Auto_Envelope - MetaTrader 5 Script | Forex Indicator Download - MT4/MT5 Resources

Auto Envelope is an envelope indicator that automatically changes the channel size and calculates the standard deviation of the last 100 bars. It is designed to change the value no more than once per week, which makes it suitable even for intraday data.

It has four inputs:

 Central = MA
Top = Center + Channel / 2.0
Bottom = Center - Channel / 2.0
Channel = StdDev * Deviation Factor * Center / 10.0
StdDev - StdDev (original, offset period)
Raw = 2.0 * Maximum (Abs (high MA), Abs (low MA)) / MA
MA - MA (Close Price, MA Period, MA Method)
