Forex Slow-Stoch Indicator:
Smooth Stochastic. After the main and signal lines of the Stochastic are calculated, their values are filtered by the averaging algorithm for a better directive effect.
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”.
