There are many ways to skin this particular cat, but first you need to make up your mind about your objectives and your constraints.Let me phrase it a different way: My decisions tend to be situationally ad-hoc. That is, based on news, market trend, price, forum posts, how many cups of coffee I've had, etc. I'm trying to devise some objective way to compare trades with one another. The "way" might be subjective, but the future analysis would be entirely objective and based on specific criteria.
