Envelopes indicator with the color filling inside the channel, drawn as a cloud, with the display of the last values as price labels and the possibility to round the channel levels up to a required number of digits. The number of digits to round is set in the Digit input:

input uint Digit=3; //Number of digits to round to

The indicator uses the classes of SmoothAlgorithms.mqh library (copy it to <terminal_data_folder>\MQL5\Include). The use of the classes was thoroughly described in the article "Averaging Price Series for Intermediate Calculations Without Using Additional Buffers".
