The indicator uses SmoothAlgorithms.mqh library classes (must be copied to the 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".
The original DS_Stochastic indicator was developed in the MQL4 language and published in the CodeBase on 27.10.2006.
