I would suggest the following to enhance the signal, and therefore producing a Strategy, if possible:
1. Parameter setting for signal that would paint the VERTICAL LINE corresponding with an up trend (green)/down trend (red) when indicators are in harmony, such as I have shown on this chart.
2. Allow the user to select the "sensitivity" of the above said signal. For example, Autotrade function would trade on the premise: 1)SDL Oscillator bar used ALL in harmony 2)SD Lines ALL in harmony or 3)All SD Lines and Oscillator Bar in Harmony.
