Quote from Thunderdog:
You may call it that, but it's not really the case. To calculate expectancy you need a probability distribution of future market prices. Such a thing doesn't really exist for future prices no matter how much we may squint to try and make it so. What you have is an approximation based on guesstimates or past data. Hardly the stuff of mathematical precision.
Similarly, a calculator is an electronic instrument that allows you to take two seat-of-the-pants estimates, multiply them, and get accuracy to the 8th decimal point.
You left out my smiley in the quote. I was a joke, but thanks for your serious reply.
