The test_envelopesonarray.mq5 is an example indicator demonstrating how to use the CEnvelopesOnArray class. The incenvelopesonarray file must be located in the MQL5\Include\Inconarray directory of your terminal's data folder. The Inconarray folder must be created if it does not exist. The CMAOnArray class is required for this class to function correctly.
The technical indicator is formed by two lines, one shifted upward and the other shifted downward. The selection of the optimal relative number of band shifts is determined by market volatility. Higher volatility results in a stronger shift.
