I'm not sure about how to use CGOsc to create signals. John Ehlers himself shows two outputs (two lines) in his graph, but the Manual doesn't mention that. If I look at MACD or Bollinger Bands, I got 3 outputs and can create signals with cross over or under condition. Ehlers notes in http://www.mesasoftware.com/papers/TheCGOscillator.pdf "It is clear that every major price turning point is identified by the CG Oscillator and the crossovers formed by its trigger with zero lag." Where do I get the signal line from?
