In download area we posted the software to generate any digital filter.
But if you prefer to use metatrader to do everything we have the special indicator for that case.
To use this indicator you must copy DF.dll file to "libraries" folder and make sure availability of Bdsp.dll, lapack.dll, mkl_support.dll in C:\Windows\System32\ folder or or in \experts\libraries\. Check "Allow DLL import" and "Confirm DLL function's call" in Options->Expert Advisors.
Description of the parameters (settings) of the indicator:
1. Filter type - 0 - LPF (FATL/SATL/KGLP)
- 1 - HPF (KGHP)
- 2 - BPF (RBCI/KGBP)
- 3 - RBF (KGBS)
2. Some extra conditions - LPF: P1>D1
- HPF: P1<D1
- BPF and RPF: D2>P2>P1>D1
Description of the other settings you may find at Discussion Area > General Discussion > Digital Filters
