If you are conversant with technical analysis, and use indicators such as the RSI or stochastic.

It won't exactly match the numbers for magnitude population - but we want to manage to say something this population, and, thanks to statistics, turn out to be. If we possess a random sample, we can calculate a confidence interval around the mean, and reasonably sure that the mean of the sum of population will be that confidence interval.
