The mean of prices will be the same in both a tail-heavy pattern where much of the action takes place at the edges of the range, and one where it is concentrated in the middle, but these forex hub africa patterns obey completely different rules, and applying the same mean regression strategy on the basis of a basic reading of the market action is sure to result in disaster.
