A TSI oscillator based on the values of the WPR technical indicator, implemented with its own signal line in the form of a colored cloud.

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".
