The TTF classic indicator with T3 smoothed method and a signal line.
This indicator was first implemented in MQL4 and published in Code Base on 18.10.2007.
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".
