Method BB I have yet another method, and this one here is named Method BB because it is all Bollinger Bands. Not sure if it has been done before, but I haven’t seen it around here so I am claiming it as my own! For those of you that took statistics, you may recall that Bollinger Bands are a graphical representation of standard deviations. Essentially, in normal data sets, there is a bell curve in which most numbers fall under, and there is less of the data at the extremes. As the size of the data set becomes larger, the more accurate it becomes.
