This indicator is an example of smoothing the Chaikin Oscillator indicator timeseries by filtering high-order harmonics.
You can use this approach for smoothing the output of any indicator. The major advantage of this method is that it has practically zero latency.
Indicator input parameters:
input uint                fast_ma_period=3;      // Fast period input uint                slow_ma_period=10;      // Slow period input ENUM_MA_METHOD      ma_method=MODE_LWMA;  // Smoothing types input ENUM_APPLIED_VOLUME VolumeType=VOLUME_TICK; // Volume input uint N = 7;                                // Series length input uint SS = 20;                              // Smoothing coefficient input int Shift=0;                                // Horizontal indicator shift in bars
where:
- N — sets the series length (power of two);
- SS — smoothing coefficient in the resulting spectrum zeroes out frequencies exceeding the set value. SS cannot be greater than 2^N. If SS = 2^N, the Chaikin Oscillator series is repeated.
This indicator requires the following library:
