS (which if I recollect well is calculated using the averages of the open on stocks in the dow index).
Falconview, tis comment above is the reason I was asking the question. Are there any index options that would follow his recommendation to stay clear of those that follow the Friday open price.
