Twenty Fisher indicators with extra smoothing in a single window.

//+----------------------------------------------+  //| Indicator input parameters                   |  //+----------------------------------------------+  input uint FLength=3;                             // initial depth of averaging  input uint  step = 1;                             // change step of the averaging depth  input Smooth_Method MA_SMethod=MODE_JJMA;         // Smoothing method  input uint MA_Length=3;                           //Smoothing depth                      input int MA_Phase=15;                            // smoothing parameter,  3//---- for JJMA within the range of -100 ... +100 it influences the quality of the transition process;  //---- for VIDIA it is a CMO period, for AMA it is a slow average period                    input ENUM_APPLIED_PRICE_ IPC=PRICE_CLOSE_;       // price constant  

The indicator uses the classes of library SmoothAlgorithms.mqh (to be copied to <terminal_data_directory>\MQL5\Include). The use of the classes was thoroughly described in article Averaging Price Series for Intermediate Calculations without Using Additional Buffers.

For the indicator to work, the XFisher_org_1.ex5 indicator must be added to the <terminal_data_directory>\MQL5\Indicators folder.
