There is one more element to this trade that I will keep to myself, for the most part but if you understand statistics you'll know that data in the tails represent a very small percentage of an overall data set. So, if you find yourself at a point where the data is in the tails what will happen? It reverts back to the mean. The trick is picking your start and end point to calculate the beginning and ending point to examine. These points can be determined by studying volume patterns, which is another point I strongly disagree with from the OP. Volume is VERY important!
