I have included ports of 2 indicators from MT4 (not from the original commercial source). I couldn't cross check if these matched their commercial equivalents (you need to assume they don't!). If you own any of these in other platforms, appreciate if you could publish some comparison results here.
Kase Peak Oscillator [KPO] is the difference between two trend measurements, one for rising markets and the other for falling markets. KCD is the PeakOsc minus its own average. So, KPO takes the place of a traditional oscillator and the KCD takes place of the traditional MACD.
Ms.Kase claims KCD is far more accurate than MACD.
