Three Bollinger Bands channels based on one moving average, drawn as a colored cloud, with the display of the last values as price labels and the possibility to round Bollinger levels up to a required number of digits. The number of digits to round is set in the Digit input:

input uint Digit=2; //Number of digits to round to

The indicator uses SmoothAlgorithms.mqh library classes (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".
