The logic behind using the envelope indicator is to help buyers and sellers push the price to the extremes which are the higher and lower bands, after this, the prices will often stabilise by moving to more realistic levels.
Envelopes are defined by two moving averages that form an upper, lower and middle band, and these boundaries change due to market volatility. The period used for the moving averages is 14, but a standard deviation of 0.1% is used, so the moving averages are parallel to each other and are at a certain distance.
